Aging and quality
Parmigiano Reggiano must be aged at least 12 months to receive the mark of the Consortio.
According to experts a 12 months aging is not enought to have a good product: the cheese should be aged for at least 18 months, and it reaches its best aging between 20 and 30 months.
Some people also tried to age some wheels for 7 years… Surely, to bring the cheese to a so long aging, we must have a good product. In other words, aging is practically a quality mark; the longer it is, the best is the development of tastes and scents and the more is the cheese digestible, thanks to a natural process which take place during the maturation.
