Special, Reserve. Extra. Can you tell from the way we talk about it that we're proud? We start with four simple, natural ingredients including our high-quality, farm-fresh milk. Then for more that 15 months, we naturally age every nibble of Tillamook Special Reserve Extra Sharp Cheddar, which gives it a strong and complex flavor. Feature it on cheese boards, and add it to homemade sauces (if you're looking to show off).
