Establishment of a geodatabase ‘for the characterization of the viticultural “terroirs” of “canton de Vaud” (Switzerland)

Abstract

[English version below]

La caractérisation objective des terroirs viticoles est nécessaire pour mieux comprendre les relations existantes entre les sols, la plante et la qualité de la production vinicole. Dans le cadre d’une recherche sur les terroirs viticoles du canton de Vaud – Suisse, un géorépertoire pédologique et agronomique a été conçu et réalisé. Son objectif est d’offrir une structure d’accueil et de traitement des données pédologiques et agronomiques récoltées sur le terrain. C’est un outil de saisie et d’exploitation, qui facilite la caractérisation des sols viticoles et la mise en valeur des données agronomiques. Couplé à un système d’information géographique, il permet d’en faire la synthèse et l’interprétation. Toutes les données relatives aux vignobles sont ainsi centralisées. La base de données réalisée fonctionne sur les logiciels couplés Access et Maplnfo. Ce couplage de la base- avec un système d’information géographique (SIG) permet de confronter les données pédologiques et agronomiques à celles du microclimat et d’en déduire finalement les unités terroirs recherchées.

The objective characterization of the viticultural “terroirs” is necessary in order to better understand the relationships between soils, plants and wine production quality. As part of a research on the viticultural “terroirs” of “canton de Vaud” – Switzerland, a pedological and agronomical geodatabase was designed and realized. Its purpose is to offer a structure that can store and treat the pedological and agronomical data collected in the field. This tool allows to capture and analyse information in order to facilitate the characterization of viticultural soils and the exploitation of agronomical data. All the vineyard data can be summarized and interpreted with one database, coupled with a Geographic Information System (GIS). The realized database works with Access and Mapinfo connected together. The coupling of the database with a geographic information system allows to put together pedological, agronomical and microclimatic data and analyse them to deduce “terroirs” unities.

Wine aging : a bottleneck Story ?

The sporadic oxidation of white wines remains an open question, making wine shelf life a subjective debate. Through a multidisciplinary synoptic approach performed as a remarkable case study on aged bottles of white wine, this work unraveled a yet unexplored route for uncontrolled oxidation.

Evolution of the metabolic profile of grapes in a context of climate change

In the current context of global climate change, anticipating the evolution of the oenological potential of emblematic grape varieties of regions such as Burgundy and Champagne is a guarantee of the sustainability of a sector which has considerable economic weight. however, if various models of climate change cast doubt on the sustainability of these grape varieties in these regions, appellation decrees, as well as consumer expectations, do not allow or consider the use of alternative grape varieties. In addition, control/compensation methods such as irrigation are also not permitted.
