Swiss terroirs studies

Abstract

A multidisciplinary approach aiming at studying the grape-growing areas also referred as “Terroir” was initiated a few years ago in Switzerland. Collaborative studies are carried out on soil characteristics (I. Letessier, Bureau SIGALES; S. Burgos, Ecole d’Ingénieurs de Changins), climatic parameters (Swiss Federal Institute of Technology, Lausanne) and aspects of the plant physiology (Agroscope Changins-Wädenswil). The study of the soil includes the collection of geological and pedological characteristics and viticulturalist’s practical knowledge. It emerged that a large diversity in type and composition of soils was found and highlighted the importance of the parameter of soil water holding capacity (SWHC). In order to evaluate the climatic component of the “Terroir”, a model was built resulting in a climatic index taking into account temperature, radiation and wind protection. Agronomical studies revealed a good correlation between the physiology of the plant (water status, vegetative growth, sugar accumulation in berries) and the water content present in the soil (SWHC). Current studies aim at determining the influences of pedo-climatic factors on the quality of the final product in wine-growing areas in Switzerland.

Contribution of soil and atmospheric conditions to leaf water potential in grapevines

Etant lié au sol et aux conditions atmosphériques, le statut hydrique influence la physiologie de la vigne d’une part, mais joue aussi un role important en ce qui concerne la qualité du raisin et donc du vin d’autre part. Nous avons mesuré, dans la région de Stellenbosch, le statut hydrique sur des pieds de Sauvignon Blanc non irrigués, implantés sur 2 terroirs différents, l’un froid, l’autre plus chaud.
