What You See
Widmer's is best known for brick cheese, a washed-rind Wisconsin original, and for its cheddar and colby. The retail shop has a viewing area that looks onto the make room, and the cheesemakers will answer questions if you ask. Come outside the morning make and you still get samples, a picture tour of the process and a 15-minute video.
Opening Hours and Holidays
The shop opens Monday to Saturday from 7am to 5pm. From June to October it also opens on Sundays, 10am to 3pm. In 2026 it closed for Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas Day. Call (920) 488-2503 if you are driving a long way and want to be sure the vats are running.
Getting There
Theresa is a village in Dodge County, roughly an hour north-west of Milwaukee by car. There is no useful public transport, so plan to drive. The shop sits on Henni Street in the middle of the village.
Nearby
Henning's in Kiel and LaClare Family Creamery near Malone are both within about an hour, so you can see two factories in one morning if you start early. The factory tours roundup lists the rest.
