According to the 2018 harvest report from California Wines, California’s 2018 harvest “played out like a dream’ for winegrowers throughout the state. This is due to favorable moderate temperatures throughout the spring and summer and a long grow season. The United States Department of Agriculture forecast volumes of 4.1 million tons in August 2018, 2 percent growth from 2017 and above the average of 3.9 million tons.
