Even though the thought of happy farm animals munching on spent grains is a happy thought and makes bacon all the tastier, with the ever expanding craft beer universe more avenues for the spent grain need to be found.
And a California brewery is going down one of those avenues by using an anaerobic digestion system. Sounds kinda disgusting but it converts the grains into bio-gas which then can be used to power the brewery.
Devil’s Canyon in San Carlos has teamed with the Pure Energy Group to create a system that does just that. And the plan is to expand to other breweries in San Francisco in the future.
Maybe this tech will move down south to LA and become a viable option for breweries here.
