Parmigiano Reggiano has been made the same way since the 12th century. Monks in the Po Valley monasteries developed the recipe: raw cow's milk, rennet, salt, time. Nothing else. No additives, no preservatives, no shortcuts. The result — after 12-36 months of aging — is the most complex, umami-rich, crystalline-textured cheese on Earth. You can watch it being made. Dozens of dairies (caseifici) across the Parma-Reggio Emilia area open their doors to visitors at 7am, when the cheesemakers pour 550 liters of milk into copper cauldrons and begin the transformation.

Plan my Parma food trip →Arrive at 7am. The cheesemaker heats the previous evening's skimmed milk with that morning's whole milk in huge copper vats. Rennet is added. The curd forms, is broken into rice-grain-sized pieces, cooked, and gathered into a linen cloth. Two wheels per vat. Each wheel uses 550 liters of milk from cows that eat only grass and hay — no silage (it's forbidden by the production rules). The wheels are salted in brine for 20 days, then aged for 12-36 months in vast cathedral-like warehouses where thousands of wheels sit on wooden shelves. The tasting follows: 24-month vs 36-month, and you'll understand why age matters.
