BHA, propyl gallate, citric acid to help protect flavor. Johnsonville Chorizo Sausage: Our company began in 1945 when Ralph F. and Alice Stayer opened a small butcher shop in Johnsonville, Wisconsin. Their philosophy was simple; make great-tasting meats and treat people well. Today, Johnsonville remains an independent, family-owned company. Every member of our team takes great pride in sharing our founder's standard for quality and doing right by others.
