The milk is produced by cows fed according to strict regulations that allow the use of grass grown only in the place of origin, together with natural animal feed.
Certain foodstuffs are strictly forbidden:
- any kind of silage (e.g. corn silage) or fermented food
- animal origin feed or any by-product of the food industry
The cows are milked twice a day and the milk is taken to the cheese house within two hours of each milking.
