Abstract
As a case study, our research assessed the impacts of climate variations on grape composition of Chenin blanc in the Anjou-Saumur wine growing sub-region, France.
A long-term assessment was made on the influence and relation between climate trends and modifications in berry compounds and ripening speed.
From here, data were collected for flowering and veraison growing stages for various studied clones of Chenin blanc in the middle Loire Valley.
Study findings highlight the important trends in grape composition over time, providing an overview of climate change impacts on grape quality.
While model performances may still require improvements, this study also is the first step towards quantifying heat requirements of different clones and how they can provide adaptation solutions for winegrowers to sustain wine identity in a changing climate.
