Key phenolic compounds in the pulp of new red-fleshed table grape hybrids: anthocyanins and flavonols 

Il n’existe presque pas d’études qui caractérisent l’effet du climat viticole sur la typicité des vins en considérant les différents types de climats à l’échelle mondiale. Cette étude fait partie d’un projet CYTED de zonage vitivinicole. L’objectif a été de caractériser l’effet du climat viticole sur la typicité des vins sur une macro région viticole du monde.

The local wine as an area identified and recognized is a complex socio-historical reality that calls an effort of observation and theoretical reflection using various social sciences

Aim: Northwest China occupies an important position in China’s wine regions due to its superior geographical conditions with dry climate and sufficient sunlight. In this work, we aimed to investigate the physico-chemical colour and flavour characteristics of red wine in Northwest China.

The terroir is today the most important factor of production and development in the wine sector. In a context where the commercial challenge is taking place all over the place, the distinction between traditional and “new” producing countries is not only a geographical, cultural and technical counter position but also, and above all, a legal one. Indeed, the system of standards present in the “old world” (plantation rights, production decrees, yields per hectare, etc.) which may represent, in the short term on the global market, constraints to development and product innovation must become an opportunity. But threats become opportunities, if we work, from the vine to the market, via communication, more on the elements of difference than on those of affinity.

es indices agroclimatiques concernant le bilan hydrique et la température moyenne de l’air, ont été utilisés pour la caractérisation des zones avec différentes aptitudes pour la viticulture de vin (Vitis vinifera L.) dans l’état du Maranhão, Brésil.
