Méthode et outils de valorisation des terroirs en cave coopérative

Abstract

[English version below]

Depuis le début des années 90, les vignerons des Caves Coopératives de l’Appellation “Côtes du Rhône” se sont penchés, au sein des structures de réflexion du Syndicat Général, sur deux axes de réflexion:
– Détermination des critères de sélection et de rémunération différenciée des apports de vendange;
– Organisation des sélections de vendanges sur la base des terroirs afin d’augmenter quantitativement le potentiel de sélection au sein de l’unité de production.
Une étude conjointe de ces deux axes de préoccupations a conduit le service technique de l’A.O.C. à mettre au point une méthodologie de caractérisation des apports de vendange à la parcelle ainsi qu’à la réception au chai de vinification qui permette d’optimiser quantitativement par une meilleure organisation et qualitativement par une adéquation du processus de vinification aux caractéristiques de la matière première, sa transformation et sa commercialisation. Un logiciel a été conçu et développé spécifiquement pour la mise en œuvre de la méthodologie.
Cette démarche qui permet une véritable transparence entre l’amont viticole et la valorisation au sein de l’unité de vinification peut constituer un outil très efficace dans le cadre d’une démarche de certification d’entreprise.

Since the beginning of the decade, the wine-growers of the AOC Côtes du Rhône cooperatives have concentrated through their Syndicates development committee, on two main areas of research:
– Identification of criteria for the selection of grapes and a sliding scale of remuneration according to the quality of the transportation of the harvest.
– Organization of harvest selection based upon the concept of terroir, so as to increase on a quantitative level, the options for selection at the heart of the production site.
Research on these two important themes has led the AOC technical division to divide a method for assessing harvest transport both in the vineyard and at the vinification site. This will permit better winemaking and marketing, on a qualitative level by ensuring the best vinification methods are used for the grapes concerned, and on a quantitative level, through better organization.
A computer programme has been specifically designed for the development of this method. This process allows complete transparency between vineyard and vinification center and may constitute a highly effective tool for a company wishing to obtain certification of their products.

Counting grape bunches using deep learning under different fruit and leaf occlusion conditions

Yield estimation is very important for the wine industry since provides useful information for vineyard and winery management. The early yield estimation of the grapevine provides information to winegrowers in making management decisions to achieve a better quantity and quality of grapes. In general, yield forecasts are based on destructive sampling of bunches and manual counting of berries per bunch and bunches per vine.

Impact of nitrogen addition timing on the synthesis of fermentative aromas in alcoholic fermentation

Among the different compounds present in the must, nitrogen is an essential nutrient for the management of the fermentation kinetics but it also plays an important role in the synthesis of fermentative aromas.

Elucidating white wines peptides: An analytical breaktrough

The chemistry of wine is particularly complex due to biochemical and chemical interactions that significantly modify its organoleptic characteristics and stability over time. Aging on lees is a well-known practice during which various compounds are released, ensuring wines oxidative stability and its overall sensory quality [1,2].

Management of grapevine water status with the DSS Vintel® provides evidence of sustainable irrigation strategies while maintaining wine quality of Pinot gris in Friuli-Venezia Giulia region, NE italy

Deficit irrigation strategies can be valuable means to improve grape quality while saving important amounts of water. A simple way to use deficit irrigation can be based on irrigating a vineyard with a determined level of crop evapotranspiration. Using a precise physiological parameter indicating water status, irrigation could be managed to maintain a specific pre-dawn leaf water potential.

Red wine astringency: correlations between chemical and sensory features

Astringency is a crucial sensory attribute typically described as the drying and/or puckering sensation occurring after the consumption of tannin-rich foods and beverages. In this study, thirty-seven red wines from different varieties, origins and styles were evaluated, analyzing both chemical and sensory features. Principal Component Analysis was used for dimensionality-reduction and for correlating selected chemical parameters against astringency. The results showed that tannin content was the most important chemical parameter influencing overall astringency but more clearly the dryness sub-quality, followed by pH, titratable acidity and alcohol content.
