«Observatoire Mourvèdre»: statistical modelling of quality for Cv. Mourvèdre

Abstract

Vine cultivar Mourvèdre is present all around the Mediterranean area and is interesting for its tannins and the specificity of its aromas. It is though difficult to manage. A wide project started in 1999 in order to determine what conditions are mostly important on the quality of the grapes and wines of Mourvèdre. During 5 years and on 32 different plots from Roussillon region up north towards Ardèche and east towards Var vineyards, a large amount of climatic, phenological, water stress, plant and grape data has been collected. Data mining PLS Spline method was used to model different variables of quality like sugar content in musts. The model obtained, that is able to predict the potential of a parcel, pointed out the major importance of the climate, as long as the yield and the leaf canopy management. It has then been validated on 4 different zones for the year 2005.

A NEW STRATEGY AND METHODOLOGY FOR THE CHARACTERIZATION OF POLYPHENOLS IN FINING PRECIPITATE

Polyphenols are secondary metabolite widely distributed in plant kingdom such as in fruits, in grapes and in wine. During the winemaking process, polyphenols are extract from the skin and seed of the berries. Fining is an important winemaking step just before bottling which has an impact on wine stabilization and clarification. Most the time, fining agent are animal or vegetal protein while some of them can be synthetic polymer like PVPP or natural origin like bentonite.
