Basserman was owner of the Rock Brewery on State and Rock St. He blasted a cellar in at the foot of East Rock to start his brewery under which he excavated a cellar, 200 feet deep, 24 feet wide, and 16 feet high, for storing his brewings. The average production of this brewery was from 15,000 to 20,000 barrels a year. Once in business, he made a large bottling plant. The brewery proper comprised a three-story building, partly of stone, 185 by 50 feet in dimensions, while the attached sheds and barns covered an area 688 by 50 feet. It was also remembered for its authentic German beer gardens, built next to the brewery. Although the building was destroyed in a fire, part of the wall remains. Across the street he built a residence for his employees, which was later known as the "George Basserman Building".
George Basserman was married to Emily. They had a daughter named Anna who married William Hall August 2, 1914. The Hall family still owns several properties in the Cedar Hill community.
