AOP: Protected Designation of Origin
AOP (PDO in English) is the holy grail of terroir. It guarantees that the cheese is produced according to recognized savoir-faire, in a specific geographical area and with local ingredients. For Beaufort or Reblochon, this means cows can only eat grass in summer and hay in winter, prohibiting any fermented feed (silage) that would alter the taste of the milk. It is the promise of absolute traceability from the farm to your plate.
