Anchor Brewing First Brews Liberty Ale

On April 18, 1975, Anchor Brewing in San Francisco first brewed Liberty Ale to commemorate the 200th anniversary of Paul Revere's ride. Developed under Fritz Maytag, the beer used American-grown Cascade hops and was later described by the Smithsonian’s National Museum of American History as a forerunner of the American India pale ale. Its assertive bitterness and hop aroma stood apart from the lightly hopped beers then dominant in the United States. Liberty Ale also helped establish two features that became central to modern American pale ale and IPA: the distinctive citrus character of Cascade hops and the renewed use of dry-hopping. The original commemorative beer was not immediately established as a permanent brand; Anchor continued developing related recipes through successive versions of Our Special Ale before introducing the regular Liberty Ale in the early 1980s. Its first brewing in 1975 nevertheless became an important bridge between the emerging American craft-brewing movement and the later rise of hop-forward American beer.
