cheese has a different process for making it each time. The first division is pasteurised/unpasteurised. This is whether or not you 'cook' the milk at 62 degrees centigrade first to rid it of any bacteria such as listeria (though evidence that milk has listeria in it in the first place is very far and few between). This changes the consistency of the cheese on a small scale. An uncooked cheese will be a lot 'smoother' and curdy. You get much more of a creamy taste with unpasteurised.
