The name formai del mut means cheese from the mountain in the Val Brembana dialect, where the "mountain" refers to the alpeggio, the highland plateau pasture where the peasants take the cows in the summer time. A limited amount is produced, so this type of cheese is very rarely found outside its production zone. The cheese is produced from the milk of the Bruna (Brown) variety of cows, and the particular flavor of the formai del mut DOP comes from aromatic herbs found in the Alpine pastures, eaten by those cows, which have been raised in this area for centuries.
