Ellsworth Cooperative Creamery in Wisconsin makes natural White Cheddar Cheese Curds taste like no other because they are crafted with only rBST free milk from 450 family farms throughout Wisconsin and Minnesota. This unique packaging process produces the freshest tasting curds, tested to have a shelf life that exceeds 6 months when kept refrigerated and unopened. The oxygen is taken out of the bags yet the cheese remains loosely packaged. The longer the cheese remains inside the sealed/unopened package, the more enriched the cheddar flavor becomes.
