The Heurich Brewery was located in Foggy Bottom at the present site of the Kennedy Center. The massive brick structure was four stories tall and had 40-foot underground vaults, where an immense system of vats and tanks transformed water and hops into beer. Like the Heurich mansion in Dupont Circle, the brewery was designed to look like a German castle, complete with a crenelated tower and mock arrow slits. Heurich had so much confidence in the fireproof design that he didn't have a dollar of insurance on the building.

Christian Heurich was a brainy autodidact who made a point of keeping up with the latest technological advances. According to the Evening Star, this included annual trips back to Europe to "study the improved methods in use in the large breweries of the old country." Heurich pioneered several techniques such as pasteurizing his product to extend the its shelf life. He was also the first person to market his beer with special themed packaging during the holidays, which is now a standard practice.

Heurich's brewery offered 13 differient beers with names like Capitol and Old Georgetown. In 1900 his Senate and Maerzen beers won the silver medal at the Exposition Universelle in Paris, where they were recognized for their clarity and purity. In 1905 they won the gold medal at the Exposition Universelle et Internationale de Leige, Belgium.
