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.

FREE TERPENE RESPONSE OF ‘MOSCATO BIANCO’ VARIETY TO GRAPE COLD STORAGE

Temperature control is crucial in wine production, starting from grape harvest to the bottled wine storage. Climate change and global warming affect the timing of grape ripening, and harvesting is often done during hot summer days, influencing berry integrity, secondary metabolites potential, enzyme and oxidation phenomena, and even fermentation kinetics. To curb this phenomenon, pre-fermentative cold storage can help preserve the grapes and possibly increase the concentration of key secondary metabolites. In this study, the effect of grape pre-fermentative cold storage was assessed on the ‘Moscato bianco’ white grape cultivar, known for its varietal terpenes (65% of free terpenes represented by linalool and its derivatives) and widely used in Piedmont (Italy) to produce Asti DOCG wines.

Characterizing the effects of nitrogen on grapevines with different scion/rootstock combinations: agronomic, metabolomic and transcriptomic approaches

Most vineyards are grafted and include a variety (Vitis vinifera) grafted over a wild Vitis rootstock (hybrids of V. berlandieri, riparia and rupestris). Grape berry quality at harvest depends on a subtle balance between acidity and the concentrations of sugars, polyphenols and precursors of aroma compounds. The mechanisms controlling the balance of sugars/acids/polyphenols are influenced by the abiotic environment, in particular nitrogen supply, and interact with the genotypes of both the scion variety and the rootstock. Previous work suggests that some of the effects of water stress are in fact linked to a nitrogen deficiency driven indirectly by the reduction of water absorption.

Applications of FTIR microspectroscopy in oenology: shedding light on Saccharomyces cerevisiae cell wall composition and autolytic capacity

Many microbial starters for the alcoholic and malolactic fermentation processes are commercially available, indicated for diverse wine styles and quality goals. The screening protocols cover a wide range of oenologically relevant features, although some characteristics could also be studied using underexplored powerful techniques. In this study, we applied Fourier Transform Infrared (FTIR) microspectroscopy [1,2] to compare the cell wall biochemical composition and monitor the autolytic process in several wine strains of Saccharomyces cerevisiae.

Energy partitioning and functionality of photosystem II in water-stressed grapevines during heatwaves revealed by continuous measurements of chlorophyll fluorescence

The increased intensity and frequency of heatwaves, coupled with prolonged periods of drought, are a significant threat to viticulture worldwide. During these conditions the more exposed leaves can show visible symptoms of heat damage. We monitored the functionality of photosystem II (PSII) in the field to better understand the impact of heatwaves on canopy performance. A factorial experiment was established in summer 2023 using Shiraz grapevines in the Barossa valley of South Australia, involving water-stressed and well-watered vines.

Zonificación climática de las D.O. Rueda y Toro y vinos de la tierra de medina del campo

La producción vitícola es el resultado de una serie de factores influyentes (variedad, patron) dentro de un medio ecológico­-climatico-edafico, en el que se interactua por medio de técnicas de cultivo adecuadas.
