OK, probably not only in Switzerland. But certainly in Switzerland.
An automatic vending machine at the main train station in Gstaad that sells so-called “Alp-Cheese,” a very special type of cheese that is by law required to be made from the milk of cows that graze at very high altitudes in the Swiss Alps:
It’s on my to-do list to explore this topic further. From what I have been able to gather, there is an altitude defined by law above which the cows are required to graze; I’ve also read that the Swiss government pays a bonus to the farmers (per cow) as an incentive for them to keep this industry alive.
