Cabrales is one of Spain’s most recognisable blue cheeses, but its identity comes from far more than blue-green veining. The PDO connects raw local milk, local production and maturation in natural caves in the Picos de Europa, where humidity and temperature favour Penicillium development. It may be made from cow milk alone or authorised combinations including sheep and goat milk, helping explain variation between cheeses.
Quick summary
| Milk | Raw cow milk or an authorised combination of cow, sheep and goat milk. |
|---|---|
| Maturation | In natural caves in the area; the regulatory council describes typical periods of two to four months. |
| Mould | Penicillium developing during maturation creates the blue-green veins. |
| Identification | Packaging, producer label and numbered PDO control label. |
What makes a blue cheese Cabrales
Not every Asturian blue cheese is Cabrales. The designation establishes a production area and process linked to specific municipalities. Milk comes from controlled farms within the area and the cheese must follow the certified process, including its most distinctive phase: maturation in natural caves.nnProtection of the name matters because many blue cheeses can look similar. Veins alone do not prove origin; traceability and PDO control identification are what make a cheese Cabrales PDO.
A distinctive feature: milk composition can vary
Modern Cabrales can be made from raw cow milk or an authorised mixture of two or three species among cow, sheep and goat. Historically, this reflected the milk available from mountain herds. During periods with less sheep and goat milk, cow milk naturally becomes more prominent.nnThis variation helps explain differences in intensity, fat, aroma and texture between producers and batches. It should not be mistaken for inconsistency; it forms part of the traditional framework permitted by the PDO.
What happens inside the caves
After production and initial drying, cheeses move into natural caves. The regulatory council describes very high humidity, around 90%, and cool temperatures that favour mould development. Penicillium grows through the paste and creates the characteristic blue-green areas.nnA cave is not merely a refrigerator. Humidity, airflow, handling and time shape proteolysis, texture and aroma, making cave maturation central to Cabrales identity rather than a decorative step after producing generic blue cheese.
Texture, aroma and pungency
Well-matured Cabrales has a paste that can range from cohesive to distinctly creamy, crossed by mould veins. The profile is intense and persistent, with saltiness, evolved dairy notes, cave character, noble mould and varying pungency. Cheeses containing sheep or goat milk may show particularly assertive character.nnA powerful aroma should not automatically be confused with spoilage. With blue cheese, knowing the normal style is essential for distinguishing intended mould from unexpected deterioration.
Serving it without overwhelming the tasting
Because Cabrales is intense, small portions work well. On a cheese board it generally belongs near the end so it does not overwhelm the palate before gentler cheeses. Let only the serving portion lose its refrigerator chill; very cold fat and paste feel firmer and aromas are less expressive.nnCabrales also works in cooking, although heat changes its profile and can amplify saltiness and aroma. For tasting the cheese itself, moderate portions and neutral bread make the paste easier to appreciate.
How to identify an authentic cheese
The regulatory council describes specific packaging and identification for Cabrales ready for sale, together with the producer label and numbered PDO control label. Cheese sold without the corresponding identification does not carry the denomination’s guarantee, even if it is informally described as “Cabrales”.nnOnline, inspect packaging and control-label photographs. Producer, milk composition and format are also useful information. The more traceability a product page shows, the less you have to rely on vague phrases such as “Asturian blue”.
Related questions
Is Cabrales always made from three milks?
No. It can be made from raw cow milk alone or authorised mixtures that include sheep and goat milk.
Do blue veins mean the cheese is spoiled?
Not in normal Cabrales. Penicillium development is part of the intended maturation. The key is distinguishing that characteristic mould from abnormal changes.

Bottom line
Cabrales is a cheese of territory and cave as much as it is a blue cheese. Possible milk combinations, natural cave maturation and official identification explain why blue veins alone are not enough to know what you are buying.
