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