Can Parmigiano Reggiano PDO be stored outside the refrigerator?
Preferably not. If it is packaged it can be stored up to a temperature of 10/14 degrees, but the lower the temperature the better the product keeps, and oxidation is prevented as are other phenomena like moulds and contamination. To store Parmigiano Reggiano PDO correctly wrap in a white odourless cloth and place in the least cold part of the fridge.
