The brothers behind Quattro Portoni Dairy created a sustainable farm in their hometown and overhauled their business to raise buffalo instead of cattle. In 2006, they decided to produce cheese and today make over 25 varieties following traditional Lombardian styles. Their Casatica® di Bufala, made with 100% buffalo milk, is a soft-ripened cheese that highlights the best qualities of the milk. The shape and size were chosen to give it a better shelf life.
