They are especially popular in areas of the US where German-Americans settled in large numbers, like Sheboygan, Wisconsin, which is informally known as the "Bratwurst Capital of the World" because of the city and county's very strong German roots and connections to bratwurst. Johnsonville Foods, the nation's largest bratwurst maker, is based in the nearby unincorporated village of Johnsonville. The city also celebrates Sheboygan Bratwurst Days, a community festival held on the first Thursday-Saturday of August each year that celebrates the bratwurst. Other traditional Wisconsin brat manufacturers include Klement's Sausage Company and Usinger's, both of which are based in Milwaukee.
