Interest in measuring the grape texture to characterise grapes from different cultivation areas – Example of Cabernet franc from the Loire Valley

Abstract

A two-bite compression test was applied on Cabernet franc grapes during two harvest seasons. The evolution of the texture parameters from véraison to harvest was studied and a new mechanical ripeness notion was introduced. The ripeness stage and the parcel type effects on the texture properties were investigated, considering ten sampling dates and three parcels. A sensory description of the same grape samples was also performed. The compression test and the sensory evaluation allowed discrimination between ripeness levels and parcels types. The influence of the parcel type and the harvest season were highlighted. Indeed each parcel behaved differently from the others toward climatic conditions. High correlations were observed between some sensory descriptors and texture indices in 2005. This work confirmed the interest of the grape texture as an indicator of the grape ripeness in relation with the terroir.

Role of Harvesting Time/Optimal Ripeness in Zone/Terroir Expression

La maturité optimale est définie en fonction du style de vin désiré, qui est fonction du marché. Le sol et le climat ont un effet sur la typicité des vins. Le niveau qualitatif des raisins et des vins, et le potentiel pour obtenir différents styles de vin est déterminé par l’association des caractéristiques naturel du terroir et les technologies mises en

EVOLUTION OF CHEMICAL AND SENSORIAL PROFILE OF WINES ELABORATED WITH THEIR OWN TOASTED VINE-SHOOTS AND MICRO-OXYGENATION

The positive contribution of toasted vine-shoots (SEGs, Shoot from vines – Enological – Granule) used in winemaking to the chemical and sensory profile of wines has been widely proven. However, the combination of this new enological tool with other winemaking technologies, such as micro-oxygenation (MOX), has not been studied so far. It is known that micro-oxygenation is used in wineries to stabilizes color, improves structure or combining with oak alternatives products to achieve a more effective aroma integration of wines. For that, its implementation in combination with SEGs could result in differentiated wines.

Contribution à l’étude des relations entre des variables de fonctionnement des terroirs du Val de Loire et l’évolution des acides organiques des baies durant la maturation du raisin

Dans les terroirs du Val de Loire, la précocité du cycle de la vigne et son alimentation en eau sont des variables de fonctionnement qui influent de manière importante sur la composition des baies à maturité.

Analysis of primary, secondary and tertiary aromas in Vitis vinifera L. Syrah wines with an extemporaneous production cycle in two regions of São Paulo – Brazil, using GC-MS

The aromatic perception is one of the main factors that influence the
consumer when determining the wine’s quality and acceptance. Numerous factors (soil, climate,
winemaking style, cultivar) can influence the volatile compounds. Some of these compounds are released directly from the grape berries while others are formed during the fermentation and aging processes. However, little is known about the quality and aromatic formation of Syrah variety in the winter cycle cultivated in São Paulo.

Managing alcohol in sparkling wine production: adjusting harvest timing and utilizing grape juice in “liqueur de tirage”

Context and purpose of the study. Sparkling wine production is majorly impacted by climate change as sugar accumulation and aromatic development in grapes are often decoupled.
