Potentiel des sols viticoles et qualité des vins

Abstract

[English version below]

La qualité des vins dépend de différents facteurs et procédés, notamment de la nature des terrains viticoles. Dans ce travail, nous avons cherché à établir les liens entre descripteurs pédologiques des parcelles et descripteurs sensoriels des vins. Sur la base de Classifications Ascendantes Hiérarchiques (CAH) et d’Analyses en Composante Principale (ACP), il a été possible d’établir des liens entre la nature des parcelles (sableuse, argileuse, sablo-graveuleuse) et certains descripteurs sensoriels des vins (chaleur, astringence, fruit noir) et plus globalement avec le type de vins élaborés.

Wine quality depends on various factors and processes, including type of soil. In this study, we sought to establish links between pedological data and sensory attributes of wines. Based on Hierarchical Ascendant Classification (HAC) and Principal Component Analysis (PCA), it was possible to establish links between the nature of the parcels (sandy, clayey, gravelly-sand) and some wine sensory descriptors (heat, astringency, black fruit) and more generally with the type of wines.

A new step toward the comprehensive valorisation of grape marc through subcritical water extraction of polysaccharides

Évolution de la surmaturation du cépage Chenin dans différents terroirs des Coteaux du Layon en relation avec les variables agroviticoles

The French “Coteaux du Layon” Appellation of Origin has built its Jarne on the production of sweet white wines. A network of experimental plots, based on the “terroir” concept, was established in 1990; it allows for the follow-up of the overripening behaviour of the grapes in relation with the agroviticultural parameters.
