The influence of terroir on the quality of wine of the Cahors A.O.C

Abstract

[English version below]

Dans le but d’améliorer la qualité et la typicité des vins de l’Appellation d’0rigine Contrôlée CAHORS, une étude a été réalisée afin de mettre en évidence l’adéquation Cépage-Terroir- Qualité du vin. Selon la méthodologie proposée par MORLAT et ASSELIN (1992), neuf unités terroirs ont été déterminées. Sur chacune, des parcelles de référence homogènes quant au matériel végétal Cot ou Malbec ( cépage principal de cette appellation greffé sur S04, et aux méthodes culturales, ont été suivies au niveau agronomique et œnologique (GARCIA et al., 1996). Les résultats ont permis de déterminer les potentialités viticoles et œnologiques de chaque terroir. Des stratégies de gestion de vignoble peuvent être proposées aux vignerons afin de leur permettre la production de vin présentant les meilleurs qualités et typicité en fonction de leurs terroirs.

The aim of this study was to identify terroir-cultivar-wine quality adequations in order to improve the quality and typicity of wines from the “Appellation d’Origine Contrôlée” CAHORS. According to the approach defined by MORLAT and ASSELIN (1992), nine wine terroir units were characterized. Within each of these units, reference plots with homogeneous plant material (Cot or Malbec, the main cultivar, grafted on S04) were identified. These plots were also submitted to the same cultural practices and tillage operations. Furthermore, all the plots were subjected to the same agronomical and enological practices. Results were used to determine the viticultural and enological potentialities of each terroir. Relevant vineyard management strategies can thus be proposed to winegrowers in order to produce wines with the highest quality and typicity in relation to the vineyard terroir.

EFFECT OF MICRO-OXYGENATION IN COLOR OF WINES MADE WITH TOASTED VINE-SHOOTS

The use of toasted vine-shoots (SEGs) as an enological tool is a new practice that seeks to improve wines, differentiating them and encouraging sustainable wine production. The micro-oxygenation (MOX) technique is normally combined with alternative oak products with the aim to simulate the oxygen transmission rate that takes place during the traditional barrel aging. Such new use for SEGs implies a reduction in color due to the absorption by the wood of the responsible compounds, therefore, given the known effect that MOX has shown to have on the modification of wine color, its use together with the SEGs could result in an interesting implementation with the aim to obtain final wines with more stable color over time.

Influence of climate change conditions (elevated CO2 and temperature) on the grape composition of five tempranillo (Vitis vinifera L.) Somatic variants

The current levels of greenhouse gas emissions are expecting to provoke a change on the environmental conditions which, among others, will include a rise of global mean surface temperature and an increment of atmospheric CO2 levels (IPCC, 2014), known as climate change. The response of grapevine (Vitis vinifera L.), one of the most important crops in Europe, from both a cultural and economic point of view, is not completely understood yet and the studies considering the interaction between factors are scarce. Besides, the potential variety of responses among somatic variants needs to be studied in order to be exploited in the avoidance of undesired traits linked to climate change (Carbonell‐Bejerano et al., 2015).

Sustainable viticulture’ the “semi‐minimal” pruned “hedge” system for grape vines long term experience on cv. Sangiovese (Vitis vinifera L.)

In previous experiments carried out in Bologna on Sangiovese grapevines raised with the Australian “Minimal Pruning” system, it has been shown that this system left an excessive burden of buds on the vine.

Parcours de découverte des terroirs viticoles

A partir des recherches conduites sur la caractérisation des terroirs viticoles par des chercheurs de l’Unité de Recherches Vigne et Vin (1, 2, 3, 4, 5) du Centre INRA d’Angers, Terre des Sciences, le Centre de Culture Scientifique et Technique d’Angers (CCSTA) a mis au point un parcours de découverte d’une journée dans le vignoble angevin avec une approche pluridisciplinaire.
