Ossau

Ossau-Iraty is a Basque cheese made from sheep's milk. Ossau-Iraty or Esquirrou is produced in south-western France, in the Northern Basque Country and in Béarn. Its name reflects its geographical location, the Ossau Valley in Béarn and the Irati Forest in the Basque Country. It has been recognized as an appellation d'origine contrôlée product since 1980. It is one of three sheep's milk cheeses granted AOC status in France (the others are Roquefort and Brocciu). It is of ancient origin, traditionally made by the shepherds in the region.
