Is There A Specific Cheese Culture For Blue Cheese?

Choosing the Right Mold Culture

When making blue cheese at home, selecting the right mold culture is crucial for success. Penicillium roqueforti is the primary culture used for blue cheese production. This mold thrives in low-oxygen environments, which is why it’s often injected into the cheese or wrapped in cheesecloth to facilitate growth. A good quality P. roqueforti culture can be purchased from reputable suppliers or obtained from an experienced cheesemaker.

Culturing Blue Cheese

To culture blue cheese, you’ll need to create an environment that allows the mold to grow. This typically involves mixing the P. roqueforti culture with a small amount of water or milk to create a spore suspension. The suspension is then added to the cheese, either by injecting it into the curd or by wrapping the cheese in cheesecloth that’s been inoculated with the culture. The cheese is then aged in a controlled environment, with temperatures between 10-15°C (50-59°F) and humidity levels around 80-90%.

Aging Blue Cheese

Aging blue cheese requires patience and a controlled environment. The cheese is typically aged for several months, with regular turning and monitoring of its development. During this time, the P. roqueforti culture will break down the fats and proteins in the cheese, producing compounds that give blue cheese its characteristic flavor and aroma. The aging process can be accelerated by increasing the temperature, but this may affect the quality of the final product.
