It was promoted by Billy Carter, whose older brother Jimmy was then the president of the United States. In October 1978, Falls City announced that it was closing after less than a year of Carter's promotion. The beer was produced by Cold Spring Brewing, West End Brewing, and Pearl Brewing Company. In 2018 Uptown Brewing Company and Billy Beer, Inc. entered into a partnership with Greene County, North Carolina to build a 10,000 sq. foot production facility at the North West Greene Industrial Park.
