Widmer's Cheese Cellars in Theresa, Wisconsin, traces its roots back to 1922 when Swiss immigrant John O. Widmer established the operation after working as an apprentice in the region’s cheese industry. The company continues to apply techniques handed down through several generations, focusing on quality and consistency. Its flagship product, Wisconsin Brick cheese, is produced in limited quantities to preserve a distinctive earthy sweetness and a texture that lends itself to both table service and culinary use.
