Much of the water used in the brewing process doesn’t go into the beer itself. It’s used to cool the hot wort and clean the brewing tanks. At Block 15 in Corvails, Oregon, they catch and store excess water and reuse it in the cooling process on the next brewing day. They also use a closed-loop system to clean their tanks – treating the water and using it again. It takes a lot of water to produce a glass of beer, but from rainwater beer to other water reclamation efforts, breweries are doing a lot to reduce their water footprints.
