Climat et sol: critères d’évaluation et effets sur le comportement de la vigne

Abstract

Le zonage viticole aborde en premier lieu la caractérisation des macroclimats aux échelles des grandes régions, pays, continents ou monde (géoviticulture). La méthodologie de caractérisation climatique et les premières applications au niveau des zones climatiques viticoles, sont présentés par Jorge Tonietto et Alain Carbonneau dans l’article du même ouvrage “Systèmes de Classification Climatique Multicritères (CCM) Géoviticole”, suite aux publications de Tonietto et Carbonneau, 1998a et 1999, et de Tonietto, 1999. Le présent article s’adresse aux échelles du terroir (interaction mésoclimat x sol/sous-sol), de la petite région ou de la parcelle.
Dans une première partie un rappel sera fait de l’influence du climat sur un cycle végétatif moyen de la vigne. Dans une seconde partie les méthodes de caractérisation des sols seront résumées, puis la méthodologie du bilan hydrique potentiel du sol sera approfondie. Dans une troisième partie, sur la base du réseau de terroirs pour le cépage Syrah dans le midi de la France, les principaux éléments de la typicité des vins seront mis en relation avec des variables du climat, du sol et du comportement de la vigne.

Nucleophilic fraction to estimate the antioxidant activity of inactivated yeast derivates

Oxidation in wine is mostly related to the Michael addition of nucleophiles on two quinones formed from the oxidation of ortho-diphenols. In wine this mechanism is responsible for the increase of the yellow hue and aroma loss. Glutathione exerts its antioxidant activity throughout its competitive addition onto quinones, but many other compounds can have the same behavior: sulfanyl
compounds, amino acids, etc. Addition of yeast derivates during the winemaking process can increase the level of those nucleophilic compounds and then confer to the wine a higher resistance

INFLUENCES OF SO2 ADDITION AND STORAGE CONDITIONS IN THE DETERMINATION OF MEAN DEGREE OF POLYMERIZATION OF PROANTHOCYANIDINS IN AGED RED WINES

The structural diversity is one of the most remarkable characteristics of proanthocyanidins (PA). Indeed, PA in wines may vary in the B-ring and C-ring substitutes, the C-ring stereochemistry, the degree of polymerization (DP) and the linkage between the monomers. Knowing in detail the structural characteristics of the PA of a wine can help us to understand and modulate several sensorial characteristics of the wine, such as color, antioxidant properties, flavor, and mouthfeel properties. In the last years was discovered and confirmed the presence of sulfonated monomeric and oligomeric flavan-3-ols in wine [1], as well as was pointed out their importance in wine quality [1,2].

Can early defoliation improve fruit composition of Tempranillo grapevines in the semi-arid terroir of Utiel-Requena, Spain?

Early defoliation has been found a useful tool to reduce cluster compactness and to improve fruit composition in vigorous sites of different viticultural areas. Our objective was to test the usefulness

Oxygen consumption by diferent oenological tanins in a model wine solution

INTRODUCTION: Oenological tannins are widely used in winemaking to improve some characteristics of wines [1] being the antioxidant properties probably one of the main reasons [2]. However, commercial tannins have different botanical sources and chemical composition [3] which probably determines different antioxidant potential. There are some few references about the antioxidant properties of commercial tannins [4] but none of them have really measured the direct oxygen consumption by them. The aim of this work was to measure the kinetics of oxygen consumption by different commercial tannins in order to determine their real capacities to protect wine against oxygen. MATERIAL AND METHODS: 4 different commercial tannins were used: T1: condensed tannin from grape seeds, T2: gallotannin from chinese gallnuts, T3: ellagitannin from oak and T4: tannin from quebracho containing condensed tannins and ellagitannins.

Beneficial effects of moderate consumption of Teran red wine on blood lipid profile: a preliminary study on healthy volunteers

Moderate wine consumption may impact several human health aspects, among others as a result of phenolic compounds present in wine and their bioactive properties. The aim of this study was to determine whether six weeks of daily, moderate Teran red wine consumption affects the levels of total cholesterol, high-density lipoprotein cholesterol – HDL, low-density lipoprotein cholesterol – LDL, and triglycerides. Sixty-eight healthy adults (46 women and 22 men) aged 25-64 years voluntarily agreed to participate in the study.
