Middleton, Wisconsin has a free mustard museum with its own fake college and 6,000 jars

It’s all Barry Levenson’s fault

You can walk into a museum in Middleton, Wisconsin, and taste your way through dozens of mustards without paying a dime.

The National Mustard Museum holds more than 6,000 jars from all 50 states and over 70 countries, and it sits right on Hubbard Avenue in the middle of downtown.

The whole place runs as a nonprofit, pulls in tens of thousands of visitors a year, and never charges admission. How it got started involves a baseball heartbreak and a late-night grocery run.

A sleepless night in a supermarket aisle

Barry Levenson worked as an assistant attorney general for the state of Wisconsin. In October 1986, his Boston Red Sox lost the World Series to the New York Mets, and he couldn’t sleep.

So he wandered into a 24-hour supermarket in the middle of the night and walked out with about a dozen jars of mustard. That kicked off the collection.

Levenson kept practicing law for years after that, even arguing a case before the U.S. Supreme Court. In 1991, he quit to go all in on mustard.

The museum moved twice before landing in Middleton

Levenson opened the museum to the public in Mount Horeb, Wisconsin, on April 5, 1992. Eight years later, he moved it across the street to a bigger space.

Then in November 2009, the whole operation relocated to Middleton and took the name National Mustard Museum. Middleton sits just outside Madison, about 10 minutes from the state capitol.

The building fills two floors, with exhibits downstairs and the gift shop up at street level.

Thousands of jars line the Great Wall of Mustard

The centerpiece of the whole museum is a display called the Great Wall of Mustard. Thousands of jars cover the wall, arranged by state and country of origin.

You can browse mustards from Japan, Australia, France, Germany and South Africa without moving more than a few steps. Rare varieties sit right next to everyday squeeze bottles.

New mustards keep arriving from around the world, so the wall grows every year.

Watch a mustard movie, then quiz yourself

Downstairs, a big screen runs entertaining videos about mustard history in what the museum calls MustardPiece Theatre. Past titles include “Mustard: The Spice of Nations.”

After the show wraps, you can step over to the Food Whiz quiz kiosk and test what you actually learned. The quiz works for kids and adults alike.

Vintage mustard advertisements and antique tins fill the walls around you, so there’s plenty to look at between screens.

Sterling silver mustard pots from another era

One display case holds the Gibbons Collection, a set of antique sterling silver and porcelain mustard pots.

The family of James Arthur Gibbons donated the pieces, and they joined the museum’s permanent collection in 2000.

Gibbons spent years tracking down these pots, and each one tells you something about how people served mustard at their tables over the centuries.

You get a feel for just how long mustard has held a spot at the dinner table.

Enroll at Poupon U and grab a diploma

The museum runs its own fake university called Poupon U, complete with a school motto, fight songs and a pep rally chant. You can buy a novelty diploma with a humorous title and walk out with a degree in mustard.

The gift shop stocks Poupon U sweatshirts, mugs, hats and other gear with the school crest on it. The whole thing keeps the place loose and fun, and kids especially get a kick out of it.

Sample dozens of mustards at the tasting bar

Up at street level, a tasting bar lets you try dozens of mustards side by side.

You’ll find everything from classic yellow and spicy brown to fruit-infused and exotic blends you’ve never heard of.

The staff go by the title Confidential Condiment Counselors, and they’ll steer you toward flavors that match what you like.

Once you land on a favorite, the gift shop sells hundreds of varieties you can take home with you.

Mustard makers compete for gold medals every year

Since 1995, the museum has hosted the World-Wide Mustard Competition. Mustard makers from around the globe send in entries, and judges taste them blind.

The competition runs 18 categories, covering Dijon, honey, hot pepper, whole grain, fruit and more. Gold, silver and bronze medals go out to the top finishers, and one mustard earns the title of Grand Champion.

If you see a gold medal sticker on a jar in the gift shop, now you know what it means.

National Mustard Day shuts down the whole street

Every first Saturday of August, the museum throws National Mustard Day right on Hubbard Avenue. The tradition started in 1991 as a tiny gathering in a few parking stalls in Mount Horeb.

Now it closes down the street in Middleton and draws thousands. Live music plays while you eat bratwurst and pretzels and sample mustards at every booth.

Kids get a bouncy house, balloon animals and face painting. The next one falls on Saturday, Aug. 1, 2026, from 10 a.m. to 4 p.m., rain or shine.

Say the K-word and you’ll get honked at

The museum has what’s been described as an all-mustard vending machine. Mrs. Mustard’s Kitchen gives you cooking tips and recipes built around mustard.

A Saskatchewan-produced exhibit called “Canada’s Mustard is the World’s Mustard” breaks down global mustard seed production. And whatever you do, don’t say “ketchup.”

The founder has been known to give you a playful honk of shame for dropping the K-word. The museum has landed spots on The Oprah Winfrey Show, the Food Network and National Public Radio.

Middleton’s trails and lake sit right outside the door

Middleton is known as “The Good Neighbor City” and sits on the western border of Lake Mendota. The town has 27 miles of biking and hiking trails running through hundreds of acres of conservancy land.

Pheasant Branch Conservancy alone covers more than 500 acres of wetlands, prairies and forests. Downtown runs a weekly farmers’ market in warmer months, and you can walk the shops on foot.

The museum pairs well with a bigger trip to Madison, just a short drive east.
