The key role of vineyard parcel in modifying flavor compounds of Cabernet Sauvignon grapes

Young white wines should be consumed within a short time after bottling to avoid loss of their fresh, fruity attributes. Shelf-life of white wines can be extended if they are stored under suitable conditions of time and temperature prior to consumption.

The Institut Français De La Vigne Et Du Vin (IFV) is conducting many experiments on innovative winegrowing practices, which are emerging in companies in the sector, or which are still at the R&D stage for agricultural suppliers. The purpose of these practices may be to reduce environmental impact, to adapt vineyards to climate change, or to achieve other technical, economic or social aims. Whatever the objective, it is necessary to verify the relevance of these new practices, and in particular their environmental relevance, i.e. That at the very least, the changes in practices do not increase the environmental impact of the technical itineraries.

Kokumi is a complex sensation perceived as enhanced palatability.

This work gives a summary of the most important programmes about viticultural « terroirs », developed on the « Côtes du Rhône » controlled appellation area for about twenty years.

La société et l’état imposent plus que jamais à la viticulture française de prendre en compte ses impacts environnementaux tout en produisant des vins de qualité. Après avoir présenté ces impacts, les auteurs exposent la méthode de l’Analyse du Cycle de Vie. Ils proposent une démarche pour sa mise au point pour évaluer les impacts environnementaux en viticulture AOP en Val de Loire dans le cadre de l’évaluation de la compatibilité des objectifs qualitatifs et environnementaux de la production de raisins de cuve.
