An old cotton gin in Birmingham’s Avondale district is now the site of Cahaba Brewing Company’s new production facility and tasting room, which opened in January. Project architect Williams Blackstock Architects of Birmingham kept the brickwork intact, along with hand-made doors, an industrial elevator and other original details. New features harmonize with the old, including furniture made of reclaimed lumber from an old distillery in Kentucky. Cahaba is renting nearly half of a 51,000-square-foot building that is part of the Continental Gin Industrial Park.
