Flying Dog Brewery originally opened in 1990 as a brewpub, it became the first brewery to open in Aspen in over 100 years. The reputation of Flying Dog beers grew quickly, and demand soon exceeded the brewpub’s capacity. So, in 1994 Flying Dog opened bigger brewery in Denver, Colourado. By 2006 demand had grown worldwide, and Flying Dog purchased a second brewery located in Frederick, Maryland in May 2006, and in January 2008 all production was moved to this facility.
Flying Dog beer’s unique illustrations are created by Ralph Steadman, best known for his illustrations of the works of Hunter S. Thompson – to whom Gonzo Imperial Porter was created in honour of.
Flying Dog was named Best Mid-Sized Brewery at the 2009 Great American Beer Festval.
