Banques de données biologiques annuelles par terroir et optimisation des itinéraires culturaux

Abstract

En complément des études sur les caractéristiques édaphiques et paysagères du milieu (Dolédec, 1995), la caractérisation de la physiologie de la vigne et du parasitisme au cours de son cycle végétatif représente une composante essentielle de connaissance et de gestion des terroirs.

L’examen des chroniques et données disponibles dans ce domaine souligne une importante variabilité entre années et pour une même année entre les terroirs, le climat jouant un rôle essentiel dans la structuration de ces fluctuations. L’étude du climat à deux échelles, régionale et mésoclimatique (Panigai, Langellier, 1992), s’avère en conséquence indispensable pour développer des outils d’aide à la décision (modèles) qui utilisent des données climatiques en entrée, pour guider le viticulteur dans certains choix culturaux. Ce travail nécessite une phase préalable de conjrontation temporelle et de validation spatiale des informations modélisées par rapport aux observations de terrain. La constitution sous-jacente de banques de données biologiques annuelles par terroir qui sont à créer doit être le fruit de synthèses regroupant des références de réseaux expérimentaux et d’enquêtes conduites auprès des professionnels. Le mildiou, pour le thème parasitaire, et le poids des grappes, pour la physiologie, sont présentés pour illustrer cette démarche.

Impact of winemaking processes on wine polysaccharides, improving by qNMR

Today the knowledge in terms of molecular composition of the colloidal matrix is ​​not enough in order to control its stability, according to the number of winemaking and wine stabilization processes. The physico-chemical processes during the winemaking change the composition and quantity of wine macromolecules. The goal today is to determine which analytical techniques will allow to discriminate these winemaking processes in order to better understand their impact on colloidal matrix stability as well as which molecules are responsible for its instabilities. METHODS: Wines obtained after conventional winemaking were subjected to different fining and chemical stabilization treatments. Different methods were used to investigate the wine macromolecular composition and stability after chemical stabilization, including quantitative and qualitative analyzes of total soluble polysaccharides by extraction under acidified ethanol, and by size exclusion separation as well as qNMR metabolomics. RESULTS: Observation of a slight difference at the quantitative level using classical analysis between the winemaking processes was observed as well as a strong discrimination by qNMR metabolomics.

Development of novel drought-tolerant grape cultivars from Monastrell: enhancing anthocyanin and flavonol content under elevated temperatures

The ongoing challenge of climate change is driving the need for novel oenological approaches aimed at finding effective environmental solutions.

Grape stems as preservative in Tempranillo wine

SO2 is the most widely used preservative in the wine industry. However, there are several drawbacks related with the use of SO2 in wine such as its toxicity and the unpleasant odor in case of excess.

Innovations on red winemaking process by ultrasound technology

High power ultrasound has been recently recognized one of the most promising technologies in winemaking processes, especially after the recent OIV resolution, concerning the application of ultrasounds on crushed grapes to promote the extraction of skin compounds.

Effect of Quercus Alba oak barrels from different forests on the polyphenolic composition of Tempranillo red wines

The species and origin used for red wine oak aging determines the physiological composition of the wood and thus the finished wines. In America, oak is grown primarily in the states of Virginia, Missouri, Kentucky, Oregon, Ohio, Minnesota, Wisconsin and California. The aim of this study was to analyze how the choice of barrels made with Quercus Alba oak from different geographic areas of the United States (Missouri, Kentucky, Ohio and Pennsylvania) influences the polyphenolic composition of Tempranillo red wines.
