«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.

FLOW CYTOMETRY, A POWERFUL AND SUSTAINABLE METHOD WITH MULTIPLE APPLICATIONS IN ENOLOGY

Flow cytometry (FCM) is a powerful technique allowing the detection, characterization and quantification of microbial populations in different fields of application (medical environment, food industry, enology, etc.). Depending on the fluorescent markers and specific probes used, FCM provides information on the physiological state of the cell and allows the quantification of a microorganism of interest within a mixed population. For 15 years, the enological sector has shown growing interest in this technique, which is now used to determine the populations present (of interest or spoilage) and the physiological state of microorganisms at the different stages of winemaking.

Influence of berry maturity, maceration time and wine maturation on the polyphenols and sensory characteristics of pinot noir and Cabernet-Sauvignon

AIM: Combined investigation of the influence of berry maturity, maceration time and wine maturation on the changes in polyphenols and sensory characteristics of Pinot noir and Cabernet-Sauvignon.

What happens with the glutathione during winemaking and the storage of the wine?

We tried to give a part of the answer to this question by monitoring glutathione during winemaking and storage. The novelty of our approach is to quantify simultaneously the three known forms of glutathione: free glutathione (GSH), oxidized form (GSSG) and glutathione-S-sulfonate (GSSO3H).

The challenge of improving oenological quality in favorable conditions for productivity

Marselan (Cabernet-Sauvignon x Grenache), has been planted for more than 20 years now in Uruguay. Due to its good agronomic and oenological aptitudes under uruguayan conditions, it is currently the red variety with highest plantation rate. The objective of the study was to identify management practices, aimed at improving quality in highly productive vineyards, different fruit/leaf regulation methods were tested in southern Uruguay.
