A number of previous studies have found that wine experts can more accurately discriminate between and describe wine samples than novices. However, the mechanisms that underlie these disparities remain unclear. This collection of studies is an investigation of whether the expert advantage is based on long-term memory structures, such as found for other obviously more cognitive skills, such as chess and bridge expertise. Experiments 1, 2 and 3 investigated whether wine experts are better than novices in recall of wine descriptions. It was hypothesised that experts would show more accurate recall than novices, although only when the descriptions were configured in a meaningful manner, that is, consistent with grape varieties commonly grown in Australia. The findings were as expected, with experts showing impaired recall for descriptions that did not match any grape variety (Experiment 2). In addition, expert recall was superior on an incidental task (Experiment 3), when recall was unexpected, suggesting that experts automatically refer to verbal long-term memory structures during a wine-related task. These structures consist of wine-relevant terms, and are organised by their relationship to grape varieties, and more broadly, grape colour. Experiments 4, 5, 6 and 7 investigated the role of the above-mentioned long-term memory structures in expert descriptive ability. The results supported their involvement, since expert�s ability to identify components was affected by sample configuration (Experiment 6) in a similar way to that found for recall of wine descriptions. Additional evidence comes from the finding that, novices, when provided with a small set of grape-relevant labels during a descriptive task, performed better than subjects given either no list or a long list of labels relevant to all the different grape varieties (Experiment 4). While experts correctly identified more flavours than novices, they also made more errors (Experiment 6), suggesting that verbal long-term memory structures do not increase the accuracy of the identification of aromas and flavours by experts. Rather, they inform experts as to which labels are likely to be correct for particular styles of wine. Experiments 8, 9 and 10 investigated both the discrimination performance of novices, intermediates and experts, as well as the role of long-term memory structures in any expert discriminative advantage. Experts (Experiments 8 and 10) and intermediates (Experiment 9) showed greater powers of discrimination than novices. However, results were equivocal in relation to the role of verbal long-term memory structures (Experiment 10), suggesting that other factors, such as perceptual learning and or memory, may be important in the expert discriminative advantage. Overall, results from these studies illustrate that long-term memory structures are essential, not only in domains of expertise that are obviously based on cognitive skills, but also that of descriptive ability with respect to wine. However, unlike in other domains, these structures do not serve to improve the relative accuracy of descriptive performance, at least with regard to aromas and flavours.

Thesis (M. Sc.Voedselwet.)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: Phenolic compounds in wine, due to their antioxidant activity, are reportedly responsible for the health-promoting properties of wines. The effect of cultivar and in-bottle ageing on the antioxidant activity of South African wines in different types of antioxidant assays was, therefore, investigated. The antioxidant activity of commercial South African red (Cabernet Sauvignon, Ruby Cabernet, Pinotage, Shiraz, Merlot) and white (Sauvignon blanc, Chenin blanc, Chardonnay, Colombard) cultivar wines was compared using the 2,2’-azino-di-(3-ethylbenzothialozine-sulphonic acid) radical cation (ABTS·+) scavenging, 2,2-diphenyl-1-picrylhydrazyl radical (DPPH·) scavenging and microsomal lipid peroxidation (MLP) assays. The red wines was more effective than the white wines on an “as-is” and an equal total phenol content. The total antioxidant activity (TAAABTS and TAADPPH) of Ruby Cabernet was the lowest of the red wines, but the antioxidant potency (APABTS and APDPPH) of red wine phenolic fractions did not differ (P ³ 0.05). Ruby Cabernet and Pinotage were the least effective inhibitors of MLP, while Merlot was the most effective of the red wines. Pinotage phenolic fractions had lower (P < 0.05) APMLP than that of other red wines. Of the white wines, Chardonnay and Chenin blanc had the highest and lowest effectivity respectively according to all antioxidant parameters. Ascorbic acid present in some wines increased and decreased their TAA and % MLP inhibition respectively. TAA and % MLP inhibition correlated well (r ³ 0.7, P < 0.001) with total phenol content of red and white wines, as well as with flavanol content of red wines and tartaric acid ester content of white wines. The % MLP inhibition also correlated well with flavanol content of white wines. No correlation (P > 0.01) was obtained between TAA or % MLP inhibition and monomeric anthocyanin content of red wines. In the deoxyribose assay, red wines were more pro-oxidant and exhibited lower hydroxyl radical scavenging and metal chelating abilities than white wines. The effect of in-bottle ageing on antioxidant activity of wines was determined using the ABTS·+ and DPPH· scavenging assays. The TAA and total phenol content of experimental red (Pinotage and Cabernet Sauvignon)and white (Chardonnay and Chenin blanc) cultivar wines, decreased (P < 0.05) during 12 months of storage at 0, 15 and 30 ºC. The TAAABTS of Cabernet Sauvignon and Chardonnay, stored at 30 ºC were lower (P < 0.05) than at 0 ºC. The APABTS and APDPPH of most wines also decreased during storage. The monomeric anthocyanin content of red wines decreased (P < 0.05) rapidly at 15 and 30 ºC. The flavanol content of wines (except Chenin blanc) increased during the first 9 months, decreasing again after 12 months, while minor changes in the flavonol and tartaric acid ester content of both red and white wines were observed. The TAAABTS exhibited a good correlation (r ³ 0.7, P < 0.001) with total phenol content of red and white wines, as well as with flavonol and tartaric acid ester content of red and white wines and flavanol content of white wines. The monomeric anthocyanin content of red wines correlated (r = 0.50, P < 0.001) weakly with TAAABTS. The decrease in the TAAABTS of wines could thus be mainly attributed to a decrease in their total phenol content. / AFRIKAANSE OPSOMMING: Die antioksidant aktiwiteit van fenoliese komponente in wyn is waarskynlik verantwoordelik vir die gesondheidsvoordele daarvan. Die studie het dus gepoog om effek van kultivar en veroudering na bottelering op die antioksidant aktiwiteit van Suid-Afrikaanse wyne te ondersoek. Die antioksidant aktiwiteit van kommersiële Suid-Afrikaanse rooi (Cabernet Sauvignon, Ruby Cabernet, Pinotage, Shiraz, Merlot) en wit (Sauvignon blanc, Chenin blanc, Chardonnay, Colombard) kultivarwyne is vergelyk deur middel van die 2,2’-azino-di-(3-etielbensotialosien-sulfoon suur)-radikaal katioon (ABTS·+) vernietigingstoets, 2,2-difeniel-1-pikrielhidrasielradikaal (DPPH·) vernietigingstoets en mikrosomale lipiedperoksidasietoets (MLP). Die antioksidant aktiwiteit en die antioksidant kragtigheid (AK) van die rooiwyne was beter as dié van witwyne in al drie antioksidant toetse. Die totale antioksidant aktiwiteit (TAAABTS en TAADPPH) van Ruby Cabernet was die laagste van die rooiwyne, terwyl die AKABTS en AKDPPH van rooiwyn fenoliese fraksies nie van mekaar verskil (P ³ 0.05) het nie. Van die rooiwyne, het Ruby Cabernet en Pinotage die laagste en Merlot die hoogste effektiwiteit in die MLP toets getoon. Die AKMLP van Pinotage se fenoliese fraksies was die laagste van die rooiwyne. Die witwyne, Chardonnay en Chenin blanc, het onderskeidelik die beste en swakste antioksidant aktiwiteit en AK van die witwyne getoon in al drie antioksidant toetse. Askorbiensuur wat in sommige witwyne voorgekom het, het die TAA van hierdie wyne verhoog, maar hul % MLP inhibisie verlaag. Die TAA en % MLP inhibisie het goed gekorreleer (r ³ 0.7, P < 0.001) met die totale fenolinhoud van rooi- en witwyne, asook die flavanolinhoud van rooiwyne en die wynsteensuur-esterinhoud van witwyne. Die % MLP inhibisie het ook goed gekorreleer met die flavanolinhoud van witwyne. Geen korrelasie (P > 0.1) is waargeneem tussen antioksidant aktiwiteit van rooiwyne en hul monomeriese antosianien-inhoud. Rooiwyn was meer pro-oksidatief in die deoksieribose toets as witwyne, maar was die swakste hidroksieradikaalvernietigers en metaalcheleerders.Die effek van veroudering na bottelering op die antioksidant aktiwiteit van wyne soos bepaal met die ABTS·+ en DPPH· vernietigingstoetse, is ondersoek. Die TAA en die totale fenolinhoud van eksperimentele rooi- (Pinotage en Cabernet Sauvignon) en witwyne (Chardonnay en Chenin blanc) het afgeneem (P < 0.05) tydens opberging na bottelering by 0, 15 en 30 ºC oor 12 maande. Opberging by 30 ºC het ‘n groter vermindering (P < 0.05) in die TAAABTS waarde vir Cabernet Sauvignon en Chardonnay veroorsaak as by 0 ºC. Die meeste wyne se APABTS en APDPPH waardes het ook verminder (P < 0.05) na 12 maande. Drastiese vermindering (P < 0.05) in die monomeriese antosianieninhoud van rooiwyne is opgemerk tydens opberging by 15 en 30 ºC. Tydens die eerste 9 maande se opberging het die flavanolinhoud van wyne toegeneem (P < 0.05) en daarna afgeneem (P < 0.05) tot by 12 maande, terwyl flavonol- en wynsteensuuresterinhoud van beide rooi- en witwyne min verandering ondergaan het. Die totale fenolinhoud van rooi- en witwyne, asook die flavonol en wynsteensuur-esterinhoud van rooi-en witwyne en die flavanolinhoud van witwyne, het goed gekorreleer (r ³ 0.7, P < 0.001) met die TAAABTS. In teenstelling met die resultate vir kommersiële kultivarwyne, was die TAAABTS van rooiwyne swak gekorreleer (r = 0.5, P < 0.001) met hul monomeriese antosianieninhoud. Die afname in TAAABTS van wyne tydens veroudering kon dus meestal toegeskryf word aan die afname in hul totale fenolinhoud.

Thesis (MSc)--Stellenbosch University, 2007. / ENGLISH ABSTRACT: With ever increasing pressure on wine producers to lower the financial costs involved in winemaking to be able to compete in the market, all while maintaining a high level of wine quality, the focus on maintaining control over all aspects of the winemaking process are greatly emphasized. Malolactic fermentation (MLF) is one of the important processes in red wine production. The advantages of this process, when performed successfully, is widely known and accepted. One way to gain control over MLF is the use of MLF starter cultures. Starter cultures usually consist of Oenococcus oeni that has been isolated from grapes or wines and is in most cases available in a freeze-dried form ready for direct inoculation into the wine when MLF is desired. Starter cultures are induced into wine and usually ensure the immediate onset as well as a fast and clean execution of the process. Starter cultures used in South Africa are in most cases isolated from cooler viticultural regions in the Northern hemisphere. The constitution of wines from cooler viticultural regions, differ from those in South Africa, which has a warm climate. The most important difference is the acid content of the wines which is lower in South African must/wines and results into a higher pH. The three most important changes that develop in wine during MLF are a decrease in acidity due to the conversion of malic acid to the less harsh lactic acid, enhanced flavour and aroma of wine and an increase in the microbiological stability of wine. The decrease in acidity is very important for wines produced for grapes grown in cool viticulture regions. In South Africa though, the climate is warm and higher pH’s are present in the musts and wines and the de-acidification due to MLF is not the main aim but rather the microbiological stabilisation. One of the compounds that could be produced by lactic acid bacteria (LAB) is biogenic amines (BA’s). These compounds can be hazardous to human health. This thesis focussed on the performance of MLF starter cultures in high pH South African red wines. The first objective of the study was to stretch MLF starter cultures in high pH red wines of South Africa. Stretching means to use less than the prescribed dosage or the re-use of starter cultures. The difference in MLF rate, the influence of the natural occurring LAB and the levels of biogenic amines formed during MLF were determined for the different stretching treatments. The results showed that different rates in malic acid degradation were experienced between the treatments, but in all cases MLF fermentation was completed. Biogenic amines were formed at various levels and the influence of the natural occurring LAB also played a role. The second objective of the study was the evaluation of the effect of a wine isolated LAB (Lactobacillus) and an acetic acid bacteria (AAB), inoculated with a MLF starter culture had on MLF at different wine pH’s. It was found that especially in the case where the Lactobacillus was inoculated in combination with the MLF starter culture a possible stimulatory effect was experienced with regards to malic acid degradation rate. Biogenic amine concentration was measured at the end of MLF and it was found that no histamine and tyramine were formed in any of the treatments, while the putrescine and cadaverine levels were found to be at approximately similar levels for the different treatments. The third objective was to evaluate the possible influence of commercial tannin additions and a pectolytic enzyme on rate of MLF and phenolic composition of high pH red wine. The commercial tannins had possible inhibitory as well as stimulatory effects on the rate of malic acid degradation especially during the initial stages of MLF, with the highest dosage having the significant effect. The BA results showed difference in the levels produced due to tannin additions as well as strain differences could exist. The phenolic content showed a decrease in colour density, total red pigments, total phenolics and anthocyanins between AF and MLF. The fourth objective was to evaluate inoculation time of MLF starter cultures. The results showed that the fastest AF/MLF time was with simultaneous inoculation of the yeast and MLF starter cultures. It was also for this treatment where no histamine or tyramine was detected at the end of MLF compared to the other inoculation strategies (before the end of AF and after AF). This study generated a large amount of novel data which made a valuable contribution with regards to MLF in high pH red wines of South Africa. / AFRIKAANSE OPSOMMING: Die druk om wyne van hoë gehalte teen lae insetkoste te lewer om deel te bly van ’n kompeterende mark, plaas die fokus weer sterk op onder andere die beheer van alle aspekte van die wynmaak proses. Appelmelksuurgisting (AMG) is een van die belangrikste prosesse van rooiwyn produksie. Die voordele van AMG, in die geval van die suksesvolle implementering daarvan is vandag bekend en word geredelik aanvaar. Een van die metodes om beheer te verkry oor the proses van AMG is deur die gebruik van AMG aanvangskulture. AMG aanvangskulture bestaan uit Oenococcus oeni wat geïsoleer word vanaf druiwe of mos/wyn en is in meeste gevalle beskikbaar in ’n gevries-droogte vorm wat direk in wyn geïnokuleer kan word. Aanvangskulture word in wyn geïnduseer om die onverpose aanvang van AMG te bewerkstellig asook om ’n vinnige en skoon deurvoering van die proses te verseker. Die aanvangskulture wat in Suid-Afrika vir hierdie doeleinde gebruik word is in meeste van die gevalle verkry uit koue wingerdbou gebiede in die Noordelike Halfrond. Die samestelling van druiwe van koue wingerdbou gebiede en dié van Suid-Afrikaanse warm wingerdbou gebiede verskil. Die belangrikste verskil word ervaar in die suur inhoud, wat laer is in Suid-Afrikaanse druiwe en dus lei tot ‘n hoër pH inhoud. Die drie mees belangrikste veranderinge wat gedurende AMG in wyn plaasvind is die vermindering van die suur, as gevolg van die omskakeling van appelsuur na melksuur, die verbetering van die aroma en geur van wyn en die verbeterde mikrobiologiese stabiliteit. Die afname in suur is veral belangrik in wyne van koue wingerbou gebiede omdat die suur-inhoud daarvan soveel hoër is. In Suid-Afrika kan hierdie verlaging in suur egter lei tot ’n verdere verhoging in die pH wat plat wyne en uiteindelik ’n verlaging in die kwaliteit van wyn tot gevolg kan hê. Biogene amiene (BA) is verbinding wat melksuurbakterieë (MSB) kan vorm gedurende AMG en kan ernstige implikasies hê vir die mens se gesondheid. Hierdie tesis fokus op die evaluering van AMG aanvangskulture in hoë pH rooi wyne van Suid-Afrika. Die eerste doelwit gedurende hierdie studie was om AMG kulture te rek en die invloed daarvan in hoë pH rooiwyn te evalueer ten opsigte van the tempo van AMG, die rol van die natuurlike MSB te bestudeer asook om die vlak van biogene amiene te bepaal vir die verskillende behandelings. Die resultate het aan die lig gebring dat die rek van kulture verskille in die tempo van appelsuur afbraak tot gevolg het, maar dat AMG in alle gevalle wel suksesvol deurgevoer kon word. Die BA’e wat gevorm is, was teenwoordig in verskillende hoeveelhede. Die tweede doelwit was om die effekt van die gesamentlike inokulasie van ’n wyn geisoleerde MSB (Lactobacillus) asook ’n asynsuurbakterie (ASB) met ’n kommersiële AMG aanvangskultuur op AMG te evalueer. Hierdie eksperiment is uitgevoer by verskillende pH’s. Daar is gevind dat veral in die kombinasie inokulasie met die Lactobacillus, die tempo van appelsuur afbraak moontlik gestimuleer was. Geen histamien of tiramien is tydens AMG gevorm in hierdie eksperiment gevorm nie, terwyl putresien en kadaverien teenwoordig was teen ongeveer gelyke vlakke vir die behandelings. Die derde doelwit was om die moontlike invloed van kommersiële tannien toevoegings en die toevoeging van ’n pektolitiese ensiem te evalueer ten opsigte van AMG tempo die fenoliese samestelling van rooiwyn te bestudeer. Verskillende kommersiële tanniene het ’n moontlike sowel as inhiberende uitwerking gehad, veral gedurende die aanvanklike stadium AMG. Die grootste verskille is waargeneem in die behandelings waar die hoogste dosisse tannien bygevoeg is. Die BA resultate toon dat verkillende vlakke geproduseer was en dat hierdie verskille onstaan het as gevolg van verskille in tannien dosisse sowel as aanvangskulture. Die fenoliese inhoud het ’n afname in kleur intensiteit, totale rooi pigmente, totale fenole en antosianiene getoon vir die periode vanaf AF tot die einde van AMG. Die vierde doelwit was om the tyd van inokulasie van AMG aanvangskulture te bestudeer. Die resultate het getoon dat die vinningste tydperk van AF/AMG was ondervind in die geval waar die gis aanvangskulture gelyktydig met die AMG aanvangskulture geïnokuleer was. Geen histamine en tyramine het ook in hierdie behandeling ontwikkel nie, terwyl daar wel vlakke teenwoordig was in die ander behandelings (inokulasie net voor die einde van AF en na afloop van AF). Tydens hierdie studie is ’n groot hoeveelheid nuwe data geskep wat ‘n groot bydrae ten opsigte van AMG in hoë pH rooi wyne vanaf Suid-Afrika kan lewer.

The aim of this thesis is to examine family wineries’ wine tourism diversification decisions in terms of wine producers’ self-constructions. The focus lies on understanding which motives drive family businesses’ decisions to engage in diversification. A case study approach is adopted, using the Italian wine region of Langhe in Piedmont. The dominant debates within the current literature have primarily concentrated on the economic-social dichotomy in relation to diversification decisions. It has been argued that diversification decisions are predominantly economically driven, highlighting the importance of profit maximisation and risk reduction. This thesis highlights the limitations of the economic-social dichotomy approach and argues for the need to take the social context into account when examining the decision-making process. An interpretivist approach to research is adopted in order to extend current understandings of family businesses and their motives underlying diversification decisions. In line with the interpretivist perspective, this thesis uses discourse analysis (DA) as a methodological approach for analysing and interpreting wine producers’ accounts. The findings reveal that by engaging in discourse about wine tourism diversification, wine producers construct a distinctive, coherent and desired sense of self, which in turn influences family wineries’ decisions to diversification. In this instance, the concept of identity formation plays a central role in explaining family wineries’ motives for diversification. Linking wine producers’ motives for diversification to their self-constructions provides a new insight into how family businesses engage in decision-making. Wine producers’ discourses reveal that their decision-making processes are inextricably linked to sustaining a positive sense of self. Decisions are not only taken to achieve economic goals, but are likely to be influenced by deeper motives, notably wine producers’ identity constructions. The main contribution of this thesis is that it advances understanding of family businesses’ decisionmaking processes by developing a multi-layered conceptual framework to go beyond the economic-social dichotomy in order to reveal wine producers’ semi-conscious and unconscious motives for diversification.

Thesis (MTech (Civil Engineering))--Cape Peninsula University of Technology, 2017. / Currently in South Africa, most wastewater from small cellars is pH-adjusted and disposed of via land irrigation. This practice can lead to environmental degradation. There is a need for low cost, low maintenance solutions for the treatment of cellar effluent. Constructed wetlands provide such an option. However, the use of plants is problematic because winery effluent can be phytotoxic. After successful initial laboratory-scale experiments, an in-situ pilot scale biological sand filter (unplanted constructed wetland) system was designed, installed, and used to treat effluent from a small winery in the Western Cape, South Africa. The system is off-grid, totally self-regulating, and uses a modular approach which allows for the addition and subtraction of filter modules within the system to alter treatment capacity, retention time and/or rest filter modules. The system can be easily integrated into existing settling basins and/or retention ponds at small wineries. The biological sand filter was operational for 610 days, and showed promising results. The average chemical oxygen demand removal efficiency was 81% (range: 44-98%) with an average effluent of 324 mg/L, and an average flow rate of 413 L/day after the acclimation (start-up) period. The average hydraulic loading rate after the initial start-up period was 143 L/m3 sand day-1 (range: 67-222/m3 sand day-1), with an organic loading rate of 205 gCOD/m3 of sand day-1 (range: 83-338 gCOD/m3 sand day-1) which resulted in an organic removal rate of 164 gCOD/m3 of sand day-1. There was an average of 67% removal of total phenolics, thereby reducing the potential phytotoxicity of the effluent. In addition, there was a 1.6 times increase in calcium concentration, a 29% decrease in the average sodium adsorption ratio, and complete passive neutralisation of the acidic winery wastewater (final effluent pH range: 6.63 – 8.14. The findings of this study compare well with previous laboratory studies conducted with synthetic and authentic winery effluent. The system can potentially provide a low cost, energy efficient, low maintenance, sustainable means of treating cellar effluent at small wineries. Uptake of this technology may alleviate environmental degradation caused by irrigating land with inadequately treated effluent.
