Rich, organic 100% Jersey Milk is the secret to Larry Peter’s cheese. Larry raises his Jerseys on a farm just on the outskirts of Petaluma. The Petaluma Creamery, where Spring Hill Cheese is made, is the largest creamery in the area. Taking a tour (appointments required) is fascinating. At the creamery, where the cheese is made, is also the Petaluma Creamery Cheese Shop, where you can pick up cheese, as well coffee, fresh baked goods, Panini’s and BBQ, gourmet homemade ice cream, custom gift baskets, and many other specialty items.
