Founded as the Boulder Brewing Company in 1979 as the first craft brewery in Colorado; it started brewing the following year. In 1990, the company changed its name to Boulder Beer Company. In 1993 the company again renamed itself as the Rockies Brewing Company. In 2005, the company again changed its name back to the Boulder Beer Company.
In January 2020 the brewpub closed but through a new partnership with Sleeping Giant Brewing Company in Denver, who will continue to brew, package and distribute the Boulder Beer brands to the retail market, the brand will stay alive.
