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.

Effects of different crop load and pruning aplications on vi̇ne growing, grape yi̇eld and quality parameters of early sweet (Vitis vinifera L.) grape variety

It is important to examine the yield quality elements of table grape varieties. There are great differences in winter and summer pruning of the early sweet grape variety. For this reason, in the study, the effects of different crop loads and pruning processes on grape yield, quality characteristics and vine development in the early sweet (vitis vinifera L.) Grape variety were investigated.

POTENTIAL OF PEPTIDASES FOR AVOIDING PROTEIN HAZES IN MUST AND WINE

Haze formation in wine during transportation and storage is an important issue for winemakers, since turbid wines are unacceptable for sale. Such haze often results from aggregation of unstable grape proteinaceous colloids. To date, foreseeably unstable wines need to be treated with bentonite to remove these, while excessive quantities, which are often required, affect the wine volume and quality (Cosme et al. 2020). One solution to avoid these drawbacks might be the use of peptidases. Marangon et al. (2012) reported that Aspergillopepsins I and II were able to hydrolyse the respective haze-relevant proteins in combination with a flash pasteurisation. In 2021, the OIV approved this enzymatic treatment for wine stabilisation (OIV-OENO 541A and 541B).

Comparison between satellite and ground data with UAV-based information to analyse vineyard spatio-temporal variability

Currently, the greatest challenge for vine growers is to improve the yield and quality of grapes by minimizing costs and environmental impacts. This goal can be achieved through a better knowledge of vineyard spatial variability. Traditional platforms such as airborne, satellite and unmanned aerial vehicles (UAVs) solutions are useful investigation tools for vineyard site specific management.
