Incidence de la nature du sol et du cépage sur la maturation du raisin, à Saint Emilion, en 1995

Abstract

L’A.O.C. Saint-Emilion, une des plus prestigieuses du Bordelais, se situe sur la rive droite de la Dordogne en amont de Libourne. Le vignoble est implanté sur des formations géologiques du Tertiaire (Oligocène) et du Quaternaire, sur lesquelles se sont développés des sols très variés. De nombreuses études ont rendu compte de cette hétérogénéité et permis de mieux connaître le fonctionnement et les potentialités viticoles de ces sols (Duteau et al. 1981, Van Leeuwen, 1991).

Dans ce travail, nous avons étudié le comportement des deux principaux cépages noirs de la région, le Cabemet franc et le Merlot noir, sur trois sols : un sol graveleux (G), un sol à sous-sol très argileux (A) et un sol sableux avec une nappe d’eau à portée des racines (S). L’objectif a été de mieux connaître les interactions entre le sol et le cépage, afin de valoriser au maximum les potentialités du terroir par une adaptation judicieuse du cépage au type de sol. Nous présentons ici les résultats obtenus au cours du millésime 1995, qui seront comparés avec ceux obtenus en 1994.

Screening of hydroxytyrosol and tyrosine related metabolites in commercial wines by an UHPLC/MS validated method.

Hydroxytyrosol (HT) is a bioactive phenolic compound with antioxidant activity. Yeast synthetise tyrosol from tyrosine by the Ehrlich pathway which is subsequently hydroxylated to HT. The aim of the present work is to develop and validate an UHPLC–HRMS method to assess the metabolites involved in this pathway as well as to screen Spanish commercial wines for HT bioactive compound.

Potential application of indigenous Pichia kluyveri for enhanced wine aroma quality

Aims: In previous work, five indigenous Pichia kluyveri strains, GS1-1, FS-2-7, HS-2-1, C730 and C732, were isolated and selected from spontaneous fermented wines from Ningxia and Gansu. The aims of this study were to 1) evaluate resistance of these strains to environmental stressors that may restrict their growth and the progress of alcoholic fermentation; 2) Investigate their fermentation dynamics; 3) Characterise aroma profiles of Cabernet Sauvignon wines made from mixed cultures of P. kluyveri and Saccharomyces cerevisiae.

Exploring typicity in Nebbiolo wines across different areas through chemical analysis

“Nebbiolo” is a red winegrape variety well known to produce monovarietal wines in Piemonte, Valle d’Aosta, and Lombardia regions, taking part to 7 DOCG (Denominazione di Origine Controllata e Garantita) and 22 DOC (Denominazione di Origine Controllata) protected designations of origin (PDO) [1,2].

Influenza del sito di coltivazione nella espressione aromatica del Moscato liquoroso di Pantelleria

ln 1997, twenty six cultivation sites of cv. Muscat of Alexandria different for pedological conditions, altitude and exposition were selected through ail Pantelleria isle. ln each site, described and classified according to USDA Soil Taxonony and FAO Soil Classification methods, grapes, collected at technological ripening, were microvinificated, following a standard procedure which allowed to obtain the naturally sweet wine DOC Moscato di Pantelleria. Wines, five months after vinification, were analysed by gaschromatography.

Development, validation and application of a fast UHPLC-HRMS method for the analysis of amino acids and biogenic amines in wines and musts.

The amino acids in grape juice are an important nitrogen source for yeast during alcoholic fermentation. Additionally, certain AAs are precursors to some of the volatile compounds found in wine and overall
