Idiazabal is a traditional, farmhouse, hard cheese made from raw milk of Latxa or Carranza sheep in the Basque and Navarra regions of northern Spain. Named after the village of Idiazabal, the cheese received Spanish D.O. (Denominacion de Origen) in 1987.
In summer, the sheep migrate to higher pastures to graze on the blossoming, new grass. During this time, the artisanal cheesemakers milk the sheep, make the cheese and leave it in the rafters to mature. At the end of summer when the cheesemakers return back to the lowlands with their sheep, the cheese has ripened and is ready for sale.
