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.

Monferace a new “old style” for Grignolino wine, an autochthonous Italian variety: unity in diversity

Monferace project is born from an idea of 12 winegrowers willing to create a new “old style” Grignolino wine and inspired byancient winemaking techniques of this variety (1). Monferace wine is produced with 100% Grignolino grapes after 40 months of ageing, of which 24 in wooden barrels of different volumes. Grignolino is an autochthonous Italian variety cultivated in Piedmont (north-west Italy), recently indicated as a “nephew” of the famous Nebbiolo (2) and is used to produce three different DOC wines. The Monferace Grignolino is cultivated in the geographical area identified in the Aleramic Monferrato, defined by the Po and Tanaro rivers, in the heart of Piedmont and the produced wine is characterized by a high content of tannins, marked when young, that evolve over the years. Its color is generally slight ruby red and garnet red with orange highlights with ageing.

How do we describe wine imagery? Expertise shapes language usage and multimodal imagery for wine

The acquisition of wine expertise is a multi-faceted and multisensory process with implications for sensory perception, attention, memory, and language production. With the prevalence of the predictive model of brain functioning, one area of burgeoning research interest involves wine mental imagery, since the brain relies on imagined experiences to build predictions for the future. Recent evidence has shown that, for instance, those with higher imagery vividness are more susceptible to wine advertising. However, little is known about the association between mental imagery and other associated cognitive processes, such as the ability to produce words that describe such imagery. 

Exploring the mechanisms underpinning grapevine susceptibility to esca in a range of Vitis vinifera L. cultivars

Grapevine susceptibility to fungal diseases, including the vascular disease esca, is a major threat for wine productivity and vineyard perennity worldwide.

Non-linear unmixing as an innovative tool to detect vine diseases in UAVs, airborned and satellite images: preliminary results

Vine diseases have a strong impact on vineyards sustainability, which in turns leads to strong economic consequences. Among those diseases, Flavescence dorée spreads quickly and is incurable, which led in France to the setup of a mandatory pest control implying the systematic use of pesticides and the prospection and uprooting of every infected plants. Remote sensing could be a very powerful tool to optimize prospection as it allows to produce quickly accurate maps over large areas. Recent studies have shown that high spatial resolution (10cm/pixel) multispectral images acquired from UAVs allow to map Flavescence dorée in vineyards using leaves discolorations [e.g. Albetis et al., Remote Sensing, 2017].
