Organic Grass Fed Classic Mild Cheddar Macaroni & Cheese The same delicious taste of our Organic Classic Mild Cheddar with the goodness of cheese made with milk from grass fed, California cows with year round access to pasture. The cheese used in Annie’s Organic Grass Fed Shells & Real Aged Cheddar comes from the Rumiano Family. All Rumiano organic milk producers are certified through the American Humane Association’s Free Farmed Certified program, which guarantees customers that the organic milk used in the making of Rumiano organic cheeses comes from cows that are raised and treated humanely.
