The smear is washed off the surface of the alpine cheese from Bernese Oberland when it is 5 to 7 months old. It then matures in a “Gaden” (storage room) at a temperature of approx. 12 degrees Celsius and a relative air humidity of 70% to 75% to become Berner Hobelkäse AOP. Its unique aroma is owed to the lush alpine meadows, the traditional production methods and the special storage.
