Cello Romano Cheese is a delicious, creamy and Traditional Pecorino Romano is made from sheep’s milk, but our Cello version hails from the cow. Romano cheese has similarities to Parmesan, but the former has a bit of a sharper bite. This hard, crumbly cheese is aged no less than six months for that signature piquant flavor. Our Cello Romano showcases a cleaner finish than other American varieties and is gluten and rBGH/rbST free.
