Study of the sensory dimension of the wine typicality related to a terroir and crossing with their viticultural and oenological characteristics

Abstract

The typicality of a product can be characterized by properties of similarity in relation to a type, but also by the properties of distinction. The typicality related to the soil is associated with a delimited geographical origin, and with asserted characteristics. The aim of this study is to determine the sensory profile of typical wines and to interrelate with their technical characteristics. A quantitative descriptive analysis was carried out by an expert panel on 34 wines from Vintage 2005 (23 “Anjou-Villages Brissac” and 11 “outsiders”). All these wines came from plots being able to product the A.O.C. “Anjou-Villages Brissac”. In addition, a characterization of the typicality of the products was carried out with “just about right” profiles, by a group of professionals of this area, from descriptors raised by discussion with all the producers of the area. Finally, a crossing of the sensory data with viticultural and enological practices was carried out.
The results showed the relevance of the expert panel in the discrimination of the products. Two groups could be distinguished, one consisted essentially of wines “Anjou-Villages Brissac” and the other consisted essentially of wines “outsiders”. The panel of professionals proved to be relevant on the characterization of the total quality of the wines, but did not appear consensual for more precise descriptors. The crossing of sensory profiles with some technical acts showed significant effects of “thinning out of leaves”, “disbudding”, “maceration” and “fermentation with industrial yeast” on sensory characteristics.

Prospects of thermal imaging as a non-invasive tool to assess water status for irrigation scheduling in commercial vineyards

Aim: Irrigated viticulture is expanding worldwide mainly as a short-term adaptation strategy to climate change. Plant-based methods are increasingly being used for irrigation scheduling in commercial vineyards. Canopy temperature (TC) has long been recognized as an indicator of plant water status. TC, but also the thermal stress indices, e.g. crop water stress index (CWSI) and stomatal

THE EFFECT OF COPPER ON THE PRODUCTION OF VARIETAL THIOLS DURING THE ALCOHOLIC FERMENTATION OF COLOMBARD AND GROS MANSENG GRAPE JUICES

Nowadays, the rapid growth of vineyards with organic practices and the use of copper as the only fun-gicide against downy mildew raises again the question of the effect of copper on varietal thiols in wine, especially 3-sulfanylhexan-1-ol (3SH) and its acetate (3SHA). A few decades ago, several works indicated that the use of copper in the vineyard had a negative effect on the content of varietal thiols in Sauvignon blanc wines [1, 2]. However, these studies only considered the concentration of the reduced form (RSH) of varietal thiols, without quantifying the oxidised ones. For this purpose, we proposed to monitor both reduced and oxidised forms of varietal thiols in wine under copper stress during alcoholic fermentation to have a more complete picture of the biological and chemical mechanisms.
