CALIFORNIA PEACHES

California produces 84% of the country's fresh peaches as per a report from the Unesco Institute for water education. Agriculture uses 80% of California's water supply. 8 ounces of peaches need 37.5 gallons of water. 
3.48 gallons of water needed to produce one ounce of wine. California crushed nearly 4 million tons of wine grapes in 2014. The state leads the nation in wine grape production. You do the math.
