Vine, Wine and Climate Change

Grapevine is being affected by climate change in many ways, from earlier plant development - which could make vines more vulnerable to spring frosts - to earlier grape ripening.

Increasingly intense extreme weather events, such as heat waves and torrential rain, are also causing major damage to vines. Water stress, which is more pronounced in southern France, has a marked effect on yields. All French vineyards must contend with these issues. Wine characteristics are also changing, with higher alcohol levels, lower acidity and different aromas becoming more common. Meanwhile, new areas are becoming suitable for winegrowing.

The key to addressing these issues is to adapt faster. But how exactly should we do this? What decisions at the local or national level should be taken?

After ten years of research into adapting the French vine and wine industry to climate change, the LACCAVE project, led by INRAE, came to an end in 2021. This book summarizes the results of that project and explores possible levers for action, including new grape varieties; improved soif, water and training system management; reorganization of winegrowing areas; oenological innovations; and new regulations. Readers will find a systemic and strategic vision showing how these actions can be implemented through participatory approaches at different levels, from winegrowers to the winegrowing sector's own climate policy.

This reference book is aimed primarily at industry profes-sionals, lecturers and students.

The French version of this book received the 2024 01V Award from the International Organisation of Vine and Wine for the Sustainable Viticulture category.
