Blue Mold Cheese

Definition and Scope

Blue mold refers to specific strains of Penicillium fungi intentionally introduced during cheesemaking. These molds create characteristic blue-green veins and contribute to unique flavor development. The category includes cheeses like Roquefort, Gorgonzola, and Stilton.

These cheeses undergo specific production methods allowing oxygen exposure for mold growth. The mold distribution creates marbled patterns throughout the paste. Blue cheeses represent a distinct category within cheese taxonomy defined by this intentional mold colonization.

Production Process

Blue mold cheeses begin with milk inoculated with Penicillium roqueforti or similar cultures. The curds are loosely packed to create air channels. This porous structure enables oxygen circulation essential for mold development during aging.

Cheesemakers typically pierce the cheese wheels with needles to introduce oxygen. This piercing creates pathways for mold growth throughout the interior. Temperature and humidity controls during aging precisely manage mold expansion and flavor development.

Sensory Profile

Blue mold cheeses exhibit sharp, salty, and piquant flavors with earthy undertones. The mold contributes peppery notes and distinct umami characteristics. Texture ranges from crumbly to creamy depending on moisture content and aging duration.

Aromatic compounds create bold, complex bouquets often described as pungent or spicy. The blue veins contribute tangy flavors that balance the rich, buttery paste. These sensory properties make blue cheeses immediately recognizable.

Culinary Applications

Blue cheeses serve as standout components in salads, dressings, and sauces. Their strong flavors allow them to pair well with sweet accompaniments like honey and fruits. They melt effectively for use in cooked dishes and gourmet burgers.

These cheeses complement robust red wines and dessert wines in pairing scenarios. Crumbled blue mold cheese enhances vegetable dishes and meat preparations. Their intense flavor means small quantities can significantly impact finished dishes.

Regional Examples

Roquefort from France uses sheep’s milk and ages in natural limestone caves. This protected designation of origin cheese features moist, crumbly texture and sharp saltiness. Its veins display particularly vibrant blue-green coloring.

Italian Gorgonzola offers both dolce (sweet) and piccante (sharp) varieties. English Stilton maintains a Protected Designation of Origin status requiring specific production methods. These regional examples demonstrate how terroir influences blue mold cheese characteristics.
