Queso Buruaga Arditegia D.O. Idiazabal is a traditional Spanish cheese produced by Buruaga Arditegia S.L.U.

This cheese is crafted in the Basque region and holds the D.O. (Denominación de Origen) Idiazabal, a certification guaranteeing its origin and quality. It is made from the raw milk of Latxa and Carranzana sheep, known for their rich and aromatic milk.

The cheese is typically firm and slightly dry, displaying a nutty, buttery flavor with a hint of smokiness, often achieved through a careful aging process in which the cheese may also be smoked over beechwood.
