The Pier Luigi Rosso Cheese Factory has its Head Office in Biella near the place where the Oropa Valley meets the Cervo Valley, in the centre of the Biellese alpine range. From the plain, our valleys resemble a majestic amphitheatre bordered to the west by the moraine bastion of the Serra, 25 kms long, and by the crests of Mombarone, and to the north and east by the imposing profiles of the alpine chain.
The middle and lower areas of the valleys, with hilly ridges rising above, form a vast green carpet where hundreds of small farms devoted to cattle - farming are to be found. In the westernmost area of the Biellese, in the upper Elvo Valley, home of the Rosso family, our ageing and ripening premises are located .
