Denninger's originated in the Black Forest region of Germany where Rudolf Denninger and his wife Frieda operated three food stores. Shortly after immigrating to Canada in 1953, the Denninger family established their first store on King Street in Hamilton, Ontario the following year. Denninger's quickly developed reputation for producing high quality, European style sausages, as well as fresh and smoked meats. To meet increasing demand, new stores were added throughout the 1970s and 1980s and Denninger's became an integral part of shopping in Burlington, Oakville and Stoney Creek. Most recently they have opened their flagship store in Burlington.
