MASHOUT is the Mid-Atlantic States Homebrewers CampOUT, a 4-day outdoor celebration of the homebrewing hobby held each summer. MASHOUT began in 1988 with the combined efforts of Washington, DC's BURP (Brewers United for Real Potables) and Frederick, MD's FOAM (Frederick Original Ale Makers) homebrew clubs. The first MASHOUT was held at the Hagan Farm (also known as the Mink Farm) in Thurmont, MD and attracted some 60 homebrewers. The event was so popular that it was repeated the next year at the same location.
