National Mustard Day

media release: Get ready to spread the love! National Mustard Day returns on Saturday, August 2, 2025, and this year’s celebration is shaping up to be the zestiest yet. Hosted by the world-famous National Mustard Museum, the annual condiment extravaganza brings together food, fun, flavor, and fundraising in a full-day festival that’s not to be missed.

This year, we’re proud to unveil Mustard Mosaic — a new community-wide campaign running through July and culminating on National Mustard Day. In this spirited collaboration, local restaurants, cafes, and bars are crafting unique mustard-inspired food and drink items, donating a portion of proceeds to support the nonprofit National Mustard Museum’s exhibits, outreach, and educational programs. It's flavor with a purpose — and a delicious way to give back.

National Mustard Day Festival Highlights – Saturday, August 2

From 10:00 AM to 4:00 PM, downtown Middleton will transform into a mustard-lover’s paradise with:

Hot dogs, bratwursts, and hot soft pretzels!

The fan-favorite Razzle Dazzle Mustard Ice Cream from Chocolate Shoppe

Live music on the French’s Mustard Stage from Alpha Romeos and the Red Hot Horn Dawgs

Kids Are People Too! interactive family entertainment

Face painting, wacky games, giveaways, and mustard-themed merchandise

A 50/50 raffle drawing at 4:00 PM to benefit the Museum

And yes — as always, ketchup is strictly prohibited on festival grounds.

See the Museum’s New Look!

Visitors will also be among the first to experience the newly refreshed and reimagined National Mustard Museum, which has undergone a recent glow-up — updated exhibits, new signage, and enhanced displays make this beloved landmark better than ever. The Gourmet Gift Shop and free Ultimate Mustard Tasting Bar will be open.  Plus, don't miss a chance to sample award-winning mustards from the World-Wide Mustard Competition.
