Cabrales (Spanish: queso de Cabrales) is a cheese made in the artisan tradition by rural dairy farmers in the north of Spain. This cheese can be made from pure, unpasteurised cow’s milk or blended in the traditional manner with goat and/or sheep milk, which lends the cheese a stronger, more spicy flavor but is unavailable in winter.

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 moulds that produce blue-green veins throughout the cheese.

Cabrales has a strong flavour, sometimes quite acidic, which can be very complex when made with mixed milks. Like Gorgonzola and Roquefort, it is a famous blue cheese whose name is protected by European law.

Traditionally, Cabrales was sold wrapped in the moist leaves of Acer pseudoplatanus (Sycamore Maple), but nowadays regulations require that commercially produced Cabrales be sold in a dark-green-coloured aluminum foil with the registered official stamp of the PDO Queso de Cabrales. Within the production zone it is still possible to encounter Cabrales cheese with the traditional maple leaf wrapping, although it is only ever produced in small batches and not approved for export, as it is ineligible for DO status. The same is true of other Spanish blue cheeses, also traditionally leaf-wrapped, such as Valdeón and Picón Bejes-Tresviso.
