Blue cheese, known for its distinctive veins of blue or blue-green mold, has been a favorite among cheese enthusiasts for centuries. The unique flavor and aroma of blue cheese are primarily attributed to this blue mold, which is not just aesthetically pleasing but also contributes significantly to the cheese’s character. But what exactly is this blue mold, and how does it end up in our beloved blue cheeses? In this article, we will delve into the world of blue cheese, exploring the origins, types, and roles of the blue mold, as well as the process of how it’s introduced into the cheese.
Introduction to Blue Mold
The blue mold found in blue cheese is a type of fungus, specifically belonging to the genus Penicillium. This genus includes a wide variety of species, some of which are used in the production of cheese, while others are known for their role in decomposition or as pathogens. In the context of blue cheese, the most commonly used species are Penicillium roqueforti and Penicillium glaucum. These fungi are harmless to humans when consumed and are what give blue cheese its characteristic strong flavor and pungent aroma.
History and Origins
The history of blue cheese dates back to the Middle Ages, with stories suggesting that the cheese was discovered by accident. According to legend, a wheel of cheese was left in a damp cave, where it was exposed to the fungi naturally present in the environment. Over time, the fungi grew within the cheese, transforming it into what we now recognize as blue cheese. The earliest recorded production of blue cheese was in Roquefort, France, from where Penicillium roqueforti gets its name. These early cheeses were made from sheep’s milk, a tradition that continues in the production of Roquefort cheese to this day.
Species of Blue Mold
While Penicillium roqueforti is the most well-known species used in blue cheese production, other types of mold can also be found in various blue cheeses. Penicillium glaucum, for example, is used in the production of Gorgonzola, an Italian blue cheese. The choice of mold can influence the final flavor and texture of the cheese, with different species imparting unique characteristics. The specific conditions under which the cheese is aged, including temperature, humidity, and exposure to air, also play a significant role in the development of the mold and the final product.
The Process of Introducing Blue Mold
The introduction of blue mold into cheese is a deliberate process that requires careful control to achieve the desired outcome. Cheese makers can introduce the mold spores into the cheese in several ways, including:
- Directly adding the mold spores to the curd before it is shaped and aged.
- Allowing the cheese to be exposed to the natural environment where the mold spores are present, though this method is less common and more unpredictable.
- Using a combination of these methods to achieve a consistent and desirable level of mold penetration.
The cheese is then aged under controlled conditions that encourage the growth of the mold. This can involve periodic turning of the cheese, adjustments in temperature and humidity, and sometimes piercing the cheese to allow oxygen to penetrate and facilitate mold growth.
Role of Blue Mold in Cheese Production
The blue mold plays a crucial role in the cheese production process, affecting not only the appearance but also the taste, aroma, and texture of the cheese. As the mold grows, it breaks down the fats in the cheese, producing compounds that contribute to the cheese’s strong, pungent flavor.
