Climate change impacts
Climate change is already having a variety of impacts on wine production. Effects include earlier grape harvests, increased water stress on grapes, increased alcohol content, and reduction in acidity.

Adaptation activity
Between 2012 and 2015, the French National Institute for Agriculture (INRA) worked with 23 research institutes variously specializing in climatology, genetics, ecology, crop cultivation, wine brewing, economics, sociology, etc. in the LACCAVE ("Long-term Adaptation to Climate Change for Viticulture and Enology”) project, developing comprehensive studies such as the assessment and adaptation of grape and wine production. There were seven working groups in LACCAVE, which focused on: ①the organization of existing research on climate change and its impacts in wine orchards; ②basic physiological and genetic studies of grapes, and their reaction to climate change; ③technological innovations that contribute to adaptation; ④evaluation of different regional strategies; ⑤consideration of economic strategies; ⑥the creation of information systems that take into account the specificities of various scientific fields; and ⑦developing a proactive response to the adaptation of French vineyards.
Outputs / Expected benefits
Vineyards are taking adaptive measures, such as selecting late-harvesting and lower sugar-content grape varieties, using yeast to limit sugar fermentation, modifying cultivation methods based on climate change simulations, and changing regulations, based on the assessment of research data.
