The liquid in cheddar cheese is called whey. During the cheesemaking process, milk is separated into solid curds and liquid whey. The curds are then pressed and aged to become cheddar cheese. Whey, rich in proteins and lactose, is often drained off but can be used in other food products or as an animal feed.
