National Mustard Day

Observed annually since 1991 on the first Saturday in August, National Mustard Day honors the beloved condiment at the National Mustard Museum in Middleton, Wisconsin. The lively street festival closes downtown streets and draws thousands of mustard fans for mustard tastings, games like ring toss, live music, and more. The museum’s celebration highlights mustard’s centuries-old history while supporting a nonprofit museum that houses over 7000 mustards and mustard memorabilia.
