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 increasing frequency of extreme weather events (EWE) represents a severe threat to viticulture.

Lactiplantibacillus plantarum – A versatile tool for biological deacidification

Malolactic fermentation (MLF) is a secondary wine fermentation conducted by lactic acid bacteria (LAB). This fermentation is important in winemaking as it deacidifies the wine, converting L-malic acid into L-lactic acid and carbon dioxide, and it contributes to microbial stability. Wine pH is highly selective, and at pH below 3.5 generally only strains of O. oeni can survive and express malolactic activity, while under more favorable growth conditions above pH 3.5, species of Lactobacillus and Pediococcus may conduct the MLF. Among the LAB species Lactiplantibacillus plantarum strains have shown most interesting results under hot climate conditions, not only for their capacity to induce MLF, but also for their homo-fermentative properties towards hexose sugars, which makes them suitable for induction of MLF in high pH and high alcohol wines, when inoculated at the beginning of alcoholic fermentation.

Ageing of Sauvignon Blanc white wines with Specific Inactivated Dry Yeasts: Effect on physical and chemical characteristics

Del Barrio-Galán, R.a, b, Gómez-Parrini, A.a, Peña-Neira, A.b a Lallemand Inc. Chile y Compañía Limitada, Rosario Norte 407, piso 6, Las condes, Santiago, Chile b Department of Agro-Industry and Enology, Faculty of Agronomical Sciences, University of Chile, Post Office Box 1004, Santa Rosa 11315, La Pintana, Santiago, Chile It is well known that polysaccharides, mainly mannoproteins, play an important role on physical, chemical and sensory quality of wines. The ageing of white wines on lees is used in order to release higher amounts of polysaccharides by the autolytic processes in order to obtain higher-quality wines. However, this technique is too slow, because the temperature and pH conditions are not the most suitable for this process. In addition, it can also involve certain disadvantages such as a greater demand on winery resources, a longer period of wine storage, the appearance of reduction notes and some microbiological alterations.
