Wine-growing regions around the world have recently been confronted with intense and frequent droughts and heat waves. Against this backdrop of climate change, scientists from the University of Bordeaux and INRAE have studied the drought resistance of grapevine vascular systems. They found that vulnerability varies widely between grape varieties, and identified the wine-growing regions most at risk. The results are published in the journal Scientific Reports.
