Where the World Gathers to Celebrate Every Day

NATIONAL MUSTARD DAY – First Saturday in August

National Mustard Day First Saturday in August


National Mustard Day on the first Saturday in August recognizes the versatile condiment. Used in a variety of cuisine, mustard comes from the seeds of a mustard plant (white or yellow mustard, Sinapis hirta; brown or Indian mustard, Brassica juncea; or black mustard, B. nigra).

The whole, ground, cracked, or bruised mustard seeds are mixed with water, salt, lemon juice, or other liquids and sometimes other flavorings and spices to create a paste or sauce. The color ranges from bright yellow to dark brown. Commonly paired with meats and cheeses, mustard adds zing to sandwiches, salads, hamburgers, and hot dogs.

Mustard also spices up many dressings, glazes, sauces, soups, and marinades. As a cream or a seed, mustard is used in the cuisine of India, the Mediterranean, northern and southeastern Europe, Asia, the Americas, and Africa. As a result, cooks reach for the spice and condiment more often than almost any other in the world. 

National Mustard Day is celebrated annually at the National Mustard Museum on the first Saturday in August. This fun-filled day for the whole family traditionally includes free hot dogs as well as music, games, other entertainment, free mustard sampling, and more. The Mustard Museum has been the official sponsor of this event since 1991.

In 2010, the event was moved to the current home of the Museum in Downtown Middleton, Wisconsin. With more than 6,000 enthusiastic mustard lovers in attendance annually, this event has raised thousands of dollars for local charity.
