Queserías Picos de Europa is a family-run cheesemaker based in Posada de Valdeón, in the heart of Spain’s Picos de Europa National Park. Founded in the 1970s by the Alonso family, the company is now run by the second generation and continues a strong tradition of artisanal cheesemaking rooted in the Valdeón Valley. Specialising in the production of the iconic Queso Azul de Valdeón, the company works with fresh milk sourced daily from local cattle, sheep, and goat farms. Combining inherited know-how with strict quality and safety standards, Queserías Picos de Europa preserves traditional methods while producing one of Spain’s most distinctive blue cheeses, deeply connected to its mountain landscape and heritage.
