The Randomness of Cheese

I like that cheese sometimes has holes and sometimes does not have holes, it's totally random. I might choose a delicious Swiss cheese sandwich and the cheese might have holes, alternatively, if I were to make that same Swiss cheese sandwich with Gruyère and maybe leave out the Swiss, it might not have holes, who knows. Because you see, holes in cheese is decided by the fates and not by some cheese making process whereby the cheese-maker adds Propionibacter Shermani that produces carbon dioxide which forms whole bubbles in the cheese, that when cut into thin slices manifest as holes in the slices of cheese.
