Formaggio di Fossa di Sogliano PDO, is a hard or semi-hard cheese produced with whole cow’s milk or sheep’s milk, or with a mix of the two (80% cow and at least 20% sheep). The animals must originate from farms within the production area and must belong to the following breeds: Frisona Italiana, Bruna Alpina, Pezzata Rossa cattle breeds and their crossbreeds; Sarda, Comisana, Massese, Vissana, Cornella Bianca, Fabrianese delle Langhe, Pinzirita sheep breeds and their crossbreeds.
The milk, which is obtained from two daily milkings, can be used both raw and pasteurised; if raw, it must be processed within 48 hours of the first milking. Curdling takes place with the addition of natural rennet, at a temperature of 30-38°C. After the curd has broken and the cheese mass has been put in molds, it is salted and then pre-ripened for a period of between 60 and 240 days. The cheese forms are then inserted into natural cotton bags and buried in characteristic sandstone pits. Before use, the pits are sterilized with fire and smoke, by burning small quantities of straw, and a raised platform of untreated wooden planks is placed at the bottom. The walls of the pit are lined with a layer of straw supported by vertical reed fencing. Once the forms have been introduced, they are covered with straw and the pits are covered with a wooden cover, which is sealed with clay or lime sandstone mortar. The cheeses are removed from the pits after 80-100 days.
