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.

The role of malolactic bacteria metabolism on the organoleptic qualities of wines

Lactic acid bacteria (LAB) are essential microorganisms in winemaking due to their role in malolactic fermentation (MLF) [1]. This process not only ensures the biological stabilization of wine through the decarboxylation of malic acid into lactic acid but also contributes to modifications in the chemical composition of the wine [2][3].

Post-plant nematicide timing for northern root-knot nematode in Washington wine grapes

Vigor declines in older vineyards and poor vine establishment in replant situations have been attributed to plant-parasitic nematodes. The northern root-knot nematode, Meloidogyne hapla, is the most prevalent plant-parasitic nematode species found in Washington wine grape vineyards. Management for nematodes in established vineyards is limited to the application of post-plant nematicides. We are evaluating new nematicides that are currently not registered in grape for their efficacy in controlling M. hapla and a part of that evaluation includes improving the alignment of nematicide application timing with the vulnerable second-stage juvenile (J2) life stage of M. hapla.

Development of a new indicator of grape skin ripening in relation to Botrytis cinerea susceptibility

The bunch rot induced by Botrytis cinerea is an important disease of grapevine that causes a diminution of grape quality and a considerable yield loss leading to an economic loss

Maturation of Agiorgitiko (Vitis vinifera) red wine on its wine lees: Impact on its phenolic composition

Maturation of wine on lees (often referred as sur lie) is a common practice applied by many winemakers around the world. In the past this method was applied mainly on white and/or sparkling wine production but recently also to red wine production. In our experiment, we matured red wine on wine lees of two origins: a) Light wine lees, collected after the completion of the alcoholic fermentation, b) Heavy lees, collected after the completion of the malolactic fermentation. The lees were free of off-odors and were added in the red wine in percentage 3% and 8%, simulating common winemaking addition. The maturation lasted in total six months and samples were collected for analysis after one, three and six months. During storage the lees were stirred.

Modelling grape and wine quality through PLS Spline statistical method

Started in 1994, this project intends to explain quality of grapes and wines using data of soil, climate and vineyard that are currently used in field trials.
