Many years ago, while in a trip of about a month, seems there was a power outage, and in the refrigerator, at my return, the simple kind of cheese changed from what it was to a very stinky, softer and much delicious type of cheese never tried before.

 

The event was well explained to me by a highly knowledgeable professional of the cheese industry. I barely remember details now.

 

To do it on purpose, what should be done to turn plain simple cheese into a 'fancy' or preferred or new type ?

Would 'seeding' the plain cheese with a bit of gouda, brie, or whatever is choice; and what temperature or other considerations would work ? Is there also a chance to become poisonous or unhealthy ?
