1. Cuvasion: In 2009, Cuvaison opened their new Carneros tasting room next to their solar powered facility. Just a few short years after completing the solar power facility, Cuvasion is actually producing more energy that it needs. On top of that, they are also active in with the code of Sustainable Winegrowing Practice, sustainably farmed, certified Napa Green Winery & Green Land, and active in cork recycling. Pretty impressive. You can even check out their website that maintains an accurate report of the output of their solar energy.
