Parmigiano-Reggiano is a staple in many Italian American dishes. Its hard, gritty texture and fruity, nutty flavors amplifies any pasta dish it is sprinkled over, risotto it’s cooked in, or wine it is paired with. The cheese’s flavor sets it apart from all others, but that is not the only aspect that does. One wheel of parmesan can cost upwards of $1,000.

Its taste alone is arguably worth the steep price, but why is it so expensive? Each wheel takes 131 gallons of milk to make and at least one year to age. Most importantly, parmesan cheese can only be created within the region of Emilia Romagna in Northern Italy.
