Proposition of a simplified approach of the viticultural landscape

Abstract

Une approche très simple de la lecture des paysages est proposée sur la base de l’expérience acquise par l’observation de divers terroirs du monde.
La manière selon laquelle est construit un paysage tourne autour de 2 éléments fondamentaux, des facteurs naturels et des facteurs humains.
Le premier élément est la morphologie du lieu qui est due principalement à la disposition et à la nature des couches géologiques, qui déterminent directement et fondamentalement l’ossature, le squelette du paysage et donc ses grandes lignes.
Le deuxième élément est la sculpture fine des détails du paysage qui est strictement du domaine du travail de l’homme qui, soit par contrainte, soit par aspect pratique, accompagne ces grandes lignes définies par la nature.
L’observation attentive de très nombreux paysages conduit invariablement à classer tous les éléments d’un paysage parmi ces deux seuls ensembles.
Elle permet de montrer comment, à travers quelques exemples pris dans différents vignobles du monde, la tectonique et la disposition actuelle des couches géologiques, ainsi que leur nature déterminent les lignes principales des paysages viticoles.
Un premier classement des grands types de paysages viticoles est proposé selon ces critères.
Par ailleurs, sont abordées, à travers différents exemples, les limites entre le rôle des facteurs naturels et des facteurs humains, c’est-à-dire dans la lecture de chaque paysage quels sont les éléments constitutifs qui peuvent être classés dans chacune des deux catégories.

Application of cyclic voltammetry to the classification of enological tannins in relationship to oxygen consumption rate and botanical origin 

Enological tannins are a diversified group of winemaking products that vary in several aspects such as chemical composition, botanical origin, and production method. In consideration of their richness in phenolic compounds, one of their main application in vinification is related to their antioxidant capacity, in particular their ability to consume oxygen during red wine maturation.

Agronomic and oenological characterization of the intraspecific cross ‘Passau’ in the aim of its commercial use

The study of new wine grape cultivars can be interesting to diversify the local wine productions without using international varieties. With this aim some Vitis vinifera intraspecific crosses obtained by Prof. Dalmasso in the 1930s and registered in the Italian National Catalogue in 1977, have been studied in the last years.

Creativini: an augmented reality card game to promote the learning of the reasoning process of a technical management route for making wine 

Nowadays, the entire viticultural and enological process is wisely thought out according to the style of wine to be produced and the local climatic conditions. Acquiring the approach of a technical management route specific for wine production remains a complex learning process for students. To enhance such learning, The Ecole d’Ingénieurs de PURPAN (PURPAN), an engineering school located in Toulouse southwest France, has recently developed Creativini, a collaborative card game in English made of 150 cards spread into 14 batches. Students in groups of 3 to 6 must design a technical production route, from plant material to bottling.

Une méthode d’étude synthétique du paysage

a) wine, a qualitative and user-friendly product, favors a visual support, even for a scientific study because it refers to the image of the terroir, in particular by its visible landscape. b) the vineyard landscape, which is fairly open by definition, favors this type of approach. c) the framework of the Terroir Test conducted by the URVV (INRA – Angers) comprises 15 micro-plots of 100 strains, and requires at this scale precise surveys of the environment, hence systematic shots, of the center of the plot, over 360°, at 50 mm intervals, at 1.70 m from the ground and horizontally.

Are dicysteinyl polysulfanes responsible for post-bottling release of hydrogen sulfide?

Hydrogen sulfide (H2S) has a significant impact on wine aroma attributes and wine quality when present at concentrations above its aroma threshold of 1.1 to 1.6 μg/L.
