Academic literature on the topic 'Drinking of alcoholic beverages – South Africa'

AIM: The aim of this study was to examine the alcohol drinking patterns among young male and female alcohol drinkers. METHOD: Data were collected though a questionnaire from 71 grade 11 learners who expressed that they had had an alcoholic drink in the preceding month. 62% of the respondents were male and the remaining 38% was represented by female learners. The data collected was analysed using the Statistical Package for the Social Science (SPSS). RESULTS: This study showed that young people begin using alcohol at a relatively young age. Furthermore, male drinkers have an earlier alcohol debut than their female counterparts. Beer, cider and wine were the most consumed beverages, with males more inclined to drink beer and females gravitating towards drinking wine. There was an even split between ciders in the study, with the majority of both male and female respondents indicating that their drink of choice was cider. Weekends are the most opportune moments for the youth to consume alcohol. Holidays are also earmarked by the youth to engage in alcohol consumption. CONCLUSION: The results show that the age of alcohol debut is as low as 8 years for males and 10 years for females. Males have a higher prevalence of alcohol use than females. There is however no difference in binge drinking between the two gender as binge drinking and drinking to get drunk are the preferred methods of alcohol consumption for both genders.

The study of liquor provides an opportunity for re-examining relations between states and economies. Recent works in European social history have shown that liquor occupies an ambiguous space between economic, social and cultural production while studies of liquor in colonial Africa repeatedly raise the problem of how economic freedoms pertaining to liquor were constructed in relation to the perceived character of persons in society. More specifically, the notion of ‘European liquor’ in colonial discourse suggests that the liquor of colonial masters should be aspired to. ‘European liquor’ was repeatedly contrasted to indigenous brews of lower alcoholic content that were pronounced to be uncivilized and primitive. It implied that drinkers of sorghum beer, palm wine and other beverages fermented from African grains and fruits would progress to the ‘superior’ beverages of their colonial masters. Critically, it assumed that transition to the higher alcoholic content required the discipline of ‘European’ lifestyles. Gradualism, however, often gave way to expediency. Colonial regimes repeatedly set aside fears of the effect of ‘foreign’ liquor on African subjects in the interest of revenue and political gains. The importation of gin by the colonial authority in Ghana provided the regime with revenue for its administration; in colonial Nigeria and elsewhere, liquor was used by the state as a means of winning allies among chiefs.

Objective: Determine the prevalence of Dop, a system of labor payment via alcoholic beverages, in a South African province, and its influence on maternal drinking and fetal alcohol spectrum disorders (FASD). Methods: Data from studies of FASD epidemiology were analyzed. Results: Forty-two percent to 67% of mothers reported drinking. In 1999, 5% of women reported Dop allocations in their lifetime: 14% of mothers of FASD children and 1% of controls. In 2010, 1.1% of mothers reported lifetime Dop: 1.6% of FASD mothers and 0.7% of controls. Commercial alcohol sales have replaced the Dop system. Total FASD rates remained high in rural areas in 2010 and rose in urban settings. Urban rates of total FASD surpassed rural area rates in 2010. Correlation analysis did not reveal a strong or significant, direct relationship between Dop experience and heavy drinking (r = 0.123, p < 0.001, r2 = 0.015), or the diagnosis of FASD in children (OR = 0.003, p = 0.183). Conclusion: Dop, as a systematic practice, is dead and does not have a direct influence on alcohol availability, heavy maternal drinking, or the probability of an FASD diagnosis. Nevertheless, today’s problematic drinking patterns were heavily influenced (shaped) by Dop and have negatively impacted the prevalence and severity of FASD.

Data from 333 Black university students in Limpopo, South Africa were used to investigate the association between the spirituality dimensions of religious and existential wellbeing (RWB and EWB) and health risk behaviours. The mean scores of almost all health risk behaviours, with the exception of the daily eating of healthy foods, varied according to the levels of RWB (p ≤ 0.05). On the other hand, with regards to levels of EWB, the analysis of physical activity produced a gender by EWB interaction only, and the results pertaining to the drinking of alcoholic beverages were marginal (p ≤ 0.10). There was a marginal gender by EWB effect for cigarette and marijuana use (p ≤ 0.10), with a 0.019 effect size (partial eta squared) for each analysis, and a gender effect for both (p ≤ 0.001 and 0.01, respectively). Effectively, there were no instances of statistically significant main effect of EWB (p > 0.05). Apparently, the type or dimensionality of spirituality used is important, and future studies should investigate varied measures of the construct to establish its relationship with health risk behaviour.

Maize, together with its fermented products, is fundamental for human nutrition and animal feed globally. Non-alcoholic fermentation of maize using lactic acid bacteria (LAB) is one of the food preservation methods that has been utilised throughout the centuries and has played a vital role in the manufacturing of many fermented beverages consumed these days. However, the coincidence of LAB and yeasts during the spontaneous fermentation of maize-based products is inevitable. The involvement of other microorganisms such as moulds, Bacillus species and acetic acid bacteria in the fermentation of maize is important to the characteristics of the final product. Fermented beverages are affordable, have been produced traditionally and are known for their organoleptic properties, as well as their health-promoting compounds. The consumption of non-alcoholic beverages has the prospect of reducing the detrimental health and economic effects of a poor diet. Different fermented maize-based gruels and beverages such as ogi, mawe, banku and kenkey in West Africa, togwa in East Africa, as well as mahewu in South Africa have been documented. The physical and biochemical properties of most of these maize-based fermented products have been investigated and modified by various researchers. Attempts to enhance the nutritional properties of these products rely on supplementation with legumes to supply the insufficient amino acids. The production technology of these products has evolved from traditional to industrial production in recent years.

Lowering of the drinking age in three Australian States was found to adversely affect traffic safety. In the case of the South Australian reduction from 20 to 18 years the significant increase in the number of male drivers and motorcyclists injured still existed four to six years later. For Western Australia and Queensland different results were obtained for the metropolitan and Rest-of-State areas. A highly significant increase in drink-driving enforcement activity in Queensland was not able to contain the adverse effect on traffic safety of increasing the availability of alcoholic beverages.

Background. Very little is known about older adults accessing HIV care in sub-Saharan Africa.Materials and Methods. Data were obtained from 18,839 HIV-positive adults at 10 treatment programs in Burundi, Cameroon, and the Democratic Republic of Congo. We compared characteristics of those aged 50+ with those aged 18–49 using chi-square tests. Logistic regression was used to determine if age was associated with medication adherence.Results. 15% of adults were 50+ years. Those aged 50+ were more evenly distributed between women and men (56% versus 44%) as compared to those aged 18–49 (71% versus 29%) and were more likely to be hypertensive (8% versus 3%) (P<0.05). Those aged 50+ were more likely to be adherent to their medications than those aged 18–49 (P<0.001). Adults who were not heavy drinkers reported better adherence as compared to those who reported drinking three or more alcoholic beverages per day (P<0.001).Conclusions. Older adults differed from their younger counterparts in terms of medication adherence, sociodemographic, behavioral, and clinical characteristics.

AbstractThe WHO has called for governments to improve children’s food environment by implementing restrictions on the marketing of ‘unhealthy’ foods to children. Nutrient profiling (NP) models are used to define ‘unhealthy’ foods and support child-directed food marketing regulations. The aim of the present study was to assess the suitability of the South African NP model (SANPM), developed and validated for health claim regulations, for child-directed food marketing regulations. The SANPM was compared with four NP models specifically developed for such regulations. A representative list of 197 foods was compiled by including all foods advertised on South African free-to-air television channels in 2014 and foods commonly consumed by South African children. The nutritional information of the foods was sourced from food packaging, company websites and a food composition table. Each individual food was classified by each of the five NP models. The percentage of foods that would be allowed according to the different NP models ranged from 6 to 45 %; the models also varied considerably with regard to the type of foods allowed for marketing to children. The majority of the pairwise comparisons between the NP models yieldedκstatistics >0·4, indicating a moderate agreement between the models. An almost perfect pairwise agreement (κ=0·948) existed between the SANPM and the UK Food Standards Agency model (United Kingdom Office of Communication nutrient profiling model), a model extensively tested and validated for such regulations. The SANPM is considered appropriate for child-directed food marketing regulations in South Africa.

ENGLISH ABSTRACT: Objective: The purpose of the present study is to empirically examine the relationship between brand-level alcohol advertising and alcohol consumption in South Africa. The effect that price has on alcohol consumption is also investigated in the analysis. Method: Using secondary quantitative time series data that include observations of brand-level sales volume, segment volume, brand-level market share, brand-level retail selling price (RSP) and brand-level advertising expenditure (spanning a 32 month period), statistical techniques such as tests for stationarity and co-integration were conducted to assess the association between the various constructs. Results: It was found that between January 2007 and August 2009, a period that included an economic downturn, own-brand advertising had little or no effect on brand-level sales volume (or consumption), segment sales volume and brand level market share. Conversely, price had a significant effect on sales volume, explaining between 48% and 56% of the variation in sales volume at brand-level and between 21% and 31% of the variation in brand-level market share. Conclusion: The results suggest that brand-level advertising has no significant immediate effect on consumption levels in the South African liquor industry, while the price of alcoholic beverages does have a significant immediate effect.

This study investigates the effects of televised alcohol advertisements on the drinking behaviour of youth in Praktiseer community of the Greater Tubatse Municipality. The nature and trends of alcohol consumption in South Africa are examined. The study also focuses on the impact of alcohol exposure, and the costs alcohol abuse can incur on the individual and society at large. The types of advertising models and the regulatory systems in advertising were identified. Data were collected through a self- administered questionnaire. The study hypothesised that the exposure to alcohol advertisements influences alcohol abuse among the youth. However, alcohol industry claims that the youth is not its niche market and hence should not be blamed for any abusive behaviour of alcohol by the youth. Just like the few studies interested in the effects of alcohol advertising, alcohol exposure and alcohol abuse, the present study also reveals that televised alcohol advertisements have a great influence in alcohol consumption among the youth in Praktiseer community.

Thesis (D. Tech.) -- Central University of Technology, Free State, 2008
The purpose of this study was to evaluate brewing and consumption practices and to screen for micro-organisms and mycotoxins associated with traditional beer produced and consumed in the marginal urban settlements of the city of Kimberley in the Northern Cape Province of South Africa. The survey study revealed that traditional beer is no longer being brewed for traditional purposes only, as was the case in the past, but rather for commercial gain. Both brewers and consumers, however, appeared to be largely unaware of disease-causing micro-organisms present on the hands or bodies of handlers that can be transferred to the beverage during the handling process, and were seemingly not conversant with regard to the effects of hazardous ingredients sometimes incorporated during the brewing process. Unemployment and a lack of education emerged as pivotal factors related to the production of traditional beer and the ignorance of the associated safety thereof. The survey further indicated that although facilities such as the availability of potable water (taps in yards) and flushing toilets were sometimes in place, other facilities such as basins with hot running water were often not available. In commercially produced and homebrewed traditional beer the mean counts for total coliforms and Staphylococcus spp. were circa 105 cfu.ml-1 whereas the TVC (Total Viable Counts) and total fungi counts were 106 and 107 cfu.ml-1 respectively. The total coliforms and Staphylococcus spp. counts for homebrewed traditional beer were approximately one log-phase higher than the commercial version. The counts in the homebrewed beer probably originated from contamination during handling, while in the commercial product contamination originated either in the raw ingredients or during postprocessing and consumption. Apart from staphylococci, considerable numbers of total coliforms indicating faecal contamination were noted. A rapid, easy, reliable and accurate technique that could be used to quantify the level of mycotoxins (deoxynivalenol and citrinin) in the beer was developed through validation of the ELISA Ridascreen methodology. Using this method, the deoxynivalenol (DON) level in the beer samples was found to exceed the recommended levels suggested by the European Union, while citrinin levels in the samples varied between 35.6 ppb and 942.2 ppb. In the case of citrinin there were statistically significant differences between spring, summer and winter samples, confirming the seasonal impact on fungal growth and consequent mycotoxin production. An R2-value of 0.409 was noted between DON and citrinin, indicating a weak positive association. Finally, an awareness programme in the format of a poster with accompanying subscripts was developed to address issues of safety and hygiene of traditional beer in the study area. The poster utilises animatedstyle colour images of selected practices that need to be addressed, accompanied by slogans summarising the particular image in English, Afrikaans and Setswana. It is envisaged that, as part of a comprehensive awareness programme, the poster will contribute greatly to the quality, safety and promotion of traditional beer in the area.

Introduction: Studies reveal differential cognitive effects of alcohol use, with moderate to heavy alcohol having some beneficial effects in older adults, whereas in young adulthood, heavier alcohol use produces deficits. The aim of the research was to investigate the relationship between patterns of alcohol use and the cognitive and symptomatic functioning of university students over one year, and to discern which demographic, clinical and alcohol factors might moderate cognitive outcomes. Method: The sample included undergraduate Psychology students from a South African University, aged 18 to 23 years (n = 86). The sample was divided into two alcohol use groups based on four categories from the Alcohol Use Disorders Identification Test (AUDIT) (Babor et al., 2001), including a lighter drinking group (Safe/Hazardous, n = 74) and a heavier drinking group (Harmful/Dependent, n = 12). The two drinking groups were statistically equivalent for distribution of age, gender, English first language, race groups, history of neurological or psychiatric vulnerability, a measure of initial intelligence/cognitive reserve (Peabody Picture Vocabulary Test: PPVT-4) (Dunn & Dunn, 2007) and for a measure of test-taking validity (Immediate Postconcussion Assessment and Cognitive Test: ImPACT Impulse Control) (p = < 0.05 in all instances). Participants were tested on the computerized ImPACT battery (ImPACT, 2007) at three intervals over an academic year (May, August, October 2012). Repeated measures ANOVAs were used to investigate cognitive and symptomatic differences between the two alcohol use groups, in association with moderating factors. Results: The heavier drinking group revealed: (i) poorer performance on ImPACT Visual Motor Speed, Reaction Time and Cognitive Efficiency Index scores, including less ability to benefit from practice over time; (ii) symptom reports of severe Numbness/Tingling, Balance problems and Dizziness. Deleterious cognitive outcome was exacerbated by longer lifetime duration of alcohol use, passing out monthly, beer or wine drinking, smoking or substance use. Conclusion: Deleterious cognitive and symptomatic effects of heavy alcohol use are in evidence for undergraduate university students implicating current and/or cumulative alcohol induced brain impairment. The results of the study are of concern for optimal academic performance of students at an early stage of university level study, who engage in heavier (Harmful/Dependent) drinking patterns, with negative implications for future career attainment.

Background: Over the last few decades, soft drink consumption has been steadily increasing especially at an alarming rate among adolescents. Soft drinks have been associated with positive energy intake. An unhealthy diet along with a lack of physical activity is a major risk factor for health problems like overweight and obesity, cardiovascular diseases and diabetes. Children and adolescents are becoming very susceptible to the development of NCDs due to an increase in consumption of heavily processed and highly caloric foods, leading to early onset of morbidity. Aim of the study: To investigate soft drink consumption among grade 11 and 12 learners at a secondary school in Gauteng, South Africa Methods: A quantitative descriptive survey was conducted among 382 learners (grade 11 and 12) of Liverpool secondary school. A self-administered questionnaire was used to collect data. STATA version 10 was used for data entry and analysis. Results: All learners who participated in the survey reported that they consumed soft drinks over the past 12 months. Out of the 382 learners, only 55 (14.4%) were non-frequent consumers. Carbonated drinks were the most commonly consumed (73.6%). Factors such as frequent snacking (p=0.042), frequent fast food consumption (p=0.001) and easy availability of soft drinks (p=0.00) positively influenced the consumption of soft drinks. Over 55% of the learners had very poor knowledge about the health effects caused by increased consumption of soft drinks. Conclusion: In line with the high consumption of soft drinks, the level of awareness of the health effects of these unhealthy dietary practices among the learners in this study is very poor. Interventions to improve good or healthy dietary habits have to be started both at the home and school level.

ENGLISH ABSTRACT: The global RTD market was one of the fastest growing drinks categories in the world in 2002 and many brewers and spirits companies have entered the new market. The RTD category gained most of their volume from the young adult consumers and across the boundaries of wine. spirits and beer. The strategic vision of the RID market determine whether this is a short intense fashion or a permanent feature in the drinks market, given the historical precedence of the mid to late 1980's when the wine cooler boom and later the alcopops (alcoholic carbonates) phenomenon passed as quickly as it came. The purpose of the research report sets out to investigate the global RTD markets in order to determine the strategic vision for the South African market. The study did a review of the top tcn RID markets and then focussed on the strategies and performance of the Australian and United Kingdom markets, due to the level of development and similarities in culture of these markets with the South African market. The analysis of the global RID markets showed the three successful RTD models are female, androgynous and male RIDs and consumers perceived and use the three types of RTDs differently. Amongst the most important suggestions the author recommends that the biggest opportunity for the South African R TD category is to gain market share from the beer market in the male sector, which is by far the biggest seller of alcoholic beverages in South Africa. The current successes in the South African market came from female and androgynous brands, but it is very difficult to maintain brand loyalty within these segments due to the nature of the young adult consumers and female drinkers.
AFRIKAANSE OPSOMMING: Die wereld gereed·om-te-drink (RTD) mark was een van die vinnigste groeiende drank kategoriee in die wereld in 2002 en baie brouerye en spiritualieë maatskappye het tot die nuwe mark toegetree. Die RTD kategorie het die meeste van sy volume verkry van die jong volwasse verbruikers en van verskillende kategoriee soos wyn, spiritualieë en bier. Die strategiese visie van die RTD mark bepaal of dit 'n gier of 'n permanente kenmerk in die drank mark is, soos voorafgegaan van die middel tot laat 19805 toe die wyn verfrissers en later die "alcopops" (alkoholiese karbonate) verskynsel so vinnig verdwyn het as wat dit gekom het. Die doel van die navorsingsverslag is om die wereld RTD mark te ondersoek om 'n strategiese visie vir die Suid-Afrikaanse mark te bepaal. Die navorsingstudie het die top tien RTD markte ondersoek en toe gefokus op die strategiee en doeltreffendheid van die Australiese en Verenigde Koninkrykte markte as gevolg van die vlak van ontwikkeling en ooreenkomste in kulture van die markte met die Suid-Afrikaanse mark. Die analise van die wereld RTD mark het getoon dat die drie suksesvolle vorme van RTDs is vroue, tweeslagtige en mans RTDs en dat verbruikers verstaan en gebruik die drie tipes van RTDs verskillend. Van die belangrikste voorstelle wat die skrywer maak is dat die grootste geleendheid vir die Suid-Afrikaanse RTDs is om mark aandeel van die bier kategorie in die mans sektor te verkry omdat dit die grootste alkohol kategorie in Suid-Afrika is. Die huidige sukses in die Suid-Afrikaanse mark het gekom van die vroue en tweeslagtige markte, maar dit is baie moeilik om die verbruikers lojaal te hou vir die RTD produkte in die segmente as gevolg van die aard van die jong volwasse verbruikers en vroue drinkers.

International literature suggests that corporate influence is evident when governments attempt to regulate products implicated in non-communicable disease, such as tobacco, asbestos, pollution, and foods, such as trans-fat, salt and sugar. These lifestyle diseases are aptly referred to as 'industrial epidemic', since industries profit from the public's continued consumption of such products. Of these 'industrial epidemics', alcohol is a major contributor to the health burden in South Africa. In the year 2000, 7.1% of all deaths and 7% of total disability-adjusted life years have been ascribed to alcohol-related harm in the country. The tangible and intangible costs of alcohol-related harm amount to 10-12% of South Africa's 2009 Gross Domestic Product. Literature suggests that limiting alcohol use could prevent the incidence of violence, injury, risky sexual behaviours, several forms of cancer, and neuropsychiatric and physical diseases. The World Health Organisation (WHO) released two documents, The Global strategy to reduce the harmful use of alcohol (2010b) and The Global Status Report on Non-communicable Diseases (2010a), detailing the negative effects of alcohol consumption for societies. Both documents recommend that decreasing alcohol consumption through banning of alcohol advertising would have significant public health benefits, although an integrated strategy is necessary to mitigate alcohol abuse including taxation, increasing prices, limiting places of sales and increasing education on the topic. In response, the South African government proposed a draft regulation aimed at restricting alcohol advertising as an evidence-based upstream intervention. The draft Control of Marketing of Alcoholic Beverages Bill is in the process of undergoing impact assessments to determine the impact this regulation may have on South African society. Literature suggests that industry employs various political strategies to avoid such regulation. However, little is known about the strategies the alcohol industry potentially uses to influence policy development in South Africa. There is a lack of knowledge on the current strategies used by the alcohol industry to influence policy; the draft Control of Marketing of Alcoholic Beverage Bill is a case in point. This study sought to explore the complex policy formulation process in South Africa, using the draft Control of Marketing of Alcoholic Beverages Bill as a tracer case and focused on the alcohol industry, as a central actor, to understand how it - together with other actors - may influence this process. A qualitative case study approach was used, which included stakeholder mapping, 10 in-depth interviews and review of approximately 240 documents. This study makes use of two conceptual frameworks. The first framework, Berlan et al. (2014) is used to understand policy formulation as a process with multiple facets. The second framework, Roberts et al. (2004), provides four typologies of political strategies that health reformers/advocates/lobbyists employ to influence the policy process. A thematic analysis was used to analyse the data. Key themes identified were: (1) Competing and shared values - different stakeholders promote conflicting ideals for policymaking; (2) Inter-department jostling - different government departments seek to protect their own interests, hindering policy development; (3) Stakeholder consultation in democratic policymaking – policy formulation requires consultation even with those opposed to regulation; (4) Battle for evidence – industry sought to assemble evidence to use as 'ammunition' in opposition to the ban. It was concluded that networks of actors with financial interest use diverse strategies to influence policy formulation processes to contest proposed regulation. Using the policy formulation process of the draft Control of Marketing of Alcoholic Beverages Bill as a tracer case, this research is a critical enquiry into how the for-profit industry affects public health interests in South Africa; such a critical enquiry could also be applied to other non-communicable diseases. Research suggests that industries have more difficulty in pushing their agenda when policymakers are well informed, are aware of the evidence-based practice and are not motivated by economic arguments alone. There is also a lack of research that focuses on health policy analysis in low and middle-income countries, and there is a lack of research focusing on the policy formulation process in particular. Therefore, this research aims to fill a gap in addressing a lack of research on health policy analysis in the context of a middleincome country. The implications of the study are that measures to insulate policy development are needed to prevent industry influence potentially undermining public health goals, such as: government to moderate certain consultations with industry; industry to declare conflict of interest; guidelines for bureaucrats and policymakers to advise on whose evidence to consider; and guidelines for bureaucrats and policymakers to assess quality of evidence.

ENGLISH ABSTRACT: Brandy production is a multi-step process that involves grape harvesting, base wine fermentation, distillation, wood maturation and blending. Within each of these production process steps there are a number of factors that can influence the composition and resultant quality of the base wine, unaged and wood matured distillates. These factors include geographic and climatic features of the origin of grapes used, viticultural practices, grape maturity, grape variety, vintage variation, vinification techniques, storage of the base wine prior to distillation, distillation technique, age and origin of oak wood used for maturation and barrel toasting levels. The composition of flavour is extremely complex in wine and distilled beverages such as brandy. A multitude of compounds can take part in the formation of flavour, and it is rare that a particular compound, that is solely responsible for nuances of a specific flavour, is identified. Thus, taking brandy production factors and the nature of aroma and flavour into account, it is clear that thorough understanding of the complexities affecting the perception of quality in brandy is difficult. In commercial brandy production, standard operating procedures do not allow for the separate distillation of brandy base wines from different producers and mixing of base wines from different regions and producers thus occurs. This makes it difficult to determine whether the quality determination of the base wine is in fact an indication of the quality of the resultant distillate after the required period of wood maturation. Therefore, the aim of this study is to determine whether there is any merit in storing and distilling brandy base wines from different producers and regions separately. This was done by firstly determining the demographic and production factors that influence brandy base wine composition. Secondly, the influence of brandy base wine composition on the quality of the respective unaged potstill distillates as well as the ultimate style and quality of the threeyear old wood matured potstill distillates was determined. For this purpose, four potstills with a capacity of 2000 L each were isolated and used for commercial scale distillations of 33 and 25 brandy base wines in 1999 and 2000, respectively, at the DisteIl distillery in Worcester. The experimental outlay used in the study closely emulated Distell's standard operating procedures for commercial brandy production. Chenin blanc and Colombar are the two most popular grape varietals used in the making of brandy base wine in South Africa. Due to the complexity of the brandy production process, the first part of the study only focussed on South African young Chenin blanc wines, with a predominantly fermentation derived aroma. The concentration of iso-amyl acetate, hexyl acetate, ethyl caprylate, ethyl caprate, 2-phenethyl acetate and octanoic acid was significantly higher in wines awarded gold and silver medals and decreased significantly with subsequent decreases in quality categories. Ethyl lactate exhibited the opposite pattern. A quality predictor model based on the behaviour of 21 volatile compounds quantified in these wines had a resonable prediction accuracy when having to predict the quality of wines made in the same vintages as it had been trained on. It was significantly poorer when tested on a completely different vintage of wines to the ones it had been trained on. The number of vintages, number of wines per vintage and the number of compounds quantified for the model influence its prediction accuracy. Twenty-seven volatile compounds were quantified in 33 and 25 brandy base wines, their unaged and three year old distillates from 1999 and 2000, respectively. ANOVA and CART analysis showed that vintage, region, harvest time, choice of cultivar and yeast strain can have a significant influence on the volatile compound composition of brandy base wines, their unaged and three year old distillates. These factors as well as the volatile compound composition were also found to influence the sensory quality of these products. Base wines, unaged and three year old distillates originating from the De Dooms region, which predominantly cultivates table grapes, were of significantly lower quality than those from the remaining regions. Products made from grapes harvested early in the season were of significantly higher quality. The volatile aroma compound composition was found to differ significantly between the 1999 and 2000 base wines and distillates, irrespective of the exclusion of those samples that had undergone partial or complete malolactic fermentation. Consequently, quality indicating compounds may vary from vintage to vintage. The relationship between the quality of brandy base wines and the concentration of n-butanol, iso-amyl acetate, ethyl lactate, ethyl caprylate, octanoic- and decanoic acid was the same as that reported in young Chen in blanc wines in this study. In unaged distillates, increased levels of ethyl lactate also exert a negative influence on distillate quality. Iso-amyl acetate, hexyl acetate, ethyl caproate, ethyl caprylate, n-butanol, octanoic acid, ethyl caprate and decanoic acid showed some positive correlation, whilst iso-butanol, ethyl lactate, acetic acid, acetaldehyde and ethyl acetate showed a significant negative correlation to three-year old distillate quality. Sensory descriptive analysis on selected good, average and poor quality distillates using the South African brandy aroma wheel showed that there are small differences in profile between the good and average distillates, there were however significant differences between the good and poor quality distillate profiles throughout maturation. After three years of wood maturation, the aroma profile of poor quality distillates can be characterised by prominent herbaceous and woody aromas, which are more intense than the fruity aromas. Good quality distillates contained characteristically intense fruity aromas. Volatile compound concentration differences were noted during the course of and after three years of wood maturation and in barrels of varying ages. Distillates matured in new block barrels exhibited significant differences in volatile and wood compound composition after three years when compared to remaining barrels used. The style classification of the three-year old potstill distillate was influenced by demographic and production factors and volatile compound composition, but not by the sensory quality of the distillates. In summary, vintage, region, cultivar, harvest time and choice of yeast strain have a significant influence on the volatile composition of brandy base wines, their unaged and three year old potstill distillates, which in turn affects the sensory quality of these products. These effects cannot be viewed in isolation as they jointly exert an influence on the composition and quality of these products. From a commercial perspective, this study has provided a valuable indication as to which production and demographic factors can influence the quality and style of potstill brandy. Thus, future brandy base wine intake should, as far as possible, take place in such a manner to allow base wines originating from the same cultivar or region or harvest time or combination thereof (and to a lesser extent yeast strain) to be received simultaneously at the distillery for distillation.
AFRIKAANSE OPSOMMING: Brandewyn produksie is 'n veelvoudige proses wat die volgende insluit: pars van druiwe, basiswyn fermentasie, verstoking, houtveroudering en versnyding. Binne hierdie stappe is verskeie faktore wat 'n invloed op die samestelling en resultate van die basiswyn, onverouderde en verouderde distillaat kan hê. Hierdie faktore sluit die volgende in: geografiese ligging, klimaat toestande van die streek van herkoms, wingerdboupraktyke, graad van rypheid, druifvarieteit, wynoes variasie, wynbou tegnieke, opberging van basiswyn voor distillasie, distillasie tegnieke, ouderdom en oorsprong van akkerhout vir die veroudering, asook tot watter mate die vat gerooster is. Die samestelling van geur in wyn en gedistilleerde produkte soos brandewyn is uiters kompleks. 'n Menigte samestellings kan deel vorm van die inhoud van die geur, en dit is raar dat 'n bepaalde verbinding alleenlik verantwoordelik is vir 'n kenmerkende geur. Weens die verskeidenheid van produksie faktore, aroma en smaak is volledige kennis van brandewyn ingewikkeld en kompliseerd om te verstaan. In kommersiële brandewynproduksie, maak standaard werksprosedures nie voorsiening vir aparte distillasie van basiswyn van verskillende produsente nie, en die vermenging van basiswyn van verskillende streke en produsente kom voor. Dit maak dit moeilik om te bepaal of die kwaliteit van die basiswyn of die distillaat na die neergelegde periode van houtveroudering, in werklikheid 'n beslissende indikasie op die kwaliteit van die verouderde produk is. Daarom is een van die doele van hierdie studie om te bepaal of daar meriete in is om brandewyn basiswyn van die verskillende produsente en streke apart te berg en te verstook. Dit is gedoen deur eerstens, die effek van demografiese en produksie faktore op die samestelling van brandewyn basiswyn te bepaal. Daarna, om die invloed van brandewyn basiswynsamestelling op die kwaliteit van onderskeidelik die onverouderde distillate sowel as die uiteindelike styl en kwaliteit van die 3 jaar oue houtverouderde potketel distillate, te bepaal. Vir hierdie doel, is vier potketels met 'n kapasiteit van 2000 liters elk geïsoleer en vir kommersiële skaal distillasies van 33 en 25 brandewyn basiswyne in 1999 en 2000, ondeskeidelik, by DisteIl Distillerdery, Worcester verstook. Die eksperimentele uitleg wat in hierdie studie gebruik is, ewenaar DisteIl se standaard verstokingsprosedures vir kommersiële brandewynproduksie. Chenin blanc en Colombar is die twee mees populêre druifvarieteite vir die maak van brandewyn basiswyn in Suid-Afrika. As gevolg van die kompleksiteit van die brandewyn produksieproses, is die eerste gedeelte van die studie gefokus op die Suid-Afrikaanse jong Chenin blanc wyne, met 'n oorheersende fermentasie geur. Die konsentrasie van iso-amyl asetaat, heksiel asetaat, etiel kaprilaat, etiel kapraat, 2-phenetiel asetaat en oktanoë suur was aansienlik hoër in wyne wat met goud en silwer medaljes bekroon is en neem aansienlik af met afname in kwaliteit kategorieë. Etiel laktaat vertoon die teenoorgestelde patroon. 'n Kwaliteit voorspellersmodel, gebaseer op die gedrag van 21 vlugtige komponente was opgestel. Die model het redelike akkuraatheid getoon op wyne van dieselfde oesjaar as waarop oorspronklik opgelei. Die model se voorspellingsakkuraatheid was aansienlik swakker toe dit vergelyk getoets is met wyne van 'n nuwe oesjaar. Die hoeveelheid oesjare, hoeveelheid wyne per oesjaar en die hoeveelheid verbindings gebruik in hierdie model sal die voorspellingsakkuraatheid beïnvloed. Sewe-en-twintig vlugtige komponente was gekwantifiseer in 33 en 25 brandewyn basiswyne, die onverouderde en 3 jaar oue distillate vanaf 1999 en 2000, onderskeidelik. Variasie ontledings (ANOVA) en klassifikasie en regressie ontledings (CART) ontledings wys dat oesjaar, streek, parstyd, keuse van kultivar en gisrasse In aansienlike invloed op die vlugtige samestelling van brandewyn basiswyne asook hul onverouderde en 3 jaar distillate het. Hierdie faktore, sowel as die vlugtige verbinding samestellings, beinvloed ook bevind die sensoriese kwaliteit van hierdie produkte. Basiswyne, onverouderde en 3 jaar oue distillate wat vanuit die De Doorns streek, wat hoofsaaklik tafeldruif kultivars is, is van In swakker kwaliteit as die ander streke. Produkte wat gemaak is van druiwe wat vroeg in die seisoen gepars is, was van beter kwaliteit. Die vlugtige geurkomponentsamestellings het tussen die basiswyne en distillate van die 1999 en 2000 oesjare verskil, ongeag of party van die monsters gedeeltelike of volledige appelmelksuurgisting ondergaan het. Gevolglik, die konsentrasie van kwaliteitaanwysende komponente mag van seisoen tot seisoen verskil. Die verhouding tussen die kwaliteit van die brandewyn basiswyne en die konsentrasie van n-butanol, iso-amiel asetaat, etiel laktaat, etiel kaprilaat, oktanoë- en dekanoë suur was dieselfde soos gerapporteer oor die jong Chenin blanc wyne. In onverouderde distillate, het verhoogde vlakke van etiel laktaat In negatiewe invloed op distillaat kwaliteit veroorsaak. Iso-amiel asetaat, heksiel asetaat, etiel kaproaat, etiel kaprilaat, n-butanol, oktanoë suur, etiel kapraat en dekanoë suur In positiewe korrelasie, terwyl iso-butanol, etiel laktaat, asynsuur, asetaldehied en etiel asetaat betekenisvolle negatiewe korrelasie met 3jaar oue distillaat kwaliteit bewys. Beskrywende sensoriewe analises op geselekteerde, middelmatige en swak kwaliteit distillate (gedoen deur gebruik making van die Suid-Afrikaanse Brandewyn Aromawiel) wys dat daar klein verskille tussen die profiele van goeie en middelmatige distillate is. Daar is egter aansienlike verskille tussen goeie en swak kwaliteit distillataat profiele regdeur die drie jaar verouderingsperiode. Na 3 jaar van houtveroudering kan die geur profiel van swak kwaliteit distillate uitgeken word aan kruid- en houtagtige geure, wat meer intens as die vrugagtige geure is. Goeie kwaliteit distillate het intense vrugagtige-aroma eienskappe. Vlugtige verbinding konsentrasie verskille is waargeneem gedurende en na die 3jaar houtverouderingsperiode in vate wat van ouderdomme verskil. Distillate wat in nuwe blokkies vate verouder is, vertoon aansienlike verskille in vlugtige en houtkomponent samestellings na 3 jaar wanneer dit met die, wat in die oorblywende ouer vate verouder is, vergelyk word. Die styl klassifikasie van die 3 jaar oue potketeldistillaat was deur demografiese en produksie faktore sowel as vlugtige verbinding samestellings beïnvloed, maar nie met die sensoriese kwaliteit van die distillate nie. In opsomming, oesjaar, streek, kultivar, parstyd en keuse van gisrasse het 'n aansienlike invloed op die vlugtige komponent samestelling van die brandewyn basiswyne, onverouderde en 3 jaar oue potketel distillate, wat weer op hul beurt die sensoriese kwaliteit van die onderskeidelike produkte beïnvloed. Die effek van hierdie faktore kan nie in isolasie gemeet word nie, aangesien dit gesamentlik die kwaliteit van die produkte beïnvloed. Van 'n kommersiële perspektief het hierdie studie 'n waardevolle indikasie gelewer van hoe produksie en demografiese faktore die kwaliteit en styl van potketelbrandewyn kan beïnvloed. Daarom word voorgestel dat toekomstige brandewyn basiswyn innames, sover as moontlik, voorsiening moet maak om wyne van dieselfde kultivar, uit dieselfde streek, parsseisoen inaggeneem, of kombinasie daarvan, met 'n mindermate die gisrasse in aanmerking geneem, gelyktydig vir verstoking by die distilleerderye ontvang word sodat hierdie wyne apart van wyne met ander bogenoemde variasies verstook en verouder kan word.

ENGLISH ABSTRACT: The tobacco industry of South Africa has fallen under strict legislation and control measures from the South African government since the passing of the initial Tobacco Products Control Act, 1993. Further amendments have been made to the initial act, namely Tobacco Products Control Amendment Act, 1999 and the proposed Tobacco Products Control Amendment Bill, 2004. This assignment emerges against the backdrop of the alcoholic beverage industry coming under similar scrutiny to that of the tobacco industry from government legislation and control measures The main objective of this assignment was to discover the similarities, if any, between the tobacco industry and the alcoholic beverage industry of South Africa, specifically with regard to their advertising practices before legislation. The purpose of this assignment is to discover whether or not the alcoholic beverage industry can learn from the example of the tobacco industry in order to maintain its self-regulation, rather than to fall under the control of State regulation and legislation. The literature and empirical study sought to achieve the following four objectives: 1.) To gain a thorough understanding of the tobacco legislation on a global scale; 2.) To analyse the control measures and legislation of tobacco in a South African context; 3.) To identify any similarities between the tobacco industry and alcoholic beverage industry of South Africa and 4.) To identify means in which the alcoholic beverage industry can work with the State in order to maintain the self-regulation of its industry. Findings indicate that similarities arise when comparing tobacco and alcohol, as both of them have addictive qualities, are often used from a very young age and both have laws prohibiting sale to minors. The success gained in South Africa with regard to anti-tobacco initiatives and government legislation since the introduction of the first Tobacco Act in 1993, has led to certain members of society feeling that similar, if not the same, strict strategies and / or legislative measures should be used to address the public health problems relating to alcohol.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse tabaknywerheid val onder streng wetgewing en beheermaatreëls deur die Suid-Afrikaanse regering sedert die aanvanklike Wet op die Beheer van Tabakprodukte, 1993 aanvaar is. Verdere wysigings op die aanvanklike wet is aanvaar, naamlik die Wysigingswet op die Beheer van Tabakprodukte, 1999 en die voorgestelde Wysigingswetsontwerp op die Beheer van Tabakprodukte, 2004. Hierdie werk spruit voort teen die agtergrond van die alkoholdranknywerheid wat onder 'n soortgelyke soeklig geplaas is as die tabaknywerheid by wyse van regeringswetgewing en beheermaatreëls. Die hoofoogmerk van hierdie werk was om die ooreenkomste, indien enige, vas te stel tussen die tabaknywerheid en die alkoholdranknywerheid van Suid-Afrika, spesifiek met betrekking tot hul adverteringspraktyke vóór wetgewing. Die doel van hierdie werk was om vas te stel of die alkoholdranknywerheid uit die voorbeeld van die tabaknywerheid kan leer aldan nie, met die oog op die voortsetting van sy selfbeheer, eerder as om onder die beheer van Staatsregulering en wetgewing te val. Die bronmateriaal en empiriese studie was daarop toegespits om die volgende vier doelwitte te bereik: 1.) Om 'n behoorlike begrip te verkry van tabakwetgewing op 'n globale skaal; 2.) Om die beheermaatreëls en wetgewing oor tabak in 'n Suid-Afrikaanse konteks te analiseer; 3.) Om enige ooreenkomste tussen die tabak- en die alkoholdranknywerheid in Suid-Afrika te identifiseer en 4.) Om wyses te identifiseer waardeur die alkoholdranknywerheid met die Staat kan saamwerk om die selfbeheer van die nywerheid te behou. Bevindinge dui aan dat ooreenkomste wel ontstaan wanneer tabak en alkohol met mekaar vergelyk word, veral omdat albei verslawende eienskappe bevat, dikwels deur persone vanaf 'n baie jong ouderdom gebruik word en dat wetgewing albei verbied om aan minderjariges verkoop te word. Die sukses wat in Suid-Afrika rakende anti-tabakinisiatiewe en wetgewing behaal is sedert die inwerkingstelling van die eerste Wet op die Beheer van Tabak in 1993 het daartoe gelei dat sekere lede van die gemeenskap van mening is dat soortgelyke, indien nie dieselfde nie, streng strategieë en/of wetgewende maatreëls aangewend behoort te word om die openbare gesondheidsprobleme rakende alkohol aan te spreek.

This research study aimed to provide the South African beer industry and their advertising representative with insights into 18-28-year-olds’ perceptions of the communicated messaged in beer advertisements. This included the use of social and cultural references to attract their attention and the suggestions made by the advertisements about the consumption of beer in certain contexts. This research study aimed to determine the selected sample’s (NMMU students) perceptions of four South African Breweries beer brands, namely Castle Lager, Castle Lite, Carling Black Label and Hansa Pilsener, in terms of their use of references to social and cultural identity of males and females in South Africa within their television advertisements. The survey questionnaire helped determine what the selected sample’s perceptions were of each advertisement, and whether they fully understood the desired communicated message. It also helped to understand whether each advertisement captured their attention. A semiotic analysis of each advertisement was conducted to deconstruct the advertisements and to determine if they do contain elements of social and cultural identity in an attempt to sell products to their target audiences, or to affect the perceptions of the brand and drinking beer in general. This was achieved by examining the signs and imagery in each advertisement, looking specifically at the representamen, interpretant and object using Pierce’s model of a sign.
Hierdie navorsingstudie is daarop gemik om die Suid-Afrikaanse bierbedryf en sy adverteerders ‘n beter begrip te gee van verbruikers tussen die ouderdomme van 18-28, se waarnemings van die boodskappe in bieradvertensies. Dit sluit in die gebruik van sosiale en kulturele verwysings, wat veronderstel is om die verbruikers se aandag te trek, asook die suggesties wat deur die advertensies gemaak word met betrekking tot die verbruik van bier in ‘n bepaalde konteks. Die studie moes ook die gekose monster (“selected sample”), nl. die NMMU-student se persepsies bepaal van vier handelsname van die South African Breweries, naamlik Castle Lager, Castle Lite, Carling Black Label en Hansa Pilsener, en in watter mate daar in bieradvertensies oor die televisie verwys word na die sosiale en kulturele identiteit van Suid-Afrikaanse mans en vroue. Die meningspeiling het die groep se waarnemings van elke advertensie, asook of die boodskap wat gekommunikeer is ten volle verstaan word, ondersoek. Die vraelys kon ook vasstel of die advertensies hulle aandag getrek het. ‘n Semiotiese ontleding van elke advertensie is gedoen, om die advertensies te dekodeer en sodoende vas te stel of die adverteerders elemente van sosiale en kulturele identiteit gebruik het om hul produkte aan die teikenmarkte te verkoop, of om die idees rondom die handelsnaam en bier oor die algemeen te beïnvloed. Aan die hand van Peirce se semiotiese model is die tekens en beelde in elke advertensie bestudeer.
