International Vinegar Museum, Vinegar museum in Roslyn, South Dakota.
The International Vinegar Museum in Roslyn, South Dakota, is a museum dedicated to a single product: vinegar. It brings together over 350 varieties from around the world, including unexpected flavors like pecan, tequila lime, maple, and blueberry.
The building opened in 1936 as the Roslyn Auditorium, built with funding from a federal employment program created during the Great Depression. It was listed on the National Register of Historic Places in 2001.
The annual Vinegar Festival in late June elects an honorary "royal quart" and a "vinegar queen" and features a parade, cooking workshops and tastings. The museum's name and the town's identity are tied to this event, which grew from the community's search for a feature unlike any other in the area.
The museum sits on Main Street in Roslyn and is open mainly during summer, through Labor Day. Opening hours are limited to certain days of the week, so it helps to check before you go.
The museum's shop sells its own line of vinegars, including flavored varieties, alongside a balsamic imported from Italy. The collection began with vinegar that Lawrence Diggs researched at San Francisco State University before moving to Roslyn in 1989.
