Where did parmesan cheese originate?

Parmesan cheese, or Parmigiano-Reggiano as it's officially known, originates from the Emilia-Romagna region of Italy.

More specifically, it is produced in the provinces of:

* Parma

* Reggio Emilia

* Modena

* Bologna (only a small portion)

* Mantova (only a small portion)

It's important to note that only cheese made within these areas and adhering to strict production standards can be called Parmigiano-Reggiano. Any cheese labeled simply "Parmesan" is likely a different, less regulated variety.
