Ever wondered why there are those magestic holes in Swiss cheese? Although mice have been known to fall victim to deadly traps due to their horrible addiction to cheese they do not create the holes in this one, contrary to popular belief. First of all, the real name for the cheese in discussion is Emmentaler (Emmental). Propionibacter Shermani is one of the three types of bacteria used to make said cheese, and it's responsible for the cheese's iconic holes. Once the bacteria is added to the cheese mixture and warmed, bubbles of carbon dioxide form. These bubbles become holes in the final product.

Knowledge is power.
