Territoire, terroir et marché du vin à la production

Abstract

Les travaux visant à comprendre les relations entre un terroir, au sens agronomique, et les caractéristiques physico-chimiques des raisins ou du vin sont aujourd’hui nombreux, comme en témoigne le programme de ce colloque. Mais pour un économiste, la question centrale reste de savoir comment le terroir peut intervenir dans la construction de la valeur économique du vin et dans la différenciation de ses prix. L’effet terroir est-il reconnu par le consommateur final ou n’est-il qu’une variable d’ajustement interne aux systèmes de production ? A travers quels indicateurs cet effet terroir peut-il être géré par les différents opérateurs de la filière ? En définitive ne vaut-il pas mieux invoquer un “effet territoire” que peuvent construire les acteurs, et dont le terroir serait une des composantes possibles ? Pour développer ces questions, nous reviendrons d’abord sur les mécanismes de création de la valeur dans la filière viti-vinicole, pour proposer un cadre d’analyse permettant de relier les transactions au territoire et à sa composante terroir. Plutôt que de reprendre l’exemple des vins AOC, pour lesquels le terroir est largement mis en avant dans la construction de la qualité, nous avons préféré confronter notre analyse théorique au marché des Vins de table et de Pays à la production. En effet, dans ce marché se construit également une différenciation liée au territoire en parallèle ou en complément à une différenciation liée aux cépages. Deux approches différentes de ce marché seront présentés : une analyse statistique sur les contrats d’achat ONIVINS ; une série d’enquêtes auprès des opérateurs de la filière en Languedoc Roussillon.

Legacy of land-cover changes on soil erosion and microbiology in Burgundian vineyards

Soils in vineyards are recognized as complex agrosystems whose characteristics reflect complex interactions between natural factors (lithology, climate, slope, biodiversity) and human activities. To date, most of the unknown lies in an incomplete understanding of soil ecosystems, and specifically in the microbial biodiversity even though soil microbiota is involved in many key functions, such as nutrient cycling and carbon sequestration. Soil biological properties are indicative of soil quality. Therefore, understanding how soil communities are related to soil ecosystem functioning is becoming an essential issue for soil strategy conservation. Here, we propose to assess the importance of land-cover history on the present-day microbiological and physico-chemical properties. The studied area was selected in the Burgundian vineyards (Pernand-Vergelesses, Burgundy, France) where land occupation has been reconstructed over the last 40 years. Soil samples were collected in five areas reflecting various land cover history (forest, vineyards, shifting from forest to vineyards). For each area, physico-chemical parameters (pH, C, N, P, grain size) were measured and DNA was extracted to characterize the abundance and diversity of microbial communities. The obtained results show significant differences in the five areas suggesting that present-day microbial molecular biomass and bacterial taxonomic is partly inherited from past land occupation. Over longer period of time, such study of land-uses legacies may help to better assess ecosystem recovery and the impact of management practices for a better soil quality and vineyards sustainability.

Chenin Blanc Old Vine character: evaluating a typicality concept by data mining experts’ reviews and producers’ tasting notes

Concepts such as typicality are difficult to demonstrate using the limited set of samples that can be subjected to sensory evaluation. This is due both to the complexity of the concept and to the limitations of traditional sensory evaluation (number of samples per session, panel fatigue, the need for multiple sessions and methods, etc.). On the other hand, there is a large amount of data already available, accumulated through many years of consistent evaluation. These data are held in repositories (such as Platter’s Wine Guide in the case of South Africa Wine, wineonaplatter.com) and in technical notes provided by the producers.

Characterization of winegrape berries’ composition on sorting tables using hyperspectral imaging and AI

Comprehensive evaluation of grape composition at winery receiving areas often requires multiple measurements to ensure representativeness, as well as the use of analytical techniques that are time-consuming and involve sample preparation.

Microwave-assisted maceration and stems addition in Bonarda grapes: effects on wine chemical composition and sensory properties over two vintages

AIM: Bonarda, the second red grape variety in Argentina, produces high yields per hectare generating, in several cases, wines with low levels of quality compounds.

Conversion to mechanical management in vineyards maintains fruit

Current environmental, ecological and economic issues require a better vineyard production management. In fact, a poor use of fertilizing could lead to harmful impact on environment. Another issue concerns the cultures themselves which couldn’t use fertilizers efficiently, leading to a loss of income or too much expense for farmers. Presently, estimation of fertilization’s needs is realized by the laboratory analysis of leaves selected through a random sampling. The present study aims at optimizing fertilization’s management by using a map of biophysical parameters estimated from satellite images.
