Antociani ed acidi cinnamici per la caratterizzazione di vitigni in zone diverse della Toscana

Abstract

The phenolic compounds (cathechins, cynnamic acids, anthocyanidins) in wines made from 6 vine-varieties (Sangiovese, Cabernet S., Nero d’Avola, Foglia Tonda, Pinot N., Mazzese) grown in 4 different pedoclimatic zones of Tuscany (Arezzo, Grosseto, Pisa and Lucca) have been analyzed by HPLC. The analytical datas were statisticaly worked out by Anova, Ancova, principal components analysis ACP and linear factorial discriminant analysis. A significati­ve differentiation in the phenolic composition of 6 vine-varieties have been found, so that an analytical key of separation has been found too. But also the 4 zones gave useful indication on the different behaviour of same vine-varieties (Sangiovese, Foglia Tonda, Nero d’Avola) in the different zones, so a positive interaction between the vine-variety and the environment was supposed. The other vine-varieties didn’t show phenolic composition significatively different in the 4 zones.

Barbera d’Asti: the characterization of the vineyard sites

[English version below]

L’objectif de l’étude est de mettre en évidence les différences rencontrées entre les vins Barbera d’Asti, qui sont produits en AOC. Celles-ci sont imputées aux terroirs caractérisés selon les facteurs pédologiques, climatiques, et qui conduisent à des différents potentiels viticoles et œnologiques. Il est proposé une individualisation des sous-zones.

Regional discrimination of shiraz using targeted and non-targeted analytical approaches

Aims: Shiraz is the most widely cultivated grape variety in Australia, and is grown under a range of viticultural and climatic conditions. Given its importance to the Australian wine sector, a number of studies have been conducted in recent years which involved a comprehensive assessment of grape composition, in order to objectively predict wine quality and style outcomes.

“Garrigues”, part of the mediterranean vine terroirs

Les paysages viticoles méditerranéens présentent une originalité qui ne se retrouve nulle part ailleurs : ils associent des garrigues très odoriférantes à des parcelles de vignes souvent qualitatives. La connaissance empirique des vins du Languedoc par leurs dégustateurs a conduit la Chambre d’Agriculture de l’Hérault à supposer que les arômes de la garrigue environnante peuvent se retrouver dans les vins (arômes de ciste, de genévrier, … )
