Tillamook Medium Cheddar wins Best Medium Cheddar in the World at the 2010 World Cheese Championship Cheese Contest in Madison, Wisconsin! The Tillamook Cheese Factory has been producing great cheese for more than 100 years. Starting with only a desire for good cheese and a few cows, Tillamook Cheese is now produced on a grand scale. Nurtured with nothing more than the clean air of Oregon’s Pacific Coast, milk from Tillamook County cows produces some of the best cheese you will ever eat. All cheeses are naturally aged and produced with milk from cows not supplemented with artificial growth hormones (rBST).
