Smoked Idiazábal Cheese Olmeda Origenes from Arizkun Navarra. Made from the Latxa sheep’s milk, it is straw-coloured with an intense but mild aroma. The flavour of our Smoked Idiazabal Cheese is profound, wide and full with a touch of herbs and pasture with an aftertaste reminiscent of hay. Origin: Arizkum, Valle de Baztán, Navarra. Curing period: 5 months minimum.
