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.

Effects of different soil types and soil management on greenhouse gas emissions 

Soil is important in the carbon cycle and the dynamics of greenhouse gases (CO2, CH4 and N2O). Key soil characteristics, such as organic matter content, texture, structure, pH and microbial activity, play a determining role in GHG emissions[1]. The objective of the study is to delimit different types of soil, with different soil management and to be able to verify the differences in CO2, CH4 and N2O emissions. The study was carried out in a vineyard of Bodegas Campo Viejo in Logroño (La Rioja), whose plant material is Vitis vinifera L. cv. Tempranillo.

Effect of alcoholic strength on the phenolic and furfural compounds of Brandy de Jerez aged in Sherry Casks®

Brandy is a spirit drink produced from wine spirit aged for at least six months in oak casks with a capacity of less than 1000 L and minimum alcohol by volume (ABV) of 36%. During the aging process, physicochemical and sensory changes take place. Manifested by colour, flavour or aroma variations that improve the quality of the initial distillate.

Factors involved in the acumulation of acetic acid inside the grapes during winemaking by carbonic maceration

Vinification by carbonic maceration (CM) is based in the anaerobic fermentative metabolism also called intracellular fermentation (IF).

Evaluation of consumer behaviour, acceptance and willingness to return of faulty wines

The analysis of consumer attitudes towards wine, especially towards wines perceived as faulty, is an aspect that requires more research than has been carried out so far [1]. This study aims to analyse consumer behaviour in situations involving the consumption of faulty wines and to assess the level of acceptance of such wines.

AGING PATTERNS OF VARIETAL VOLATILE PROFILES OF WHITE WINES: A CASE STUDY ON 18 ITALIAN VARIETAL WHITE WINES

During wine aging many compositional changes take place. In particular, aroma undergoes dramatic modifications through a wide range of reactions that to date are only partly understood. Italy owns one of the largest ampelographic heritages worldwide, with over three-hundred different varieties. Among these, many white grapes are employed for the production of dry still white wines. Some of these wines are consumed young while others are more prone to aging. For many of these wines, the aging patterns related to volatile composition are still unknown.
