Beyond colors of rosé wines: impact of origin and winemaking technology on their color, polyphenol and thiol compositions

Les effets de l’état hydrique et de l’alimentation en azote sur le potentiel aromatique des raisins de Sauvignon blanc ont été mesurés sur des vignobles du Bordelais. Les déficits hydriques ont été caractérisés par le potentiel tige déterminé en milieu de journée ΨTmin)­. L’alimentation en azote a été étudiée à partir d’une zone carencée en azote. Une part de cette zone a été supplémentée avec de l’azote minéral.

It is widely known the impact that oxidation has on wine sensory degradation and eventually, in the shortening of its longevity.

The objective of this study is to assess the potential for integrating sustainability guidelines into Geographical Indications of wine, especially in the case of the Denomination of Origin Campos de Cima da Serra (CCS), Brazil.

The METAPIWI project advances viticulture research by examining microbial communities in PIWI (fungus-resistant) grapevines compared to traditional Vitis vinifera. It investigates how these microbes influence spontaneous fermentation and the production of distinct metabolites and aromas.

The viticulture of the Douro Delimited Region, one of the heirs of ancestral viticulture, traditionally empirical and of quality, while integrating modernity and contemporary tools, respects and has always present the principles on which it was developed.
