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.

Comparison of aroma-related compounds of carbonic maceration and traditional young red winemaking in case of Merlot by means of targeted metabolomic approach

Winemaking decisions and techniques are known to affect the final aromatic composition of red wines. Winemakers put a constant effort into the improved controlling of vinification procedures to achieve better quality. Anyway an increased customer’s demand for uniqueness is often forcing them to adjust and offer new and new interesting products. To support the producers, an improved knowledge on aromatic potential as affected by classical and alternative strategies is needed.

Exploring changes in browning kinetics, color, and antioxidants due to dealcoholization of wine

The global consumer demand for low or non-alcoholic wine is growing steadily in recent years, driven by health concerns, religious beliefs, and personal taste preferences etc.. Consequently, the removal of alcohol from wine can significantly alter its chemical and sensory properties, including color, aroma, and taste, which make a significant challenge for consumer to accept these products. Ethanol plays a crucial role in various chemical reactions and interactions that contribute to the development of wine’s characteristics.

Importanza del monitoraggio micro-meteorologico nella caratterizzazione del terroir

Le variabili meteorologiche e micro-meteorologiche ricoprono un importante ruolo sulla risposta vegeto-produttiva della vite e di conseguenza sulla qualità delle produzioni. Utilizzando una rete wireless di sensori sono stati monitorati i parametri meteorologici e micro-meteorologici di 4 vigneti del territorio toscano e in differenti condizioni di gestione agronomica.

Weather classification over the Western Cape (February, 1996 – 2000) and viticultural implications in the Stellenbosch wine district

Une étude préliminaire des situations météorologiques journalières a été réalisée pour l’Afrique du Sud et pour les mois de février (période de maturation des raisins dans la Province occidentale du Cap), à l’image de la classification synoptique réalisée aux latitudes tempérées en France (Jones & Davis, 2000), afin d’étudier les relations entre le climat et la viticulture à des latitudes plus basses.

Induction of polyphenols in seedlings of Vitis vinifera cv. Monastrell by the application of elicitors

Contamination problems arising from the use of pesticides in viticulture have raised concerns. One of the alternatives to reduce contamination is the use of elicitors, molecules capable of stimulating the natural defences of plants, promoting the production of phenolic compounds (PC) that offer protection against biotic and abiotic stress. Previous studies on Cabernet-Sauvignon seedlings demonstrated that foliar application of elicitors methyl jasmonate (MeJ) and benzothiadiazole (BTH) increased proteins and PC involved in grapevine defence mechanisms. However, no trials had been conducted on Monastrell seedlings, a major winegrape variety in Spain.
