Ever wonder why are there holes in Swiss cheese? It is because of the “bacteria” used in making the cheese. These bacteria form holes on the dairy during the aging process. As the cheese ages and solidifies, the bacteria added continue to eat it away forming pockets on the cheese.

One kind of bacteria, the P. Shermani consumes the lactic acid excreted by other bacteria, in this process; carbon dioxide and propionic acid are given off from which the bubbles are formed. And, when a bubble bursts, it leaves a hole in the cheese.
