Consider this one glass of white wine is equivalent to 29 gallons of water. And one glass of red wine is 32 gallons of water.
If you look at the entire wine region area in the U S wine grapes sipped a little over 1 trillion gallons of water from wells and rivers in one year alone.
Climate change is going to increase the need for irrigation. We're already beginning to see that as summers become longer and hotter, and the winters become colder. One study found worldwide viticulture acreage will not be suitable for wine production by 2050.
In California, where most of our grape-growing occurs in the United States. It's predicted wine grapes will decrease between 50-63% by 2050.
The good news is there are ways to farm wine grapes that use less water and are more climate resilient. I learned this when I spent the day with Mike Benzinger, who was my tour guide and the founder of Benzinger family wines.
