Cabrales

Cabrales is a blue cheese made in the artisan tradition by rural dairy farmers in Asturias, Spain. This cheese can be made from pure, unpasteurized cow’s milk or blended in the traditional manner with goat and/or sheep milk, which lends the cheese a stronger, spicier flavor. All of the milk used in the production of Cabrales must come exclusively from herds raised in a small zone of production in Asturias, in the mountains of the Picos de Europa. The milk is first heated and curdled by the addition of rennet. The whey is removed from the curds, which are then packed into cylindrical molds called arnios, salted and left to cure and harden. After the initial curing period of around two weeks, the Cabrales is then aged a further two to five months in natural caves in the limestone mountains of the area. The cheeses are placed on wooden shelves known as talameras, where they are periodically turned and cleaned. Relative humidity in these caves is typically 90% and the temperature is a cool 7–13 °C (45–55 °F), conditions favoring the development of penicillium molds that produce blue-green veins throughout the cheese.
