Old Vienna is a brand of beer bottled by City Brewing, and later, Koch Beverage Company, in the 19th century in Wapakoneta, Ohio. City Brewing was owned by Karl Kolter and his son Charles, who immigrated from Wallhalben, Germany, to Ohio in the mid-19th century. The business was later handed down to Henry Koch, Charles's son-in-law. By the early 20th century the brewery had closed down.
It is now a Canadian produced beer. Old Vienna was brewed by Carling O'Keefe who acquired the rights and recipe after Koch Beverage Company's demise, and through the 1970s and 1980s it was the mainstream lager brand sold by the brewery. It is now produced by Molson Breweries where it is still being sold in Canada and in select markets in border U.S. states. Old Vienna is currently produced in bottles, cans and on draft with a 5% alc./vol. content. For a time in the 1970s and 1980s OV was available in 7 oz. bottles called "OV Splits".
