Billing itself as “the world’s first and only museum dedicated to the wonder that is vinegar,” the International Vinegar Museum first opened its doors in 1999 as a way to bring tourism to the tiny town of Roslyn, South Dakota. Located in the town’s former auditorium, built in the 1930s and listed on the National Register of Historic Places, the museum is the work of local vinegar enthusiast Lawrence “The Vinegar Man” Diggs.
Visitors can see and taste different vinegars from around the world, learn how vinegar is made and its many uses, and even see paper and ceramic made out of vinegar. Additionally, the museum hosts a Vinegar Festival every year, with a parade, tastings, cooking demonstrations, and a contest to crown the Vinegar Queen and “Royal Quart”.
