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.

Impact of yeast derivatives to increase the phenolic maturity and aroma intensity of wine

Using viticultural and enological techniques to increase aromatics in white wine is a prized yet challenging technique for commercial wine producers. Equally difficult are challenges encountered in hastening phenolic maturity and thereby increasing color intensity in red wines. The ability to alter organoleptic and visual properties of wines plays a decisive role in vintages in which grapes are not able to reach full maturity, which is seen increasingly more often as a result of climate change. A new, yeast-based product on the viticultural market may give the opportunity to increase sensory properties of finished wines. Manufacturer packaging claims these yeast derivatives intensify wine aromas of white grape varieties, as well as improve phenolic ripeness of red varieties, but the effects of this application have been little researched until now. The current study applied the yeast derivative, according to the manufacture’s instructions, to the leaves of both neutral and aromatic white wine varieties, as well as on structured red wine varieties. Chemical parameters and volatile aromatics were analyzed in grape musts and finished wines, and all wines were subjected to sensory analysis by a tasting panel. Collective results of all analyses showed that the application of the yeast derivative in the vineyard showed no effect across all varieties examined, and did not intensify white wine aromatics, nor improve phenolic ripeness and color intensity in red wine.

Caratterizzazione vitivinicola delle “Terre del Piacenziano” ricomprese nella zona D.O.C. “colli piacentini” attraverso l’analisi sensoriale dei vini prodotti

I territori della Riserva Geologica del Piacenziano sono parte del pedeappennino piacentino e sono noti per essere la culla del Pliocene, quel periodo di storia della Terra compreso tra 5.3 e 1.8 milioni di anni fa. Gli strati argillosi e sabbiosi riccamente fossiliferi qui presenti sono da sempre oggetto di studi geo-paleontologici tant’è che il Pliocene medio (3.6-2.6 milioni di anni fa) è internazionalmente noto come Piacenziano. Le analisi sensoriali strutturate dei vini qui prodotti hanno evidenziato, soprattutto per il vino Monterosso, le positive peculiarità dei loro caratteri sensoriali e descritto gli scostamenti significativi del loro profilo sensoriale rispetto agli altri vini presi a riferimento.
