(Wines&Vines) - Simple steps can save thousands of gallons of water in winery operations. Industry experts delivered the message during a seminar about water conservation organized by Napa County and held in Yountville on Thursday. Dr. Anita Oberholster, a University of California, Davis, cooperative extension specialist in enology, said wineries can conserve a great deal of water simply by reusing rinse water during cleaning or sanitizing tanks. “Your last rinse can be your first rinse,” she said.
