Sustainability Tour* California
BreweryDuration: 90 minutes | Ages 12+

The weather’s too nice in the summer; we can’t stay inside! Our sustainability tour covers much of the sunny brewery grounds, showcasing our alternative energy efforts and many of the initiatives based on our “reduce, reuse, recycle, rot” philosophy. You’ll check out California’s largest privately owned solar installation (10,500+ panels!), our fuel cell technology and the remarkable HotRot composter, as well as the recycling and conservation program that helped us divert 99.8 percent of our solid waste from landfills in 2012. Your tour will wrap up in our beautiful eight-acre hop field and lush two-acre garden where you can nosh on freshly harvested produce and enjoy educational tastings of our award-winning brews.
