Blue Cheese
Definition and Scope
Blue cheese is a category of cheeses characterized by visible blue-green veins of mold. These veins are created by Penicillium cultures introduced during production. The mold thrives in oxygen-rich environments within the cheese. This category includes varieties like Roquefort, Gorgonzola, and Stilton.
These cheeses are defined by their intentional mold inoculation and aging process. The scope ranges from soft and creamy to hard and crumbly textures. Salinity levels also vary significantly between different blue cheeses. They represent a distinct branch in cheese taxonomy due to their unique biological ripening agent.
Production Process
Blue cheese production begins with standard cheese milk coagulation. Penicillium roqueforti spores are added to the milk or curds before forming. The curds are loosely packed to create air channels for mold growth. Wheels are then pierced with needles to introduce oxygen throughout.
The piercing creates pathways for air to reach the interior mold spores. Aging occurs in temperature and humidity-controlled environments for several weeks to months. During this period, the mold develops characteristic blue veining. The final product’s texture and flavor intensity depend on aging duration.
Sensory Profile
Blue cheeses deliver a pronounced sharp and salty flavor profile. They typically carry pungent aromas that can range from earthy to metallic notes. The mold contributes a distinct tanginess that balances the richness of the cheese base. Texture varies from creamy and spreadable to firm and crumbly.
Flavor complexity develops through lipid and protein breakdown by mold enzymes. Younger blue cheeses tend to be milder and creamier than aged versions. The salt content enhances flavor perception and controls mold development. The overall sensory experience is bold and assertive compared to other cheese categories.
Culinary Applications
Blue cheese serves as a standout component in salads and dressings. Its bold flavor pairs well with sweet elements like honey and fresh fruits. The cheese melts effectively for sauces and gourmet burger toppings. It is commonly crumbled over steaks and incorporated into compound butters.
In cooking, blue cheese adds depth to soups and savory pastries. It complements robust red wines and fortified wines like port. The cheese can be served at room temperature to maximize flavor release. Its strong character means it is often used sparingly as a flavor accent.
Regional Examples
Roquefort from France is a sheep’s milk blue aged in natural limestone caves. It holds AOC protected status and features a moist, crumbly texture. English Stilton is a protected name for blue cheese made in three counties. It has a cylindrical shape and milder flavor than Roquefort.
Italian Gorgonzola comes in two varieties: dolce (sweet) and piccante (sharp). Spanish Cabrales is a potent blue aged in natural caves in the Asturias region. Danish Blue is a widely exported cow’s milk variety with regular veining. Each regional example reflects local production traditions and terroir influences.
