Why Cheese Have Holes?

Basically, a bacteria is responsible for the conversion of milk into cheese, similar to how curd is formed from milk. These bacteria are present in all the types of cheese and produce lactic acid (a chemical compound) which helps in making a final edible product. Such bacteria bring about chemical changes in the composition of milk.  Depending on the type of cheese, the bacteria added changes.

One such type of cheese is Swiss Cheese, which usually has holes in its structure. Bacterial culture of bacteria Streptococcus thermophilus, Lactobacillus and P. shermani is used in the production of Swiss cheese. These bacteria when mixed with milk at a certain temperature, produce curds. These curds are pressed and soaked in the brine solution (a solution of salt and water). The brine solution is present inside the cheese molds which help in giving the required shape to cheese. The cheese is then stored at 72-80 degree Fahrenheit and left for ripening process.

During the ripening process, these bacteria get the right temperature and start acting on the milk. Lactobacillus and Streptococcus thermophilus release lactic acid which is consumed by bacteria P.shermani. In return, it releases carbon dioxide gas and forms bubbles. These bubbles form air pockets that result in the formation of holes that don’t disappear with time. The size of the holes can be controlled by acidity, temperature and maturing time.
