The Lagunitas Brewing Company is a brewery founded in 1993 in Petaluma, California, USA. They are known for iconoclastic interpretations of traditional beer styles, and irreverent descriptive text and stories on their packaging. Lagunitas Brewing's flagship, IPA, is consistently the best-selling IPA in the state of California according to IRI, the widely cited consumer product reporting company.
The brewery was founded in 1993 by Tony Magee in Lagunitas, California and moved to nearby Petaluma when they quickly outgrew their original rural West Marin location. Over the years from 1993 through 2007, Lagunitas has been among the fastest growing craft breweries in the U.S. producing nearly 52,000 barrels in 2007.
