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.

REDUCING NITROGEN FERTILIZATION ALTERS PHENOLIC PROFILES OF VITIS VINIFERA L. CV. CABERNET GERNISCHT WINE OF YANTAI, CHINA

Nitrogen (N) fertilizer is important for grape growth and the quality of wine. It is essential to address the mismatch between N application and wine composition. Cabernet Gernischt (Vitis vinifera L.), as one of the main wine-grape cultivars in China, was introduced to Yantai wine region in 1892. This grape cultivar is traditionally used for quality dry red wine with fruit, spices aroma, ruby red and full-bodied wines. In order to regulate vine growth and improve grape and wine quality, Cabernet Gernischt grapevines were subjected to decreased levels of N treatments, compared to normal N supply treatment, during grape growing seasons of 2019 and 2020.

CHARACTERIZATION AND IDENTIFICATION OF YEAST BIOACTIVE PEPTIDES RELEASED DURING FERMENTATION AND AUTOLYSIS IN MODEL WINE

Aging wine on lees is a consolidated practice during which some yeast components (e.g., polysaccharides,
proteins, peptides) are released and solubilized in wine thus, affecting its stability and quality.
Apart from the widely studied mannoproteins, the role of other yeast components in modulating wine
characteristics is still scarce. Wine peptides have been studied for their contribution to taste, antioxidant,
and antihypertensive potentials. However, the peptides detected in wine can be influenced by the
interaction between yeasts and grape components.

Measurement of synthetic solutions imitating alcoholic fermentation by dielectric spectroscopy

Having the possibility to use a wide spectrum of elecromagnetic waves, dielectric spectroscopy is a technique commonly used for electrical characterization of dielectrics or that of materials with high energy storage capacity, just to name a few. Based on the electrical excitation of dipoles (polymer chains or molecules) or ions in relation to the characteristics of a weak external electric field, this method allows the measurement of the complex permittivity or impedance of polarizable materials, each component having a characteristic dipole moment.In recent years, the food industry has also benefited from the potential offered by this technique, whether for the evaluation of fruit quality or during the pasteurization of apple juice [1-3]. As the tests are fast and do not destroy the products, dielectric spectroscopy proved to be an experimental tool suitable for online measurements as well as long-term monitoring.
