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.

Identification of a stable epi-allele associated with flower development and low bunch compactness in a somatic variant of Tempranillo Tinto

Grapevine cultivars are vegetatively propagated to preserve their varietal characteristics. However, spontaneous somatic variations that occur and are maintained during cycles of vegetative growth offer opportunities for the natural improvement of traditional grape cultivars. One advantageous trait for winegrowing is reduced bunch compactness, which decreases the susceptibility to pests and fungal diseases and favor an even berry ripening.

ANTHOCYANINS EXTRACTION FROM GRAPE POMACE USING EUTECTIC SOLVENTS

Grape pomace is one of the main by-products generated after pressing in winemaking.Emerging methods, such as ultrasound-assisted extraction with eutectic mixtures, have great potential due to their low toxicity, and high biodegradability. Choline chloride (ChCl) was used as a hydrogen bond acceptor and its corresponding hydrogen bond donor (malic acid, citric acid, and glycerol: urea). Components were heated at 80 °C and stirred until a clear liquid was obtained. Distilled water was added (30 % v/v). A solid-liquid ratio of 1 g pomace per 10 ml of eutectic solvent was used.
