ELI5: How are different types of cheese made? What creates the difference between swiss and cheddar?
gpt
Swiss cheese is inoculated with a culture that chows down on the cheese as it cures and it gives off little bits of gas as it does so. This sharpens the cheese and develops flavor, complexity, and bubbles which give swiss cheese it's famous holes. 

Cheddar cheese is made by a process called cheddaring where the still wet curds are separated from their whey by the cheese maker. Curds are very soft like cottage cheese and very watery. So they scoop the curds to the side and let them dry. They heavily salt the curds and then turn them several times helping them dry even more. When dry enough they will pack them into wheel shaped molds wrapped in cheese cloth and stack them one on top of the other so the weight helps squeeze even more water out. They continue flipping or cheddaring the wheels until most of the moisture has been removed and you end up with a solid block of newly pressed cheese. It has none of the flavor it will as it ages so off to the aging racks it goes where the salt, enzymes left over from the cheese making process continue to break down and re-arrange bits of the milk proteins forming new sharper flavors and a more developed taste. The longer it's aged the better the flavor.
