Blame it on the Red Sox.
After the Boston Red Sox lost the World Series, Barry Levenson wandered into an all-night supermarket. It was October 28, 1986. In the mustard aisle came the thought: “If you collect us, they will come.” A dozen jars became a collection, then a museum.
Levenson was an Assistant Attorney General for Wisconsin before he left the law for mustard. The museum opened in Mount Horeb in 1992, moved across the street in 2000, and came to downtown Middleton in 2009. The collection now brings together mustards from all 50 states and more than 70 countries, with antique tins, jars, advertisements and mustard pots.
“I argued a case before the Supreme Court with a jar of mustard in my left pocket. We won!”
