TKSST posted this video of a farmer making cheese in a big vat.

To give you a sense of what’s going on, these are the steps shown.

A farmer milked the cows, and a tanker from the dairy came to collect the milk.

1. In the dairy, cheese makers warmed up the milk…

2. …and added bacteria to make it turn sour and thick.

3. Then they added a substance that animals use to digest milk called rennet…

4. …and it changed again into bits called curds, floating in whey.

5. They drained off the whey, chopped up the rubbery curds, added some salt, and pressed them into blocks.

6. They stored the blocks for months until the cheese was ripe.

And depending on the cheese, it could take anywhere from a few weeks to several months for the entire thing to be done.
