Exposing wine grapes to sunlight was the key to making a good quality cabernet. But even the toughest grapes may not withstand the extreme heat that comes with climate change. Too much heat, like California has experienced with recent heat waves, can lead to jarringly jam-like wines that are high in alcohol and sugar and lacking in acidity.
Researchers at the University of California, Davis, have spent the last six years trying to find ways to solve this problem by examining different types of grapevine trellises and water amounts. A new study finds that switching away from one of the most common and widely used trellis systems could alleviate the effects of extreme temperatures on cabernet and other grapes. The study was published in the journal Frontiers in Plant Science.
