The Lagunitas Brewing Company is a brewery founded in 1993 in Lagunitas, California and moved a year later to nearby Petaluma, when they quickly outgrew their original rural West Marin location.
The brewery is known for iconoclastic interpretations of traditional beer styles, and irreverent descriptive text and stories on its packaging. The company is the fifth top selling craft brewery in the US, as of 2014.
You can take a tour of the brewery with your dog as well, but four legs are only allowed on the first floor.
