International audienceViticulture and wine production are facing climate change. While it can be a challenge in some regions, it is an opportunity for others. The aim of this study is to develop a methodology to assess climatic characteristics and potential for viticulture of new areas, through spatial analyses of data from temperature-based grapevine models (the Grapevine Flowering Veraison model-GFV and the Grapevine Sugar Ripeness model-GSR) during current and future periods. A deadline for veraison was set on the 1 st of September for dry wine and on the 15 th of September for sparkling wine.
