Viticultural zoning applications at the detailed scale of a cooperative winery: terroirs in St­hilaire-d’Ozilhan (AOC Côtes-du-Rhône)

Abstract

[English version below]

La maîtrise de la typicité du vin s’élabore au niveau local ou communal d’une exploitation viticole et/ou d’une cave, unité de vinification. La cave coopérative de Saint-Hilaire­-d’Ozilhan (AOC Côtes-du-Rhône), dont le territoire communal s’étend sur une superficie de 1 670 ha, couvre près de 310 ha cultivés en vigne. Elle réalise des vinifications «au terroir», en utilisant des regroupements d’unités de sol en 9 unités de terroir potentiellement viticoles, définies en s’appuyant sur la parenté des substrats. Diverses sélections d’une même unité peuvent aboutir aussi à des vins différents, ce qui suggère une hétérogénéité spatiale de certaines unités définies. Une carte des terroirs issue d’une approche par l’analyse spatiale géomorpho-pédologique est par ailleurs disponible pour la cave coopérative, munie de son niveau plus détaillé, la carte des unités de pédopaysage. La comparaison des différentes cartes disponibles suggère diverses options applicables aux sélections de vendange. Par ailleurs, l’utilisation de fonctions de pédotransfert a permis d’estimer la réserve utile.

Wine quality needs to be monitored at the detailed local scale of the winery or viticultural farm territory. The territory covered by the cooperative winery of Saint-Hilaire-d’Ozilhan (AOC Côtes-du-Rhône), is a 1 670 hectares-commune area, nearly 310 hectares of which are grown into vine. This winery has been working for nearly a decade on geographical and enological mana gement. Wine-making processes are based on 9 “terroir” land divisions, defined with the substrata indicated in soil map units. Distinct selections of the same unit can lead to different wines, thus indicating the spatial heterogeneity of some of the units defined.
A zoning obtained from soil and landform spatial analysis, is available for this winery from another source, with a detailed soil landscape map. The comparison of the varied documents available may apply to different harvest selections.

Characterization of a strain of Lachancea thermotolerans, microorganism of choice when facing the climatic challenges of the wine sector

Current climatic challenges in the wine sector require innovative solutions to maintain the quality of wines while adapting oenological practices to changing conditions. This article presents the detailed study of a lachancea thermotolerans strain on matrices typical of the French mediterranean area.

Les motivations du vigneron en quête de l’expression “terroir”

During the 1985 harvest, I was able to notice in the taste perception a break in the harmony of the wine during even partial blends of grapes from different plots. At the same time, I noted a good reaction from customers for greater product customization. As a result, I was led to seek the objective limits of the terroir of a cuvée and by a constant and permanent refinement of the parameters specific to each of the terroirs.

Discrimination of monovarietal Italian red wines using derivative voltammetry

Identification of specific analytical fingerprints associated to grape variety, origin, or vintage is of great interest for wine producers, regulatory agencies, and consumers. However, assessing such varietal fingerprint is complex, time consuming, and requires expensive analytical techniques. Voltammetry is a fast, cheap, and user-friendly analytical tool that has been used to investigate and measure wine phenolics.

The origin and the discovery of “terroir”

Le mot “terroir” dérive du latin “terra”, mais déjà les Romains l’indiquaient comme “locus” ou”loci”, c’est-à-dire un lieu ayant le “genius”destiné à la production d’un produit d’excellente qualité.

Sviluppo vegetativo del Nebbiolo nell’area di produzione del Barolo DOCG: influenza sulla qualita’ della produzione

Environment features and management operations on shoot and leaves modify the canopy during the vegetative season, changing the grapevine microclimate and the ratio between photo synthetic sources (the canopy) and productive sinks (the grapes).
