Afuega'l pitu is an unpasteurised cow's milk cheese from Asturias, one of two Asturian cheeses (The other being Cabrales) to have been recognized with Protected Denomination of Origin (DOP-Denominación de Origen Protegida) by the European Union.
The name comes from its tendency to stick to a person's palate ("pitu") . It is considered to be one of the oldest Spanish cheeses. Production is centred around the municipalities of Grado, Las Regueras, Morcín, Pravia, Riosa, Salas, and Yernes y Tameza with the municipality of Grado having the largest production and being the headquarters of the council of Denomination of Origin.
The cheese is produced all year long although principally in spring and winter due to the elevated fat content in milk in the spring and winter months.
The cheese is made from cow's milk from cows milked in the afternoon or evening and heated between 25º C and 30º C (77-86ºF) with a coagulant added so the milk forms curds. After midday the following day, the curds are cut and deposited in a mold to drain. From the mold it is passed to a sack or bag ("Fardela") for the "Trapu" version or left with the form given by the mold ("Troncado"-Trunk) like a bishop's mitre. Salt is added, as is paprika (pimentón) if desired. After a few days the period of curing starts with aging occurring on wooden planks for a period between a week and several months.
The resulting cheese is normally white (blanco), with a red (rojo) variety is also made where paprika (pimentón) and/or cayenne pepper are added to the cheese before moulding to shape using the form ("Troncado"-Trunk) or cloth bag ("Trapo" o "Trapu").
It also comes in soft and semi-hard varieties depending on the duration of curation.
