Sierra Nevada Brewing Co.

Sierra Nevada is easily one of the greenest breweries that doesn't make all of their beers using organic ingredients. As MNN's own Robin Shreeves points out, the company does a lot to green up their environmental footprint including drawing energy from their own private solar panel farm, recycling nearly everything that comes into their office, like the New Belgium Brewery, they process their own wastewater on site to generate methane which they burn to create electricity. They do have one certified organic brew though, the Sierra Nevada Estate Homegrown Ale, which goes the extra step by being made with hops and barley grown on company grounds.
