Vintage influence on Grenache N, Syrah N and Mourvedre N in Côtes du Rhône (France)

Abstract

Vintage is part of « terroir ». The aim of this work is to study, through vine and berry parameters, the effect of vintage on the three major red grape varieties in Côtes du Rhône : Grenache N, Syrah N and Mourvedre N. We first characterized vintages 1997 to 2003, highlighting similar features in grape development across the different cultivars since 2001 only. Then we showed that vintage becomes the major effect only if vine vigour is stabilized. Indeed, there is a strong relationship between an excess of vigour and berry size on Grenache and Mourvedre, whereas fertility of Syrah is reduced when vigour is decreased. This work has to be continued by integrating meteorological data, to explore more precisely the effect of vintage on vine and grape development.

Ten years soil diagnosis in vineyards, with particularly analysis of organic and microbial mass and measuring their evolution

Since 1996, we study the soil in viticulture, specially in the South of France. In the field, we delimit soil units and observe soil profiles and take samples to analyse its physical, mineral, organic and microbial mass composition

Settling precocity and growth kinetics of the primary leaf area: two indicative parameters of grapevine behaviour

Le comportement de la vigne en terme de fonctionnement thermique et hydrique, influe de manière directe sur la qualité des baies de raisin. L’effet du terroir peut être perçu à travers l’étude de paramètres tels que la précocité, la mise en place de la surface foliaire ou la vigueur. Une expérimentation a été conduite en Val de Loire sur le cépage chenin dans le but de mieux comprendre le rôle des variables liées au terroir sur la croissance et le développement de la vigne et in fine sur la qualité des baies.
