It involves a deep understanding of microbiology, precise control over the cheese-making environment, and patience, as the cheese ages to perfection. In this article, we will delve into the world of blue cheese production, exploring how the mold that characterizes this cheese type is introduced and cultivated.
Introduction to Blue Cheese Production
The production of blue cheese begins similarly to other types of cheese, with the curdling of milk. However, it’s the subsequent steps that differentiate blue cheese from other varieties. The critical factor in blue cheese production is the introduction of a type of mold, typically Penicillium roqueforti, which is responsible for the characteristic blue-green veins and the robust, tangy flavor of the cheese.
The Role of Mold in Blue Cheese
Mold plays a crucial role in the development of blue cheese. It breaks down the fats in the cheese, contributing to its flavor and texture. The mold is introduced into the cheese either by injecting it into the curd or by allowing the cheese to come into contact with mold spores in a controlled environment. The environment in which the cheese is aged is critical, as it must be maintained at a specific temperature and humidity level to encourage the growth of the mold without allowing it to overpower the cheese.
Types of Mold Used in Blue Cheese Production
While Penicillium roqueforti is the most commonly used mold in blue cheese production, other types of mold can also be used, depending on the specific variety of blue cheese being made. For example, Penicillium glaucum is often used in the production of Gorgonzola. Each type of mold imparts a unique flavor and texture to the cheese, making the selection of mold a critical step in the cheese-making process.
The Process of Introducing Mold into Blue Cheese
The introduction of mold into blue cheese can be achieved through several methods, each suited to the specific type of cheese being produced. The primary methods include:
- Injection: In this method, a solution containing the mold culture is injected directly into the cheese. This method is often used for cheeses like Roquefort and Stilton, where a uniform distribution of mold is desired.
- Salting: Some blue cheeses are salted with a mold culture, allowing the mold to penetrate the cheese as it ages.
- Environmental Exposure: In this approach, the cheese is aged in an environment where it is exposed to mold spores. This method is more traditional and relies on the natural presence of mold in the aging environment.
Controlled Aging Environment
Regardless of the method used to introduce the mold, the aging environment is crucial for the development of blue cheese. The cheese must be aged in a cool, humid environment to slow down the growth of the mold and allow it to penetrate the cheese uniformly. The aging process can take several months to a few years, during which time the cheese is regularly turned and monitored to ensure that the mold grows evenly and that the cheese develops the desired flavor and texture.
Maintenance and Monitoring
During the aging process, the cheese is maintained in a controlled environment with precise temperature and humidity levels. It is also regularly monitored for signs of over-molding or contamination, which can ruin the cheese. Skilled affineurs (cheese agers) play a crucial role in this process, as they must balance the growth of the mold with the development of the cheese’s flavor and texture.
Challenges in Blue Cheese Production
Producing high-quality blue cheese is not without its challenges. One of the primary concerns is the risk of contamination with unwanted mold species, which can impart off-flavors or even make the cheese unsafe to eat. Additionally, achieving a consistent flavor and texture can be difficult, as it depends on a variety of factors including the quality of the milk, the type of mold used, and the aging conditions.
Innovations in Blue Cheese Production
Despite these challenges, innovations in cheese-making technology and microbiology are continually improving the process of blue cheese production. For example, the development of more resilient and consistent mold cultures has reduced the risk of contamination and improved the uniformity of the final product. Furthermore, advances in aging technology have allowed for more precise control over the aging environment, enabling cheese-makers to produce blue cheese with a wider range of flavors and textures.

What is blue cheese and how is it made?
Blue cheese is a type of cheese that has been infused with a type of mold, typically from the species Penicillium. The process of making blue cheese begins with the creation of a base cheese, which can be made from cow’s, sheep’s, or goat’s milk. The milk is first pasteurized and then mixed with a starter culture that converts the milk sugar into lactic acid, causing the milk to curdle. The curds are then separated from the whey and shaped into their desired form.
The introduction of mold is the key step in making blue cheese. The mold is typically introduced into the cheese through a process called “needling,” where the cheese is pierced with a needle to create small holes that allow oxygen to penetrate the cheese. The mold is then introduced into these holes, where it begins to grow and break down the fats and proteins in the cheese. As the mold grows, it gives the cheese its characteristic blue or green veins and a strong, pungent flavor. The cheese is then aged for several months, during which time the mold continues to grow and the flavors mature.
What types of mold are used to make blue cheese?
The type of mold used to make blue cheese can vary depending on the specific type of cheese being made. The most common type of mold used is Penicillium roqueforti, which is used to make cheeses such as Roquefort and Gorgonzola. Other types of mold, such as Penicillium glaucum and Penicillium candidum, are also used to make different types of blue cheese. Each type of mold has its own unique characteristics and flavors, which are reflected in the final product.
The choice of mold will depend on the desired flavor and texture of the cheese. Some molds, such as Penicillium roqueforti, produce a strong, pungent flavor, while others, such as Penicillium candidum, produce a milder flavor.
