Abstract
The probable evolution of the climate, grows rich by a historical wine glance. The vine could illuminate this major challenges linked to climate change in particular thanks to the historical analysis of “ban des vendanges” de (grape harvest data) as well as the physiological and phenologic observations in the various wine-producing areas, the last and future evolution of the climate. The wine historians and experts studied the variability of the round of applause of vintage during the last five centuries. The precocity observed since the end of 1980 is from 10 to 20 days comparatively in the middle of the 20th century. In complement the recent historical data make it possible to apprehend in a simple way the influence of the climate change on the dates of grape harvest (10 days average precocity per additional degree Celsius). An European LIFE project ADVICLIM (www.adviclim.eu), coordinated by CNRS aims to set up a network of international measurements and a Web platform which will make it possible to the wine growers to evaluate the impacts of the climate change on their pieces. The objective of the communication is to present the historical aspects of the dates of grape harvest in link with the variations of the climate and to determine the future trends to be planned to adapt to the various scenarios during the 21st century.
