Sur la réalité du lien entre le terroir et le produit : de l’analyse sémantique à l’approche écologique

Abstract

Les réflexions présentées ici sont une synthèse d’un ensemble de recherches sur la construction d’une logique scientifique concernant les relations entre le terroir, la vigne, le vin, et sur l’étude d’un produit, le vin, considéré comme la résultante de nombreuses interactions entre facteurs d’ordres variés. Ce travail a beaucoup bénéficié de discussions d’ordre épistémologique autant que de nature technique avec l’ensemble des chercheurs de l’U.R.V.V. (Angers) et avec nos collègues de l’Institut National des Appellations d’Origine, pendant plusieurs années. La réalité du lien entre un terroir et un produit est complexe ; elle l’est tout particulièrement dans le cas du vin. Sa vérification et l’analyse des phénomènes en termes de causalité nécessitent l’approche détaillée du produit intermédiaire – le raisin – et des itinéraires techniques correspondants, tant à la vigne qu’au chai : itinéraire technique de conduite de la parcelle et de l’exploitation viticole, jusqu’à la vendange ; itinéraire technique de conduite des opérations de vinification.

Il nous est apparu, peu à peu, la nécessité incontournable de repréciser le sens des mots utilisés dans toutes nos démarches : le respect du sens des mots conduit à une plus grande rigueur dans les idées qu’ils véhiculent et, partant, à une meilleure garantie de la validité des raisonnements qu’ils permettent de formuler et d’échanger. L’analyse sémantique ainsi conduite s’est révélée un outil de travail extrêmement cohérent dont la résultante constitue la base d’un programme logique de recherches expérimentales. Le respect du sens des mots est une garantie du respect des idées qu’ils représentent et, en même temps, une garantie contre d’éventuelles erreurs de logique scientifique.

Malbec wines from Argentina: influence of climate on aromatic components and Organoleptic profile. Is it possible to stablish regional identities?

Malbec grapes have been cultivated for 150 years in Argentina. In the last 20 years Argentinian Malbec wines have emerged as a commercial boom worldwide.

An efficient protocol for long-term maintenance of embryogenic calluses of Vitis vinifera

New breeding techniques (NBTS) could play a significant role in the genetic improvement of grapevine by producing new grape varieties with improved quantitative and qualitative characteristics. However, the application of these new techniques faces some technical challenges. One of the challenges is the generation of embryogenic calluses, which are not only difficult to obtain but it is also difficult to maintain their competence during in vitro cultivation, and thus regenerate plants without defects.

Sparkling wines and atypical aging: investigating the risk of refermentation

Sparkling wine (SW) production entails a two-steps process where grape must undergoes a primary fermentation to produce a base wine (BW) which is then refermented to become a SW. This process allows for the development of a new physicochemical profile characterized by the presence of foam and a different organoleptic profile.

Effect of vigour and number of clusters on eonological parameters and metabolic profile of Cabernet Sauvignon red wines

Vegetative growth and yield are reported to affect grape and wine quality. They can be controlled through different techniques linked to vine management. The objective of this research was to determine the effect of vine vigour and number of clusters per vine on physicochemical composition and phenolic profile of red wines. The experiment was carried out during two vegetative cycles, with cv. Cabernet Sauvignon grafted onto Paulsen 1103. Three vine vigour were defined, according to shoot weight at previous harvests, being low, medium and high. Five treatments of number of clusters were used for each vigour, with 15, 22, 29, 36, and 45 clusters per vine. Grapes from all treatments were harvested in the same day from Brix and total acidity criteria. Thirty days after bottling, classical analyzes and phenolic compounds were performed. As results, different responses were obtained from each vintage. In 2020, a dry season from veraison to harvest, grapes and wines obtained from low vigour treatment and 45 clusters per vine was the highest in sugar and alcohol content respectively, while grapes and wines from high vigour and 15 clusters presented the lowest sugar and alcohol content. Total anthocyanins were higher in treatment with low vigour and 15 clusters, while the lowest amounts were found in low vigour with 45 clusters, as well as medium and high vigour with 36 clusters per vine. Total tannins were higher in high vigour with 22 clusters and medium vigour with 29 clusters, while were lower in low vigour with 36 clusters. In 2021, a wet season at harvest, responses were different, and great variations were observed between treatments. As conclusions, yield and vine vigour had strong influence on grape and wine quality, promoting different enological potentials on which can be indicated/used for aging strategies of red and even rosé wines.
