Miranda, Julie. "Recherche des déterminants moléculaires de la permissivité des vins rouges vis-à-vis de Brettanomyces bruxellensis". Electronic Thesis or Diss., Bordeaux, 2023. http://www.theses.fr/2023BORD0465.
Texto completoOdours deemed harmful by the consumer and described as "stable", "horse sweat" or "burnt plastic" can be found in wines. The responsible molecules are volatile phenols, produced by a spoilage yeast: Brettanomyces bruxellensis. This species is particularly well adapted to the wine environment and can resists many stresses such as a high alcohol level, a low pH or high levels of SO2, more or less efficiently depending on the strain considered. Indeed, the species displays a very high genetic diversity, even at the scale of the Bordeaux vineyard.The main objectives of this thesis were (1) to evaluate the variability of the permissiveness among Bordeaux red wines regarding the contamination by different strains of B. bruxellensis, (2) to show a possible relationship between the chemical composition of wines and their permissiveness, using non-targeted metabolomic analyses, and (3) to study the effect of different fractions obtained from a difficult wine.The studied strains showed very different behaviors depending on the red wines considered. These differences can be linked to several factors such as the vintage, the winery, or the wine batch. Chemical composition analyses made it possible to rule out several compounds not involved in permissiveness but also to identify families of molecules that would reduce the vulnerability of certain red wines from the Bordeaux area

Texto completoThe fruity aroma of red wines is described by a wide range of descriptors, ranging from fresh fruits to ripe and jammy fruits, to candied fruits and prunes notes. The fruity quality of a red wine is characterized by notes of fresh and jammy red- and black-berry fruits. Although many sensory attributes are mentioned in the literature, knowledge regarding the qualitative fruity aroma of red wines in relation to their chemical composition still requires further investigation. However, at least one component of this fruity expression reflects perceptual interactions primarily involving esters, as well as other families of aromatic molecules. In recent years, changes in the fruity expression of Bordeaux red wines, characterized by the emergence of notes of cooked and dried fruits, have been reported and correlated with climate change. Thus, technicians in the wine industry and scientists emphasize the need to take precautions to preserve the fresh fruity aroma of Bordeaux red wines. One adaptation strategy involves introducing late-ripening grape varieties selected for their potentially suitable vegetative cycle under future climatic conditions into Bordeaux vineyard. This thesis proposes a better understanding of the fruity aroma of red wines derived from Bordeaux grape varieties, as well as those cultivated around the Mediterranean basin, simulating the future climatic conditions in Bordeaux. Through sensory approaches, it has been demonstrated that Bordeaux red wines exhibit similarities with red wines derived from grape varieties grown around the Mediterranean in terms of their fruity character. A detailed characterization of the contribution of volatile compounds of interest in the perception of fruity notes has been conducted. Perceptual interactions between compounds from the monoterpene and C13 norisoprenoid families, mixed with esters, have revealed the importance of these compounds in the perception of fruity notes. Finally, the addition of these volatile compounds to a red wine shows a decrease in cooked fruit notes and an increase in fresh black-berry fruits notes. This research opens up new perspectives in oenology, such as controlling the levels of these compounds of interest through various practices, as well as the potential introduction of "new" grape varieties into Bordeaux wine blends

Texto completoBordeaux wine, through its widespread presence in an original presentation, that of "wine growing château" sparks debate. First of all can a "château" be made into a Bordeaux model of wine-growing and producing ? in order to answer this question, we postulate that this specific set up does in fact testify to a localised model which is indirectly analysed in a more classical analysis involving the observation and physical description of a Bordeaux wine industry between 1980 and 2003. There are three main objectives: to better understand the originality of the notion compared with other types of viticulture activity (commercialisation by a trade mark or a grape variety); to carry out an update on the dynamics of Bordeaux wine-growing and producing since the latest major geographical studies on the question, stopping on the eve of the 1980's; during this stage, to validate or invalidate the initial premise. After this, the premise having been validated, the significance of the aforesaid, the significance of the aforesaid model will be examined. It is in this part that the "thesis", in the strict sense of the word will be developed. By focusing on the cultural logic of each of the different historical actors in Bordeaux vineyard a parallel can be drawn between the model in question and the French bourgeois culture, so as to show that links exist between an ideology and the way in which an activity is organised. Here again there are three objectives: to put forward a possible interpretation of this model of viticulture; to bring out its identity; to assess the importance of the development and protection of certain wine-growing areas that could indeed be designated as part of the cultural heritage of Bordeaux

Texto completoBetween 1650’s and the end of Ancien Regime, the vineyard of Bordeaux knew a new period of development and transformations, related to the prosperity of the city of Bordeaux as well as to the important European demand in wine. The vineyard of Sauternais took part largely in the implementation of a wine production recognized for its quality as much as for its identity. Voluntarily localised, the study of the vineyard of Sauternes’ area makes it possible to closely understand the changes of a productive space, to see their mechanisms, their methods and their limits over one and half century of study. Production and trade of the wine structured spaces as much as rural society. Indeed, even if the mixed farming remained very present, the vine governed a good part of the economic activities: it animated widely the circulation of the landed properties and transformed little by little the traditional seigneurial structures into wine castles. The analysis of the improvement of the wine making and farming techniques shows a socially differentiated diffusion, often introduced by elites then transmitted or imposed to the small world of the vineyard. Besides, even if the nearness with the town of Bordeaux played a very important role in the development of this vineyard, thanks to the conveniences of the river transport and to the investments of the urban nobility and bourgeoisie, it is advisable to underline the local economic dynamics. This study on small scale thus allows to interrogate rural world in depth, by pointing the originality of this wine growing region. But it also offers the occasion to show that it is not so different from the other countrysides of the kingdom and that it fundamentally belonged to the rural world of Ancien Regime

Texto completoSaccharomyces cerevisiae is the main actor of wine fermentation but still little is known about the factors impacting its distribution in the vineyards. Bordeaux region, by its history and its appellations, is one of the regions of interest to study S. cerevisiae diversity. A total of 2422 isolates of S.cerevisiae sampled from grapes and spontaneous fermentation tanks during two consecutive years were analyzed by 15 to 17 microsatellite markers. A very high genetic diversity is demonstrated, greater in conventional farming system than in organic one. The type of farming system weakly influences the population structure of S.cerevisiae in the vineyard. The appellation and the wine estate significantly impact the population structure, without appearance of diversity gradients, but our analyses reveal important connections from the Pessac-Léognan to other Bordeaux appellations, especially to the Medoc. Bidirectional strong flows are highlight between the vineyard and the cellar compartments as illustrated by the presence of 25% of commercial related strains in the vineyard, due to the unexpected return of strains through cellar to the vineyard, while a flow of similar magnitude is observed between the vineyard and the cellar. The presence of common ancestral populations in old (over 20 years) and recent samples showed population stability over the long-term at an appellation scale. A temporal succession of cellar populations was highlighted that could be link with the implementation of the Pied de Cuve method through successive inoculations

Texto completoOrganic viticulture, which emerged in France after the Second World War and long remained marginal, has been booming for ten years now. The craze for organic wines, in terms of both production and consumption, is driven by the increase of environmental concerns regarding the use of pesticides, and by growing criticism of the standardization of wine manufacturing methods. Yet, organic viticulture is still struggling to emerge in the wine sector as a relevant solution to these current issues. Its mixed results question the ability of stakeholders in wine territories to embrace organic viticulture. This thesis explores the spatial and temporal processes at work in the dissemination of organic viticulture in France, as a groundswell whose transformations go beyond environmental purposes. Organic viticulture addresses plural determinants, – economics, tastes, ethics, health – as symptoms of an overall renewal of the relationships between wine, viticulture and territory. It reflects the shifting aspirations of urban societies concerning wine, wineries and rural areas. The geographical analysis of its dissemination, scope and limitations reveals that organic viticulture is both the witness and the driving force of deep transformations in the wine world. The latter is analyzed within a broader framework of issues in French rural and wine geography, currently undergoing a major upheaval. The territorial approach of this research analyses the dissemination of organic viticulture through the lens of increasingly numerous and varied relationships between actors in vineyards. Our grid focuses on winemakers, considered the main drivers of the spread of organic viticulture and whose role is representative of the changing relationship between urban and rural areas. The study of practices, discourses and representations is at the center of our approach. The undergoing processes are analysed in the whole French vineyard. The specific study of two wine regions, the Bordelais and the Rhône Valley, captures the complex territorial dynamics of this dissemination
Fabre, Sandy. "De la synthèse de procyanidines à leur quantification dans les baies de raisins et le vin". Thesis, Bordeaux 1, 2009. http://www.theses.fr/2009BOR13891/document.
Texto completoFlavanols and their oligomers, procyanidins, are phenolics compounds biosynthetized in grapes, from which they are extrated during winemaking As they contribute so much to the organoleptics properties of the wine (color, bitterness and astringency), a better comprehension of their evolution during grapes maturation, winemaking and ageing of the wine is particulary important. Several procyanidines were obtained by a synthesis method which allows to control as well the interflavan regio- and stereoselectivity as the degree of oligomerization. This method was extended to the synthesis of galloylated procyanidins. The stage of coupling, which was a limiting stage of this synthesis, could be improved by the use of gold III catalysis. These compounds were then used as standards in order to identify and quantify them in grapes and wines by high performance liquid chromatography. The supramolecular properties of galloylated procyanidins were investigated by NMR DOSY. In parallel to these studies, a new indolic compound bearing a glucose moiety, has been identified and characterized for the first time in red wine

Thesis, Bordeaux 2, 2010. http://www.theses.fr/2010BOR21762/document.
Texto completoSkin grape maturation is a complex phenomenon, characterized by an important number of structural changes as well as by phenolic compounds accumulation (i.e. tannins). Despite their biological and organoleptic properties in fruit and wine quality, few studies report both tannins organization and localization in skin tissue. In skins, tannins may be more or less related with cellular components, modulating their extractability during winemaking process.Our work, based on biochemical, molecular and microscopic approaches reveals new data on skin tannins biosynthesis, localization and organization. Within this tissue, we highlighted the parietal tannins importance, we evidenced that their physicochemical characteristics depend among other structural changes on cell walls. Thus, this organization partially characterized the skin texture and affects fruit quality. To understand the evolution criteria for skin texture during grape berry ripening, sensory analysis and measurements by penetrometer proved to be relevant tools
