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.

Text mining of wine reviews to investigate quality markers of ‘Nebbiolo’ wines from Valtellina

In Valtellina zone (north Italy), the winemaking of ‘Nebbiolo’ grapes leads to the production of two main wine types: classic red wines from fresh grapes, usually classified as Valtellina Superiore DOCG (mandatory oak aging) or Rosso di Valtellina DOC, and the Sforzato di Valtellina DOCG, which is produced using withered grapes according to traditional product specification and subjected to mandatory oak aging process. The withering process influences grape chemical composition and, in turn, the wine sensory profile, which is strongly linked to the wine quality and typicity perceived by consumers.

Using GIS to assess the terroir potential of an Oregon viticultural region

Deciding to grow grapes in Oregon is complex issue due to our diverse geography, climate, and relatively short history of grape growing. For any potential grape grower, vineyard site selection is the single most important decision they will face.

Gas chromatography-olfactometry characterization of corvina and corvinone young and aged wines

AIM AND METHODS: Corvina and Corvinone are the two main grape varieties used in the production of Valpolicella, Recioto and Amarone, top-quality red wines in north-eastern Italy. This work aimed at determining the aroma composition of Corvina and Corvinone experimental wines and identify the main aroma compounds contributing to the aroma characteristics of Corvina and Corvinone monovarietal wines. Five Corvina and five Corvinone wines were studied, the grapes coming from five different vineyards in Valpolicella. Volatile compounds were extracted by SPE and identified and quantified by gas chromatography-mass spectrometry (GC-MS), whereas their aroma impact was determined by gas chromatography- olfactometry (GC-O).RESULTS: Based on the GC-MS-O analysis, 95 odor zones were detected, from which 68 compounds were successfully identified. Using the criterion of a value higher than 30% in modified frequency (MF %), 51 compounds were selected and grouped according to odor similarity. Compounds with values below 30% were discarded.

Impact of changing climatic factors on physiological and vegetative growth

Scientific information on grapevine response to predicted levels of climate parameters is scarce and not sufficient to properly position the Wine Industry for the future. It is critical that the combined effects of increased temperature and CO2 on grapevines should be examined, without omitting the important link to soil water conditions. The purpose of this study is to quantify the effects of envisioned changes in climatic parameters on the functioning and growth of young grafted grapevines under controlled conditions, simulating expected future climate changes. Scientific knowledge of precisely how the newly-planted grapevine will react morphologically, anatomically and physiologically (at leaf, root and whole plant level) to the expected changes in important climatic parameters will enable producers to make better-informed decisions regarding terroir, cultivar and rootstock choices as well as the adaptation of current cultivation practices.

Redwine project: how to valorize CO2 and effluents from wineries in vineyards and winemaking with microalgae biomass

Global warming due to greenhouse gases (GHG) has become a serious worldwide concern. The new EU green deal aims to achieve GHG emissions reduction by at least 55% by 2030 and a climate neutral eu economy by 2050. The deal strongly encourages GHG reducing measures at local, national and european levels. The redwine project will demonstrate the technical, economic and environmental feasibility of reducing by, at least, 31% of the CO2 eq.
