Who knew that making Parmesan was so limited by location?

Is this the point where I get to make the really bad joke that making Parmesan brings in a lot of cheddar for Italy?

“A wheel of parmesan cheese can cost over $1,000.

“A single wheel takes at least one year to age, 131 gallons of milk to make, and it can only be made in a restricted area in northern Italy, in the region of Emilia Romagna.

“We visited a dairy in Parma, Italy to find out how the cheese is made and why it is so expensive.” – YT
