Blue cheese, with its pungent aroma and distinctive veining, is a culinary paradox. It’s a food that simultaneously repels and attracts, intriguing adventurous palates and challenging the less daring. But how did this seemingly accidental creation come to be? The story of blue cheese is a fascinating blend of chance, observation, and the magic of microbial activity.
The Accidental Discovery: A Cheese Cave Tale
The prevailing narrative surrounding the origins of blue cheese revolves around a common theme: accident and neglect. While pinpointing the exact moment and individual responsible for its creation is impossible, the general consensus points to the Middle Ages, likely in France.
The story often involves a cheesemaker, perhaps in a region like Roquefort, France, who left a loaf of rye bread in a cheese cave – a cool, humid environment ideal for aging cheese. The bread, inevitably, became moldy. This mold, Penicillium roqueforti, is the key ingredient in blue cheese, the very microbe that gives it its signature veins and flavor.
The cheesemaker, returning to the cave sometime later, might have found the mold flourishing on both the bread and the cheese. Perhaps out of desperation, curiosity, or simply a lack of other options, they sampled the mold-laden cheese. What they discovered, surprisingly, was a new and interesting flavor profile.
This accidental introduction of Penicillium roqueforti spores into the cheese was the beginning of blue cheese as we know it. The cool, humid caves provided the perfect conditions for the mold to thrive, creating the characteristic blue veins and imparting its distinctive, pungent taste.
Understanding *Penicillium Roqueforti*: The Magic Behind the Mold
Penicillium roqueforti is more than just a random mold; it’s a carefully cultivated and controlled fungus. It belongs to the Penicillium genus, a group of molds that are also used in the production of other foods and medicines, most famously penicillin.
This specific strain, however, has a unique relationship with cheese. When introduced to cheese curds, Penicillium roqueforti breaks down the fats and proteins within the cheese matrix. This process, known as proteolysis and lipolysis, results in the formation of a variety of compounds that contribute to the characteristic flavor and aroma of blue cheese.
The blue veins themselves are a direct result of the mold’s growth. As the mold metabolizes within the cheese, it creates pockets and channels. These channels are also crucial for air circulation, further promoting the mold’s growth and development. The availability of oxygen is essential for Penicillium roqueforti to thrive and impart its signature flavor.
Without Penicillium roqueforti, there would be no blue cheese. Its controlled and predictable activity is what transforms ordinary cheese into a pungent, complex, and sought-after delicacy.
The Roquefort Legacy: Cave-Aged Perfection
Roquefort cheese holds a special place in the history and production of blue cheese. Produced exclusively in the Roquefort-sur-Soulzon region of France, it is legally protected by Appellation d’Origine Contrôlée (AOC) status. This means that only cheese made according to specific traditional methods and aged in the natural Combalou caves of Roquefort-sur-Soulzon can be labeled as Roquefort.
The Combalou caves are a key element in Roquefort’s unique character. These caves are naturally ventilated by “fleurines,” fissures in the rock that allow cool, humid air to circulate. This specific environment is crucial for the growth and development of Penicillium roqueforti.
The traditional Roquefort production process involves several key steps. Raw sheep’s milk is used, and the curd is carefully handled to create open spaces within the cheese. Penicillium roqueforti spores, often grown on rye bread, are then introduced to the cheese. The cheeses are then aged in the Combalou caves for a minimum of 90 days, allowing the mold to develop and impart its characteristic flavor.
Roquefort serves as a benchmark for other blue cheeses, demonstrating the impact of terroir – the unique environmental conditions of a specific region – on the final product. The unique cave environment, combined with traditional production methods, contributes to Roquefort’s distinct flavor profile, making it a prized and protected culinary treasure.
Beyond Roquefort: A World of Blue Cheese Varieties
While Roquefort is arguably the most famous blue cheese, it is far from the only one. Many other regions around the world have developed their own unique varieties, each with its distinct flavor and texture. These cheeses often differ in terms of the type of milk used (cow, goat, or sheep), the specific strain of Penicillium employed, and the aging environment.
Gorgonzola, from Italy, is another well-known blue cheese. There are two main types: Gorgonzola Dolce (sweet) and Gorgonzola Piccante (spicy). Gorgonzola is made from pasteurized cow’s milk and aged for varying lengths of time, depending on the desired intensity of flavor.
Stilton, from England, is a crumbly blue cheese made from cow’s milk. It has a protected designation of origin (PDO), meaning it can only be produced in the counties of Derbyshire, Leicestershire, and Nottinghamshire using specific traditional methods.
Cabrales, from Spain, is a strong, pungent blue cheese traditionally made from a blend of cow, goat, and sheep’s milk. It is often aged in caves in the Picos de Europa mountains, where it develops its characteristic intense flavor.
These are just a few examples of the diverse range of blue cheeses available worldwide. Each variety offers a unique sensory experience, reflecting the specific ingredients, techniques, and environments used in its production.
The Modern Production of Blue Cheese: Balancing Tradition and Technology
While the accidental discovery of blue cheese may have been serendipitous, its modern production is a carefully controlled process that balances traditional techniques with modern technology.
Today, cheesemakers often use freeze-dried Penicillium roqueforti cultures to inoculate the cheese. This allows for greater control over the mold’s growth and ensures consistent quality.
Salting is another crucial step in the production process. Salt helps to control the growth of unwanted bacteria and fungi, while also drawing out moisture from the cheese, contributing to its texture and flavor.
Piercing the cheese with needles is a common practice used to create air channels, allowing oxygen to penetrate the interior and promote the growth of Penicillium roqueforti. This is particularly important for cheeses that are not naturally aged in caves with good air circulation.
Aging remains a critical factor in the development of blue cheese. Cheesemakers carefully monitor temperature and humidity to create the ideal environment for the mold to thrive and impart its characteristic flavor. The length of aging also varies depending on the desired intensity of flavor and texture.
While modern technology has streamlined and standardized some aspects of blue cheese production, the fundamental principles remain the same. Cheesemakers still rely on the magic of Penicillium roqueforti to transform ordinary cheese into a complex and flavorful delicacy.

What is the generally accepted origin story of blue cheese?
The most common origin story of blue cheese is rooted in accidental discovery. Legend has it that a young shepherd, possibly in Roquefort, France, left his lunch of bread and cheese in a cave. Returning later, he found that the cheese had been transformed by mold. Too hungry to resist, he tasted it and found it unexpectedly delicious, thus discovering the magic of blue cheese.
While the exact details are likely embellished, the core concept highlights the importance of environmental conditions. The damp, cool caves of regions like Roquefort provided the perfect environment for Penicillium mold to flourish, unintentionally turning ordinary cheese into the unique delicacy we know today. This element of chance and adaptation is central to the cheese’s historical narrative.
What type of mold is responsible for the characteristic blue veins in blue cheese?
The primary mold responsible for the distinctive blue or green veins and flavor of blue cheese is a species of Penicillium. The most common species used is Penicillium roqueforti, although other species like Penicillium glaucum are used in some varieties. These molds are carefully cultivated and added to the cheese during production.
The mold’s growth within the cheese is facilitated by piercing the cheese with needles, allowing air to circulate and promote mold development. As the mold grows, it breaks down proteins and fats in the cheese, releasing volatile compounds that contribute to the unique aroma and pungent, sometimes spicy, flavor profile characteristic of blue cheese.
How does the environment, particularly caves, contribute to the production of blue cheese?
The traditional production of many blue cheeses, especially those from Europe, relies heavily on the unique environment provided by caves. These caves offer naturally cool, humid conditions that are ideal for the growth of Penicillium molds. The specific microflora present in these caves can also contribute to the distinctive flavor profiles of different blue cheeses.
The constant temperature and humidity within the caves help to regulate the cheese aging process, preventing it from drying out too quickly and allowing the mold to develop evenly throughout the cheese. While modern cheesemakers can replicate these conditions artificially, the traditional cave aging process is still considered essential for producing the highest quality blue cheeses, imparting a unique terroir-driven character.
What are some of the most famous varieties of blue cheese, and what distinguishes them?
Some of the most renowned blue cheeses include Roquefort, Stilton, and Gorgonzola. Roquefort, from France, is made from sheep’s milk and aged in the natural caves of Roquefort-sur-Soulzon.
