Improvement of the red wine AOC Grignolino d’Asti typicality using some technological innovations

Abstract

[English version below]

L’AOC Grignolino d’Asti (20000 hl environ de production) est un vin de la province de Asti, produit avec le raisin rouge du cépage de même nom originaire du Piémont (Nord-Ouest d’Italie). Ces derniers temps l’AOC a enregistré des pertes économiques considérables dues aux caractéristiques peu agréables des vins : couleur (nuances jaune-orangée), l’astringence et l’amertume plutôt évidentes. Le but de ce travail est la valorisation sernorielle du vin dans le respect de sa typicité. Nous avons étudié trois techniques récentes de vinification : la microoxygénation, l’utilisation de préparations enzymatiques, la macération à froid. Également, nous avons défini la typicité et évalué l’acceptabilité de vins du Grignolino d’Asti du commerce, des vins expérimentaux et de leurs témoins. Les résultats de la première année d’étude montrent que les techniques utilisées n’ont pas modifié la typicité du vin, mais n’ont pas apporté d’amélioration qualitative.

 

The AOC Grignolino d’Asti (about 20.000 hl produced) is a red wine of the Asti province; it is produced with the same red grape variety, which is native of Piedmont (North-West of Italy). In the last years it has been observed a drop in its sales, probably due to the unpleasant characteristics of its colour (yellow tones) and to its evident astringency and bitterness. The aim of this work is to improve the sensory characteristics of this wine respecting its typicality. We applied three rew winemaking techniques: the micro-oxygenation, the use of enzymes and the cold maceration. The typicality of this wine has been defined and aiso the acceptability of some commercial wines and of the experimental wines. The results of the first year of studies show that none of the winemaking techniques used improve the quality of this product.

Trans-resveratrol concentrations in wines Cabernet Sauvignon from Chile

This study evaluated the levels of trans-resveratrol in commercial wines made from Cabernet Sauvignon grapes from different valleys of Chile stilbenes. The Cabernet Sauvignon is the most planted variety in Chile, being 38% of the total vineyard country. Chile is the fourth largest wine exporter in the world, so it is important to evaluate the Cabernet-Sauvignon wines in their concentration levels of trans-resveratrol and its relation to the benefits provided to human health in moderate consumption. Evaluation comprises commercial wines from different valleys of Chile and its relationship with climatic characteristics, soil and vineyard handling.

An intra-block study of bunch zone air temperature and its impact on berry and wine attributes

Temperature is a key environmental factor affecting grape primary and secondary metabolites. Even if several mesoscale studies have already been conducted on temperature
especially within a Protected Designation of Origin area, few data are available at an intra-block scale. The present study aimed at i) assessing the variability in bunch zone air temperature within a single vineyard block and the temporal stability of temperature spatial patterns, ii) understanding temperature drivers and
iii) identifying the impact of temperature on grape berry attributes.

Effect of ageing with Specific Inactivated Dry Yeasts on the volatile composition of Sauvignon Blanc and Carménère wines

Chile y Compañía Limitada, Rosario Norte 407, piso 6, Las Condes, Santiago, Chile The wine is a complex matrix made up of several compounds which can interact among themselves throughout the wine ageing process, thereby modifying their sensorial characteristics. It is well known that during ageing of wines on lees, polysaccharides (mainly mannoproteins) can be released and can interact with the aromatic fraction modifying its volatility.
