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.

INCREASING PINOT NOIR COLOUR DENSITY THROUGH SEQUENTIAL INOCULATION OF FLOCCULENT COMMERCIAL WINE YEAST SPECIES

Vitis vinifera L. cv. Pinot noir can be challenging to manage in the winery as its thin skins require careful handling to ensure sufficient extraction of wine colour to promote colour stability during ageing.1 Literature has shown that fermentation with flocculent yeasts can increase red wine colour density.2 As consumers prefer greater colour density in red wines,3 the development of tools to increase colour density would be useful for the wine industry. This research explored the impact of interspecies sequential inoculation and co-flocculation of commercial yeast on Pinot noir wine colour.

Characterization of vineyard sites for quality wine production using meteorological, soil chemical and physical data

The quality of grapevines measured by yield and must density in the northern part of Europe -conditions can be characterized as a type of “cool climate” – vary strongly from year to year and from one production site to another, i.e. différences in must densities can range from 30 to 50 °Oe. An explanation may be changes of weather conditions during critical developmental stages of the grapevines (2, 3, 5). These can be categorized as “macro climatic” influences.
