Outils de caracterisation et zonage des paysages viticoles: application aux vignobles français

Abstract

[English version below]

Un paysage viticole est une relation entre des formes, dimension objective, et la perception que nous en avons, dimension subjective, émotionnelle. La viticulture n’est pas seulement productrice d’un vin, elle contribue également à façonner le paysage. Pourtant, jusqu’à présent, la connaissance des terroirs était principalement basée sur la caractérisation de leur aptitude à produire des vins de qualité.
Une méthodologie d’étude globale du paysage a été validée sur un site pilote champenois durant l’été 2003. Elle associait les acteurs du monde viticole et des collectivités territoriales au développement de la démarche paysagère locale. Elle liait l’étude sensible du paysage à la prise en compte du volet environnemental associé au terroir (ruissellement, érosion, biodiversité…).
L’élaboration de telles méthodologies nécessite la formalisation d’outil de caractérisation et de zonage des paysages viticoles.
Les principales données permettant de caractériser un paysage (cartographie, photos aériennes, données satellites, relevés de terrains bloc diagramme, données économiques …) sont décrites et présentées à partir de cas concrets.
Les principaux outils paysagers d’analyse et de communication, tels les sorties terrains ou un Système d’Information Géographique ont été étudiés.
Au final, l’objectif est de réaliser une « boîte à outils » permettant à différents niveaux d’échelle (national, régional, local) d’alimenter les démarches paysagères et environnementales, associées aux territoires viticoles.

Vineyard landscapes are a relationship between shapes which are objective and the perception that one has of them, which is subjective and emotional. Without this relationship, landscapes cannot exist. Vine farming does not only produce wine, it also contributes to design landscapes. Yet, so far, geographical specificities were essentially based on the characterisation of their ability to produce quality wine.
A comprehensive landscape study methodology was validated on a champagne pilot-site in summer 2003. It associated a sensitive landscape study to the environmental issues (runoff, erosion, biodiversity) and involved vine farmers and the district laborating such a methodology requires to formalise characterisation and zoning tools for vineyards landscapes.
The main landscape characterisation data are described and presented through case studies (cartography, air photographs, satellite data, site measures, economical data).
The main analysis and communication landscape tools, such as geographic information systems and onsite visits were studies. Finally, the aim is to create a tool box allowing vineyard landscape and environmental management on a local, regional and national scale.

OENOLOGICAL STRATEGIES FOR THE REMOVAL OF PINKING IN WHITE WINE

The pinking of in white wine is the turning of color from yellow to salmon hue. White wines obtained from certain grape varieties (e.g. Chardonnay, Sauvignon blanc, Riesling, Trebbiano di Lugana) showed to be susceptible to pinking [1] that has been evaluated by an assay providing the addition of hydrogen peroxide. Even if its appearance does not seem to affect the sensory properties [2], strategies are necessary for its removal. Nowadays, the treatment with polyvinylpolipirroline (PVPP) was reported to significantly decrease the pink color [3].

Influence of weather and climatic conditions on the viticultural production in Croatia

The research includes an analysis of the impact of weather conditions on phenological development of the vine and grape quality, through monitoring of four experimental cultivars (Chardonnay, Graševina, Merlot and Plavac mali) over two production years. In each experimental vineyard, which were evenly distributed throughout the regions of Slavonia and The Croatian Danube, Croatian Uplands,

Non-invasive quantification of phenol content during red wine fermentations

Phenolic compounds are responsible for the most important red wine quality attributes. Anthocyanins and tannins play crucial roles in color and mouthfeel properties of red wines. Phenolic analysis in the winery is hindered by analytical constrains.

Crown procyanidin quantification in red wines, rosé wines and Port wines

Condensed grape tannins play a major role in the organoleptic properties and quality of red wine. Recently, a new sub-family of macrocyclic condensed tannins has been identified in red wine and named “crown tannins”. Indeed, the first compound of the family identified and characterised by NMR was the crown procyanidin tetramer which is composed of a macrocyclic structure composed of four (-)-epicatechins link together by B-type interflavanoid linkage in the following an alternative sequences of C4-C8 and C4-C6 linkage. The 3D structure of this unusual crown procyanidin family reveals a central cavity in the molecule [1].

PROFILING OF LIPIDS IN WINES FROM MONOCULTURE FERMENTATION WITH INDIGENOUS METSCHNIKOWIA YEAST SPECIES

Lipids are a diverse group of organic compounds essential for living systems. They are vital compounds for yeast which makes them an important modulator of yeast metabolism in alcoholic fermentation. This study presents a comprehensive lipidome analysis of wine samples from the Vitis vinifera L., Maraština. The fermentation trails were set up in monoculture with different indigenous yeast strains selected from a collection of native yeasts established at the Institute for Adriatic Crops and Karst Reclamation in 2021, previously isolated from Croatian Maraština grapes: Metschnikowia pulcherrima, Metshnikowia sinensis/shanxiensis , and Metschnikowia chyrsoperlae.
