Climate change is expected to make many grape-growing regions too hot and dry to produce high-quality wine from traditional varieties. But scientists at the University of California, Davis, have found that wine grape varieties from regions that are more prone to stress have traits that could help them cope with climate change.
The study, published in the Journal of Experimental Botany, finds that varieties that produce their best wines in warmer, drier regions have traits that conserve water, helping the vines extend their water resources to last over the growing season.
“The relationships between grape varieties and regions have historically been based on wine, without considering traits that affect drought or heat tolerance,” said lead author Megan Bartlett, an assistant professor in the Department of Viticulture and Enology. “These findings show these varieties could be more resilient to climate change than expected.”
