What the thing is
Parmigiano Reggiano is a hard, granular, unpasteurized cow’s milk cheese.
Where it came from
It originated in Emilia-Romagna and Lombardy. The earliest written record dates to 1254.
What it gets right
It enforces terroir through law. Every wheel must be made in Emilia-Romagna or Lombardy, from raw cow’s milk, aged at least 12 months, and inspected by hammer at 12 months.
What it gets wrong
It fails outside the EU. In the US, ‘Parmesan’ is unregulated, and widespread adulteration is documented.
Why it matters now
It is a working model of how place-based food protection can resist industrial dilution—while exposing the limits of that protection beyond EU borders.
Is it worth your time
Yes—if you care about food as a legal, geographical and sensory fact, not just a flavour.
