Grana (cheese) in the context of "Parmesan"

Parmesan (Italian: Parmigiano Reggiano, pronounced [parmiˈdʒaːno redˈdʒaːno]) is an Italian hard, granular cheese produced from cow's milk and aged at least 12 months. It is a grana-type cheese, along with Grana Padano, the historic Granone Lodigiano [it], and others.

The term Parmesan may refer to either Parmigiano Reggiano or, when outside the European Union and Lisbon Agreement countries, a locally produced imitation.
