How Cheese is Made

How cheese is made

Have you ever wondered how cheese is made? How a vat of liquid milk is transformed into buttery brick, creamy colby, marvelous mascarpone, or salty ricotta salata? Or how so many different cheeses can be made with just four ingredients – milk, salt, rennet, and cultures?

The cheesemaking process is surprisingly simple. Milk is treated with bacteria and rennet to curdle it. The curd is then cooked, salted, cut, pressed, brined, pulled, washed, stacked, or skewered with needles to create more than 1,800 different kinds of cheeses.

The cheesemaking process

Cheese starts as milk from cows, sheep, goats, or even buffalo, to which cheesemakers add a starter culture and rennet. The bacteria in the starter culture acidifies the milk, turning lactose into lactic acid which helps to give the cheese its flavor. And the rennet enzymes in cheese curdle the milk, separating it into solid curds and watery whey.

What happens next determines what kind of cheese the milk will become. To create certain soft cheeses, cheesemakers simply drain the curd, salt it, and package it. To make harder cheeses, the curd may be cut into small pieces and heated to force more moisture from the curd. Sometimes the curd is stretched and kneaded in hot water to create cheeses like mozzarella and provolone. It may be cut into blocks and repeatedly stacked and flipped to create cheddar cheese. It may be washed in warm water repeatedly to create cheeses like gouda and colby. Or it may be spiked with needles to allow bacteria within the curd to grow and form a blue cheese.

Eventually, most cheeses are pressed into a cheese mold and left to age for a few days to several years or more. The longer the cheese ages, the sharper and more complex its flavors will be.
