How Blue Cheese is Made

Blue cheese is a type of cheese that is well-known for its distinct blue veins or spots. It is a versatile cheese that can be enjoyed on its own, crumbled on salads, and used as a flavoring agent in various dishes. The process of making blue cheese is an intricate one that requires patience and precision. In this blog post, we will take a closer look at the blue cheese-making process and answer some frequently asked questions about this delicious cheese.

What is Blue Cheese?

Blue cheese is a type of cheese that is made by introducing mold spores into the cheese. These mold spores, known as Penicillium roqueforti, are responsible for the blue veins or spots that are characteristic of blue cheese. The mold spores grow throughout the cheese and give it a distinct flavor and aroma.

Blue cheese is typically made from cow’s milk, although sheep’s milk and goat’s milk can also be used. The cheese is aged for several months, during which time the mold spores grow and develop.

History of Blue Cheese

The history of blue cheese dates back to the 7th century, when it was first made in the Roquefort region of France. Legend has it that a young shepherd accidentally left his lunch of bread and cheese in a cave while he went to tend to his flock. When he returned, he found that the cheese had developed blue veins and had a unique flavor. This was due to the mold spores that were present in the cave.

Over time, the process of making blue cheese became more refined, and it became a popular cheese throughout Europe. Today, blue cheese is enjoyed all over the world and is made in many different countries.

Ingredients Needed for Making Blue Cheese

To make blue cheese, you will need the following ingredients:

  • Milk: Blue cheese is typically made from cow’s milk, although sheep’s milk and goat’s milk can also be used. The milk should be fresh and of good quality.
  • Starter culture: This is a mixture of bacteria that is added to the milk to start the cheese-making process. The bacteria help to acidify the milk and create the right environment for mold spores to grow.
  • Rennet: This is an enzyme that is added to the milk to coagulate it and form curds.
  • Penicillium roqueforti: This is the mold spore that is responsible for the blue veins or spots in blue cheese. It is added to the cheese during the cheese-making process.

The Blue Cheese-making Process

The blue cheese-making process is a multi-step process that requires patience and precision. Here are the steps involved in making blue cheese:
 

Step 1: Heating the Milk

  • The first step in making blue cheese is to heat the milk to the right temperature. The temperature will depend on the type of milk you are using and the recipe you are following. Generally, the milk is heated to around 86°F (30°C).

Step 2: Adding the Starter Culture

  • Once the milk has been heated, the starter culture is added. The starter culture is a mixture of bacteria that helps to acidify the milk and create the right environment for mold spores to grow. The culture is typically added in small amounts and then stirred into the milk.

Step 3: Adding Rennet

  • After the starter culture has been added, rennet is added to the milk. Rennet is an enzyme that helps to coagulate milk and form curds. The amount of rennet added will depend on the recipe you are following and the type of milk you are using. The rennet is typically added in small amounts and then stirred into the milk.

Step 4: Cutting the Curds

  • Once the milk has coagulated, the curds are cut into small pieces. This helps to release the whey and separate it from the curds. The size of the curds will depend on the recipe you are following and the type of cheese you are making.

Step 5: Draining the Whey

  • After the curds have been cut, the whey is drained from the cheese. This is typically done by pouring the mixture into a cheesecloth-lined colander. The cheese is then left to drain for several hours, during which time the curds will continue to firm up.

Step 6: Salting the Cheese

  • Once the whey has been drained, the cheese is salted. Salt is added to the cheese to help preserve it and give it flavor. The amount of salt added will depend on the recipe you are following and the type of cheese you are making.

Step 7: Adding the Mold Spores

  • After the cheese has been salted, the mold spores are added. The mold spores, known as Penicillium roqueforti, are responsible for the blue veins or spots in blue cheese. The mold spores are typically added by mixing them with a small amount of water and then brushing or injecting them into the cheese.

Step 8: Aging the Cheese

  • Once the mold spores have been added, the cheese is left to age. Blue cheese is typically aged for several months, during which time the mold spores grow and develop. The cheese is stored in a cool, humid environment to encourage the growth of mold spores. During the aging process, the cheese is turned and brushed to ensure that the mold spores grow evenly throughout the cheese.
