Arena Cheese Inc.

Arena Cheese, one of Wisconsin's oldest factories, is located in the Wisconsin River Valley within the lush, green, rolling hills of the Spring Green area. It's the proud home of the original co-jack cheese. In the long-standing reputation for this "Wisconsin Original" created in 1979, Arena's cheesemakers have crafted co-jack in the same location with the same recipe and cheesemaking techniques since its discovery more than three decades ago. Look out for the mouse in front of the cheese and gift store.
