Méthodologie pour application et valorisation des études de terroir dans les caves cooperatives des Côtes du Rhône (France)

Abstract

[English version below]

L’appellation d’origine contrôlée “Côtes du Rhône” se caractérise par une très forte implantation du mouvement coopératif. Afin de mieux exploiter le potentiel qualitatif de leurs terroirs, plusieurs coopératives élaborent des “cuvées terroir”, résultat des sélections de vendanges provenant de différents secteurs.
Le travail répond à la demande des professionnels pour approfondir la connaissance de la diversité de leurs terroirs, pour évaluer leur incidence sur la matière première et pour établir une démarche permettant de mieux gérer les sélections parcellaires.
La méthodologie proposée se déroule en trois étapes :
I. Caractérisation de la diversité des terroirs au sein d’une cave coopérative : cartographie des sols.
II. Evaluation du fonctionnement, essentiellement hydrique, des principaux sols et de leur incidence sur le comportement de la vigne et sur la composition du raisin. L’objectif est de dégager des indicateurs simples pour caractériser cette incidence.
III. Application pour les sélections “terroir” : ces outils sont testés ensuite pour la mise en place d’une sélection parcellaire au niveau de la cave.
Cette démarche a été appliquée sur différentes caves. A titre d’exemple, nous illustrerons cet article avec les résultats obtenus pour la cave de Rochefort du Gard.
La méthode présentée débute avec une étude de zonage. Elle se complète ensuite par une évaluation du potentiel de différentes unités de sol et, enfin, donne lieu à une application pratique pour améliorer la gestion des sélections de vendange dans un contexte professionnel bien précis, celui des caves coopératives.

Most of the “Côtes du Rhône” controlled appellation wine is produced by cooperative wineries. In order to make the best use of the qualitative potential of their “terroirs”, several cooperative wineries produce specific “cuvees terroir” with harvest selections from different districts.
This work is an answer to professionals’ needs to enhance the knowledge of their “terroirs” diversity, to evaluate their effects on grape berry composition and to work out a methodology to improve the management of harvest selections.
The proposed methodology is developed in 3 stages :
I. Characterisation of “terroirs” diversity of a cooperative winery area : maps of the soils.
II. Evaluation of the way the most important soils function, essentially for water and of the influence on vine behaviour and on grape berries composition. The aim is to look for simple tests explaining this influence.
III. Application to “terroir” harvest selections : the tests are then tried out to set up a harvest selection in the winery.
The methodology is applied to different cooperative wineries. In this paper we will show, as an example, the results from the Rochefort du Gard winery.
The proposed method starts off with a zoning study. It is then completed by an evaluation of potential quality of different kinds of soils and finally, it leads to practical application in order to enhance management of harvest selections in a quite precise professional context, which is that of cooperative wineries.

Variety and climatic effects on quality scores in the Western US winegrowing regions

Wine quality is strongly linked to climate. Quality scores are often driven by climate variation across different winegrowing regions and years, but also influenced by other aspects of terroir, including variety. While recent work has looked at the relationship between quality scores and climate across many European regions, less work has examined New World winegrowing regions. Here we used scores from three major rating systems (Wine Advocate, Wine Enthusiast and Wine Spectator) combined with daily climate and phenology data to understand what drives variation across wine quality scores in major regions of the Western US, including regions in California, Oregon and Washington. We examined effects of variety, region, and in what phenological period climate was most predictive of quality. As in other studies, we found climate, based mainly on growing degree day (GDD) models, was generally associated with quality—with higher GDD associated with higher scores—but variety and region also had strong effects. Effects of region were generally stronger than variety. Certain varieties received the highest scores in only some areas, while other varieties (e.g., Merlot) generally scored lower across regions. Across phenological stages, GDD during budbreak was often most strongly associated with quality. Our results support other studies that warmer periods generally drive high quality wines, but highlight how much region and variety drive variation in scores outside of climate.

Environment friendly nutrition supplying and soil cultivation methods applicable in the upper zone of hillside vineyards

Conservation: the best valorisation strategy for wine growing areas

Terroir encompasses many elements, including environment, grapes and human inputs that together contribute to the final wine quality of a certain wine growing area.

Insights into the stable isotope ratio variability of hybrid grape varieties

The wine industry faces the consumer’s increasing demand for a sustainable and environmentally-friendly production [1]. This demand has been shared and boosted by the European Union within the European Green Deal in the Farm to Fork strategy that aims to reduce a 50% the pesticide utilisation in farming systems. Among the agronomical approaches so far proposed, the use of mould resitant hybrid varieties -based on crossings of Vitis vinifera with other Vitis spp [2]- with a high tolerance to the attack of vine patogens is gaining the vinegrowers attention and the production area is continuously increasing

Effect of the presence of anthocyanins on the interaction between wine phenolic compounds and high molecular weight salivary proteins

As a result of climate change consequences, there is a gap between the times at which the grapes reach the phenolic and the technology maturities.
