Why Parmesan Cheese Is So Expensive

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.
