In 1948, Aztec was purchased by the Altes Brewing Company of Detroit. Altes had originally been the Tivoli Brewing Company, but was renamed after its most popular beer. Edward P. Baker remained at Altes as a director of the new company. For whatever reason, Altes did not continue brewing the popular ABC Beer. Altes focused on its brands Altes, Altes “Brisk,” Altes Golden Lager and 7-11. Instead, the Famous ABC Beer brand was purchased by the Maier Brewing Company of Los Angeles and brewed there until at least 1957.
