Natural variability and vine-growers behaviour

Abstract

[English version below]

Le vigneron est confronté à une variabilité naturelle omniprésente, liée au millésime et aux facteurs pédoclimatiques. Depuis 10 ans, en Champagne, la relation qu’entretient le vigneron avec l’espace a évolué. Les exemples d’entreprises collectives à vocation territoriale se sont multipliés : gestion de l’hydraulique viticole, maillages de groupements de conseil viticole (Magister), sites en confusion sexuelle, réseau maturation, analyses de sols par secteur, … Parallèlement, au niveau technique, des travaux de caractérisation du milieu naturel ont été initiés début 1990 en Champagne. Un réseau de stations climatiques a été mis en place, des cartographies de sols ont été dressées, et un réseau de parcelles expérimentales long terme est en cours d’implantation, pour mettre en relation les données du milieu naturel avec les caractéristiques des raisins et du vin. Des cartes conseil à 1/25 000 ont été établies : aléas de glissements de terrain, d’érosion, carte d’adaptation des porte-greffes ou d’aptitude à l’enherbement.

Par le biais du suivi de vignerons sur des sites pilotes, et des autodiagnostics de l’exploitation, réalisés dans le cadre de la viticulture raisonnée, on peut considérer les travaux de cartographie comme de réels supports de discussion et de progrès dans le choix des itinéraires culturaux. Reste désormais à valoriser les bases de données caractérisant le milieu naturel et les observations viticoles pour optimiser le choix de sites d’études représentatifs, extrapoler les résultats obtenus auprès des viticulteurs, et affiner une aide à la décision régionalisée.

In relation with natural environment, the vine-grower faces omnipresent natural variability, linked with year and pedoclimatic conditions. Since 10 years, in Champagne, the relation of the winegrower facing space has changed. Examples of collective actions with territorial purpose have increased: viticultural hydraulic management, network of advice viticultural groups, sectors with mating disruption, soil analysis by areas. Concurrently, at a technical level, studies on characterization of the natural factors began in 1990 in the Champagne vineyard: a network of weather stations was installed, soils were mapped, and longtime experimental network of plots is established, to study the relation between natural factors, vine and wine.

Based on these data, advice maps at the scale of 1/25 000 were established. It results from the following up of vine-growers that they consider cartographic studies as real tools to discuss and to make their vine-growing practices progress. The valorization of the data base, coming from the characterization of natural factors and viticultural observations remains, to better choice where to put experimental plots, and to help the vine-growers in their local choices.

Plant biostimulants in combination treatments as environmentally-friendly rest-breaking agents for dormancy release in table grapes Vitis vinifera Crimson Seedless

Context and purpose of the study. Vitis vinifera grapevine is a perennial crop which is globally cultivated, surviving cold winters in temperate zones by entering a state of dormancy.

Are Farm to fork strategy goals reasonable and achievable? State of the art of Península de Setubal’s winegrowers

The European Union’s “farm to fork” strategy sets out several objectives to be achieved by farmers, who, among others, relate to increasing biodiversity, protecting soils and reducing the use of pesticides. At a time when the amendments to the national plans of Sustainable Use of pesticides are being discussed, it is important to understand what the Setúbal Peninsula region status is.

Long-lasting flavour perception of wines treated with oenological additives considering the individual PROP taste-phenotype

The use of oenological additives is becoming a common practice due to the technological and sensory properties they provide to the wines. However, the number of studies focused on the impact that these additives might induce on wine flavor perception during wine tasting is still quite scarce. The aim of this work was to evaluate the effect of three different types of common oenological additives: two oenotannins (ellagitannin and gallotannin) and a commercial preparation of yeast mannoproteins on the long-lasting flavor perception (aroma and astringency).
