Thesis (PhD (Viticulture and Oenology. Wine Biotechnology))--Stellenbosch University, 2008. / The occurrence of sluggish and stuck fermentations continues to be a serious problem in the global wine industry, leading to loss of product, low quality wines, cellar management problems and consequently to significant financial losses. Comprehensive research has shown that many different factors can act either in isolation, or more commonly synergistically, to negatively affect fermentative activity of wine yeast strains of the species Saccharomyces cerevisiae. The individual factors most commonly referred to in the literature are various nutrient and oxygen limitations. However, other factors have been shown to contribute to the problem. Because of the mostly synergistic nature of the impacts, no single factor can usually be identified as the primary cause of stuck fermentation. In this study, several strategies to evolutionarily engineer wine yeast strains that are expected to reduce the occurrence of stuck and sluggish fermentations are investigated. In particular, the investigations focus on improving the ability of wine yeast to better respond to two of the factors that commonly contribute to the occurrence of such fermentations, nitrogen limitation and the development of an unfavorable ratio of glucose and fructose during fermentation. The evolutionary engineering strategies relied on mass-mating or mutagenesis of successful commercial wine yeast strains to generate yeast populations of diverse genetic backgrounds. These culture populations were then exposed to enrichment procedures either in continuous or sequential batch cultivation conditions while applying specific evolutionary selection pressures. In one of the stragegies, yeast populations were subjected to continuous cultivation under hexose, and especially fructose, limitation. The data show that the strains selected after this procedure were usually able to out-compete the parental strains in these selective conditions. However, the improved phenotype was not detectable when strains were evaluated in laboratory scale wine fermentations. In contrast, the selection procedure in continuous cultivation in nitrogen limiting conditions proved to be highly efficient for the generation of yeast strains with higher total fermentative capacity in low nitrogen musts. Furthermore, yeast strains selected after mutagenesis and sequential batch cultivation in synthetic musts with a very low glucose on fructose ratio showed a fructose specific improvement in fermentative capacity. This phenotype, which corresponds to the desired outcome, was also present in laboratory scale wine fermentations, where the discrepancy between glucose and fructose utilization of the selected strains was significantly reduced when compared to the parents. Finally, a novel strategy for the rectification of stuck fermentations was adjusted to industrial conditions. The strategy is based on the use of a natural isolate of the yeast species Zygosaccharomyces bailii, which is known for its preference of fructose. This process was successfully established and implemented in the wine industry.

Thesis (MBA (Business Management))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: The South African wine industry has made huge strides in the global wine market since one-channel marketing through the KWV was abandoned and the South African produced wines entered the traditional and emerging wine markets in Europe, Eastern Europe and the Americas. It did not take the South African wine producers and marketers very long to shift their focus to the international markets where deals made in the international currencies held the promise of great profits for successful wine exporters. With the opening of the markets, the trends and tastes of these buyers also influenced the wine styles and the way the South African producer managed his business. Although wine making in South Africa dates back over three hundred years, the re-entering into international wine markets held a great challenge to producers who were unfamiliar with the forces that dictated what and how things had to be done in the international wine arena. The emergence of the new potential for wine producers in global wine markets caught the attention of successful businessmen who ventured into wine making, as most had already developed a passion for wine. Dr. Christo Wiese bought Lanzerac wine Estate in the early nineties, and a few years later bought one of the historic farms in the Western Cape called Lourensford. He set out to develop this fruit farm into one of the top family-owned Wine Estates in the country, with the aim of creating a world renowned South African family-owned wine brand. With a state-of-the-art gravity fed winery and nearly four hundred hectares of vines planted in less than 8 years, this wine brand is slowly but surely starting to emerge on the international wine front. The task ahead is as difficult as the first ten years, but there are a lot of positives and negatives in the development of this premium wine brand that can be used by other business leaders in their decision-making when they start out on the journey to develop a brand. This report documents the first ten years of the Lourensford wine brand and it serves both as a recording of the history as well as a teaching tool for students in wine marketing as it includes interviews with people and role players that were involved and today are still involved in actively building this wine brand. The development of the Lourensford wine brand was started while the vineyards were still very young, and as such the quality of the wines were not ultra-premium from the outset. It was difficult to market these first vintages to get the cash flow right, while at the same time trying to convince the market that this Estate will eventually be producing ultra-premium wines. The focus in the beginning was production oriented, but it had to change to a more market-oriented business. By learning from the mistakes and evaluating the recommendations of this example, the reader can avoid the pitfalls of building a new brand and apply the lessons learned in his or her own business. / AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse wynbedryf het groot vooruitgang op die globale wynmark gemaak sedert daar in 1994 afstand gedoen is van die KWV se eenkanaalbemarkingstelsel en die Suid-Afrikaanse produsente weer toegelaat is om hul wyne op die tradisionele en ontluikende wêreldmarkte in Europa, Oos-Europa en Amerika te verkoop. Dit het nie die Suid-Afrikaanse produsente en bemarkers baie lank geneem om hul fokus te verskuif van die plaaslike na die internasionale wynmarkte waar die potensiaal om handel te dryf in internasionale geldeenhede, die belofte van groot winste ingehou het nie. Met die oopstel van hierdie markte het die voorkeure en smake van die wynkopers ook die wyse waarop die Suid-Afrikaanse produsente wyne gemaak en hul wynbesighede bedryf het, beinvloed. Alhoewel wynmaak in Suid-Afrika meer as driehonderd jaar lank reeds bedryf word, het die hertoetrede tot die internasionale wynmarkte ook baie groot uitdagings aan wynprodusente gestel,want hulle was nie voorheen blootgestel aan die markkragte wat die manier van handel dryf op internasionale markte beheer het nie. Die ontluiking van nuwe potensiaal vir wynprodusente op internasionale markte het ook die aandag getrek van suksesvolle sakeleiers om te begin wyn maak omdat hulle reeds 'n passie vir wyn gekoester het. Dr. Christo Wiese het in die vroeë negentigerjare die Lanzerac-wynlandgoed gekoop, en 'n paar jaar later een van die historiese plase in die Wes-Kaap, naamlik Lourensford. Hy het dit hom ten doel gestel om hierdie vrugteplaas tot 'n top wynlandgoed in familiebesit,te ontwikkel. Met 'n ultra-moderne, gravitasiegedrewe wynkelder en nagenoeg vierhonderd hektaar wingerd aangeplant in minder as agt jaar, is Lourensford stadig maar seker besig om naam te maak op die internasionale wynfront. Die taak wat nog voorlê is net so uitdagend as die afgelope tien jaar, maar daar is reeds heelwat positiewe en negatiewe lesse wat uit die ontwikkeling van hierdie premiewynhandelsmerk geleer kan word en wat ander sakeleiers in hul besluitnemeningsprosesse kan gebnuik op pad na die ontwikkeling van 'n handelsmerk. Hierdie werkstuk dokumenteer die eerste tien jaar van die Lourensford-wynhandelsmerk en dien as die optekening van die geskiedenis sowel as die verskaffing van 'n opvoedkundige hulpmiddel vir studente in wynbemarking omdat dit onderhoude bevat met rolspelers en mense wat aktief betrokke was, en vandag steeds betrokke is, by die uitbouing van die handelsmerk. Die ontwikkeling van die Lourensford-wynhandelsmerk het begin toe die wingerde baie jonk was, en as sulks was die gehalte van die wyn nie van die staanspoor af van hoogstaande gehalte nie. Dit was moeilik om die eerste oesjare se wyne te bemark om die kontantvloei reg te kry, terwyl daar terselfdertyd gepoog is om die mark te oortuig dat die landgoed uiteindelik ultrapremiewyne gaan produseer. Die fokus aan die begin was produksiegedrewe, maar moes mettertyd na 'n meer markgedrewe besigheid verander. Deur te leer uit die foute wat gemaak is, en die aanbevelings te evalueer, kan die leser die slaggate vermy wanneer kritieke besluite rakende die vestiging van 'n handelsmerk in sy of haar eie besigheid geneem moet word.

Thesis (MscAgric (Viticulture and Oenology))--University of Stellenbosch, 2007. / The rapid expansion of the world wine industry has increased the pressure on wine producers to produce high quality, distinguishable wines. The use of sensory evaluation alone as a tool to distinguish between wines is limited by its subjective nature. Chemical characterisation using analytical methods and data analysis techniques are increasingly being used in conjunction with sensory analysis for comprehensive profiling of wine. Analytical chemistry and chemometric techniques are important and inextricable parts of the chemical characterisation of wine. Through this process insight into the inherent composition of wines, be it in a general sense or related to a particular wine category is gained. Data generated during chemical characterisation are typically compiled into electronic databases. The application of such information towards wine quality control includes the establishment of industry benchmarks and authentication. The current project is part of The South African Young Wine Aroma Project, a long term research initiative funded by the South African Wine Industry with the ultimate aim to establish a comprehensive, up-to-date, database of the volatile composition of young wines. The data generated during this thesis represent the first contribution towards realising this ambition. Three clearly defined aims were set for this project, the first of which is the chemical characterisation of South African young wines in terms of selected volatile and non-volatile compounds and Fourier transform infrared spectra, with particular focus on the volatile composition. FTMIR spectra are information rich and non-specific instrumental signals that could provide invaluable information of the inherent composition of the wines. The second aim is the evaluation of the analytical methods used to generate the data and in the last instance, the optimisation of FTMIR spectroscopy for rapid quantification of major wine parameters and volatile compounds. The concentrations of 27 volatile compounds in South African young wines were determined by gas chromatography coupled to flame ionisation detection (GC-FID) using liquid-liquid extraction of the analytes. Wine samples of the 2005 and 2006 vintages produced from six of the most important cultivars in the South African wine industry, namely Sauvignon blanc, Chardonnay, Pinotage, Cabernet Sauvignon, Merlot and Shiraz were used. The producing cellars were from four major South African wine producing regions, namely Stellenbosch, Paarl, Robertson and Worcester. The data captured made a significant contribution to the establishment of the Aroma Project Database. Univariate statistics showed wide variations in the chemical composition of the wines. Red wines were generally characterised by high levels of higher alcohols and white wines by high levels of esters. Most of the differences between vintages were cultivar dependent and phenological differences between cultivars were suggested as a possible cause. Fusel alcohols, iso-acids and esters of fusel alcohols were particularly responsible for differences between red wines. A combination of fatty acids and higher alcohols were responsible for differences between production regions. However, using univariate statistics alone was limited in identifying characteristic features of the chemical composition of the wines. In order to explore the correlations between the volatile components, FTMIR spectra and nonvolatile components the data were further investigated with multivariate data analysis. Principal component analysis was successfully employed to distinguish between wines of different vintages and cultivars. The role of the volatile composition was more influential in the separation of vintage and red wine cultivar groupings than the non-volatile components or the FTMIR spectra. Almost all the individual volatile components contributed to the separation between the vintages and cultivars, thereby highlighting the multivariate nature required to establish the distinguishing features pertaining to each of these categories. The FTMIR spectra and the non-volatile components were more important than the volatile components to characterise the differences between the white cultivars. It was not surprising that both the volatile components and the FTMIR spectra were needed to distinguish between both red and white cultivars simultaneously. It was of interest the full spectrum, including all wavenumbers were required for a powerful classification model. This finding supports the initial expectation that the non-selective but information rich signal captured in the FTMIR spectra is indispensable. No distinction could be made between the production regions, which was not surprising since the wines used in this study was not of guaranteed origin. Furthermore, no clear correlation could be established between the chemical composition or the FTMIR spectra and the quality ratings of the wines. Limitations in the dataset were pointed out that must be taken into account during further investigations in the future. The liquid-liquid extraction method used during the analysis of the volatile components was evaluated for precision, accuracy and robustness. Generally good precision and accuracy were observed. There were slight indications of inconsistencies in the recoveries of analytes between the red and white wine matrices. Certain parameters of the protocol, namely sample volume, solvent volume, sonication temperature and sonication time, were identified as factors that had a major influence on quantification. The results obtained in this study made a major contribution towards establishing this technique for routine GC-FID analysis in our environment. Due to the high sample throughput in wine laboratories, the use of rapid quantitative analytical methods such as FTMIR spectroscopy is becoming increasingly important. Enzymatic-linked spectrophotometric assays and high performance liquid chromatography (HPLC) methods were evaluated for their suitability to serve as reference methods for optimising and establishing FTMIR calibrations for glucose, fructose, malic acid, lactic acid and glycerol. Pigmented and phenolic compounds were identified as sources of interference in the determination of organic acids in red wines with both enzymatic assays and HPLC. The use of fining treatments for the decolourisation of red wine samples was investigated. Activated charcoal was more efficient in terms of colour removal than polyvinyl polypyrrolidone (PVPP), but neither were compatible with the specific enzymatic method used in this study. Solid phase extraction (SPE), a method commonly used during sample clean-up prior to HPLC analysis of organic acids in wine, and PVPP fining were evaluated as sample preparation methods for HPLC analysis to optimise the quantification of organic acids in red wine. Four different types of SPE cartridges were evaluated and the SPE method was optimised in order to recover the maximum amount of organic acids. However, low recoveries, in some instance less than 50%, for the organic acids in wine were reported for the optimised SPE method. In this respect one was the worst. On average, excellent recoveries were observed for the organic acids using the PVPP method that were in excess of 90%. This method therefore provides a very valuable and simple alternative to SPE for sample-cleanup prior to HPLC analysis. One aspect that still needs to be investigated is the reproducibility of the method that should still be optimised. In general, enzymatic analysis was more suitable for the determination of glucose and fructose, while HPLC analysis were more suitable for the quantification of organic acids. Efficient glycerol quantification was observed with both enzymatic and HPLC analysis, although a lower measurement error was observed during the HPLC analysis. Apart from reliable reference methods, successful FTMIR calibrations also rely on the variability present in the reference sample set. The reference sample set used to establish FTMIR calibrations must ideally be representative of the samples that will be analysed in the future. Commercial, or so-called global, FTMIR calibrations for the determination of important wine parameters were evaluated for their compatibility to a South African young wine matrix. The prediction pH, titratable acidity, malic acid, glucose, fructose, ethanol and glycerol could be improved by establishing a brand new FTMIR calibration, thereby clearly indicating that the South African young wine matrices were significantly different from the samples of European origin that were used to establish the commercial calibrations. New preliminary calibration models were established for a young wine sample matrix and were validated using independent test sets. On average the prediction errors were considered sufficient for at least screening purposes. The effect of wavenumber selection was evaluated. Relatively successful models could be established for all the compounds except glucose. Wavenumber selection had an influence on the efficiency of the calibration models. Some models were more effective using a small amount of highly correlated wavenumbers, while others were more effective using larger wavenumber regions. Preliminary FTMIR calibration models for the screening of volatile compound groups in young wines were evaluated. Compound groups were compiled based on chemical similarity and flavour similarity. Good linearity were observed for the “total alcohol”, “total fatty acids”, “esters” models while an interesting polynomial trend was observed for the “total esters” model. Relatively high prediction errors indicated the possibility of spectral interferences, but the models were nevertheless considered suitable for screening purposes. These findings are a valuable contribution to our environment where fermentation flavour profiles must often be examined. The important role sound and validated analytical methods to generate high quality analytical data, and the subsequent application of chemometric techniques to model the data for the purpose of wine characterisation has been thoroughly explored in this study. After a critical evaluation of the analytical methods used in this study, various statistical methods were used to uncover the chemical composition of South African young wines. The use of multivariate data analysis has revealed some limitations in the dataset and therefore it must be said that wine characterisation is not just reliant on sophisticated analytical chemistry and advanced data analytical techniques, but also on high quality sample sets.

Le projet concerne la culture et le rôle social du vin français en Pologne entre la moitié de XVIIe et le début du XIXe siècle. Le but de ce travail est la présentation du procès de réception, de différentes formes de perception et de rôle social du vin dans le pays qui n’appartient pas à la zone de la culture de vin.Le XVIIIe siècle, c’est le temps des grands changements sociaux. Les changements des attitudes, de l’aspiration, de la sensibilité et des façons de communication sont les symptômes de la révolution de consommation. Les valeurs contemporaines d’économies chrétiennes se mettent à la négociation. C’est ce phénomène de la consommation qui provoque leur remplacement par l’égalitarisme et l’individualisme. À partir des informations concernant la vente, la consommation et la production de vin on peut montrer les modifications de la société en Pologne.Ce n’est pas que la société qui est soumise aux changements, mais si dynamiquement se varie le vin. Les nouvelles méthodes de production et de conservation apparaissent. Elles facilitent l’exportation non seulement de seule boisson, mais également de mode, de goûts et de culture matérielle liée à cette boisson. Les goûts de dîneurs ont évolué ensemble avec les ustensiles et la façon de laquelle le vin a été servi à la table – française ou polonaise.L’observation de l’influence du vin, si important élément de la culture française, sur la création des goûts des Polonais et leurs imaginations liées avec France et les Français, s’inscrit identiquement dans l’idée de la coopération franco – polonaise et donne les chances d’apparition d'influence mutuelle de deux cultures. / The project concerns the cultural and social role of French wine in Poland from the middle of the 17th to the beginning of the 19th century. The aim of this work is to demonstrate the process of reception, different forms of perception and social role of wine in a country not belonging to the wine culture sphere.The 18th century is a time of major social transformations. Changes in attitudes, aspirations, sensitivity and ways of communicating are signs of a consumer revolution. Old Christian principles are becoming to be negated and it is the phenomenon of consumerism which replaces them with egalitarianism and individualism. The analysis of information regarding the sale, consumption and production of wine helps to demonstrate the transformation of the Polish society.Apart from society, the wine itself also changes dynamically, with the appearance of new methods of its production and preservation enabling the export of not only the drink itself, but also of the fashion, taste and material culture connected with it. On its way from the cellar to the table, wine is accompanied by objects which become the inseparable elements of the drinking culture. The glasses and ways of serving wine evolve together with the taste of the banqueters.Research in the influence of wine on the development of Poles’ taste and their image of France and the French is naturally compatible with the idea of Polish-French cooperation and provides an opportunity to demonstrate the mutual influence of the two cultures.

This research investigated yeast populations and diversity during pre-fermentation cold maceration and alcoholic fermentation of Vitis vinifera L. cv. Pinot noir grapes from a commercial vineyard (Dayton, OR). Fermentations were conducted at the Oregon State University research winery in 100 L tanks while grapes from the same vineyard lot were fermented at a commercial winery. Samples were taken daily during pre-fermentation maceration (9°C) and alcoholic fermentation (27°C) and plated on WL and lysine media to determine Saccharomyces and non-Saccharomyces populations and diversity. Total non-Saccharomyces populations increased from 1 x 10³ cfu/mL to 1 x 10⁵ cfu/mL during pre-fermentation cold maceration and reached a maximum of 1 x 10⁷ cfu/mL during alcoholic fermentation. Thirteen distinct yeast species were tentatively identified based on appearance on WL media and were initially screened for β-glucosidase activity using 4-methyllumbelliferyl-β-D-gluconopyranoside (4-MUG) plates. The identity of the isolates screening positive for β-glucosidase activity was determined by sequence analysis of the D1/D2 domain of the 26S rDNA gene. The five isolates identified were Metschnikowia pulcherrima, Hanseniaspora uvarum, Kluveromyces thermotolerans, and two Saccharomyces cerevisiae isolates. β-glucosidase activity was further characterized and quantified using a liquid media representing grape must conditions (pH 3.5, 20° Brix) at two temperatures (25°C and 8°C). While increasing sugar concentration suppressed the β-glucosidase activity of H. uvarum (-99%), β-glucosidase activity still remained relatively high for M. pulcherrima, S. cerevisiae isolate 1, and S. cerevisiae isolate 2. At 8°C, β-glucosidase activity was reduced for M. pulcherrima compared to activity at 25°C, but activity increased for K. thermotolerans, S. cerevisiae isolate 1, and S. cerevisiae isolate 2. The yeast isolates possessing β-glucosidase activity were used in fermentations of Vitis vinifera L. cv. Pinot Noir grapes. The grapes were treated with high hydrostatic pressure (HHP) to inactivate naturally occurring yeast and bacteria. All yeast isolates grew during pre-fermentation cold maceration (7 days at 9°C) and populations increased 3 to 4 logs. Following pre-fermentation cold maceration, all ferments were warmed to 27°C and inoculated with S. cerevisiae RC212. Alcoholic fermentations were all complete within eight days and after pressing wines were analyzed for volatile aroma compounds by SPME-GC-MS. The presence of different yeast isolates during pre-fermentation cold maceration resulted in wines with unique aroma profiles. Ethyl ester concentrations were highest in the wine that did not undergo a pre-fermentation cold maceration, while concentrations of branch-chained esters were higher in the treatments with yeast present during pre-fermentation cold maceration. Pre-fermentation cold maceration with yeast isolates demonstrating β-glucosidase did not affect the concentration of β-damascenone or β-ionone. Wines that had undergone pre-fermentation cold maceration with S. cerevisiae isolate 1, S. cerevisiae isolate 2, and a combination of all isolates resulted in over twice the concentration of β-citronellol over wines that did not undergo a pre-fermentation cold maceration. / Graduation date: 2013

Until the introduction of the trade liberalization initiatives of 1989, the wine producers of British Columbia appeared to have operated in an environment that fostered less than competitive behaviour. Two factors in particular may have been responsible for creating such an environment: (1) the structure of the industry was inherently oligopolistic; and (2) protection from foreign competition was afforded by the British Columbia government in the form of a wine policy that effectively created non-tariff trade barriers against foreign wine producers. This study econometrically tests the hypothesis that British Columbia wine producers behaved non-competitively during the years 1957 to 1986. A model of the British Columbia wine industry is developed and used to estimate the degree of non-competitive pricing behaviour in the industry, and tests are undertaken to determine whether the estimate of behaviour is consistent with competitive or with other well known behavioral specifications. the main structural components of the industry are described in a model of oligopolistic behaviour using a linear system of equations, in which both demand and pricing equations appear. The parameters which affect each of these equations are estimated using the appropriate estimation technique. The econometric results, and the subsequent statistical tests, support the hypothesis that the domestic wine industry in British Columbia operated in a non-competitive manner between 1957 and 1986. Specifically, the hypothesis of competitive behaviour is statistically rejected, whereas, the hypotheses of Cournot and collusive-type behaviour could not be rejected. These results suggest that British Columbia consumers may have been sacrificing to firms at least a portion of the surplus they would have obtained in a perfectly competitive industry. In addition, it appears that the wine policy of the provincial government helped create a non-competitive industry that will likely have difficulty competing in today's global market for wine.
