Grana Padano is an Italian cheese originating in the Po Valley. It is similar to Parmesan but with less strict regulations governing its production. This hard, crumbly-textured cheese is made with unpasteurized cows' milk that is semi-skimmed. To preserve the authenticity of the manufacturing processes and raw materials used to make this cheese, Grana Padano was registered as a denominazione di origine controllata (DOC) in 1955, and as a European Union protected designation of origin (PDO) in 1996. Outside of the EU, its name is protected in several other countries based on the Lisbon Agreement and bilateral agreements.
