Variabilité spatiale du gel printanier dans le vignoble champenois : application au zonage climatique

Abstract

Dans le vignoble de Champagne, les gelées de printemps sont à l’origine de variations importantes du volume de récolte qui sont très pénalisantes pour le commerce. Cette variabilité se traduit à la fois dans le temps (années sans gelée alternant avec des années avec de fortes gelées) et dans l’espace. Certains secteurs du vignoble sont en effet statistiquement plus gélifs que d’autres, mais, chaque année, aucune commune ne peut se considérer à l’abri de cet accident climatique. L’objectif de l’étude est précisément d’analyser la répartition spatiale du gel et d’en déterminer les principaux mécanismes, liés à la topographie des coteaux, leur orientation mais aussi aux variables météorologiques régionales.

Exogeneous C-S lyase enzyme, a potential tool for thiol enhancement in wine or beer?

Varietal thiols are considered for years as key aroma compounds in many wines. Their main origin is the cleavage during alcoholic fermentation of S-conjugate precursors present in grapes and musts, even if the levels of precursors already identified struggle to completely explain the levels of thiols found in wine.

Comparison between non-Saccharomyces yeasts for the production of Nero d’Avola wine

Wine production with non-Saccharomyces yeasts is getting larger application due to the positive impact of these yeasts on wine composition. Previous studies showed notably differences in chemical composition of Merlot wines obtained with Torulaspora delbrueckii.

Saccharomyces cerevisiae – Oenococcus oeni – Lactiplantibacillus plantarum: focus on malolactic fermentation during production of Catarratto and Riesling white wines

The increasing interest in enhancing groundbreaking sensory profile of wines determined the need to select novel strains of lactic acid bacteria (LAB). Metabolic processes characterizing malolactic fermentation (MLF) lead to the production of several organic compounds that significantly impact the oenological and sensory characteristics of wines.
