How long must Gruyère cheese be aged at minimum?

Gruyère cheese must be aged for a minimum of six months, which is why the choice indicating 6-12 months is accurate. This aging process allows the cheese to develop its distinct flavor, which is nutty and slightly sweet, along with a firm texture. The minimum six-month aging also plays a crucial role in the development of its characteristic aroma and the formation of its unique crust.

Cheeses that are aged for shorter periods would not have the same flavor profile and texture as those that have undergone the full aging process. Hence, while Gruyère can be aged much longer, a six-month aging period is required to meet the specific standards that define the cheese's quality and identity.
