High Noon Watermelon Hard Seltzer is the property of E & J Gallo Winery in Modesto, California, which has been in operation since its founding in 1933 by Ernest and Julio Gallo. Though they are the largest exporter of California wines (not to mention the largest family-owned winery in the country), they have also become an incubator for some of the most successful new non-grape products on the market — High Noon Watermelon Hard Seltzer being a prime example.
