It is the position of the OU’s poskim (halachic authorities) that one need only wait between eating aged cheese and meat if the cheese is of a variety that is intentionally aged in production, such as Parmesan (must be aged in production at least 10 months) and Emmental (much be aged in production at least 6 months). Please see OU Aged Cheese List (https://oukosher.org/blog/consumer-kosher/aged-cheese-list/). One need not wait after consuming non-aged cheese that is then incidentally aged on refrigerator shelves and exhibits the same texture and taste as it should exhibit in in its non-aged state.
However, it has come to our attention that some non-aged cheeses, if left to age in their packaging, may acquire a meshichas ta’am – a very potent taste – which is one of the factors that requires a person to wait after certain cheeses. (V. Taz. s.k. 4 and other poskim on Shulchan Aruch Yoreh 89:2.) Should a person notice that an otherwise non-aged cheese which has aged after production presents a very potent taste, or that it has acquired a brittle texture similar to that of aged cheeses, he should treat such cheese the same as regular aged cheese and wait the full period before consuming meat.
