Depends on the pasteurization method. UHT will change the taste 100%, normal pasteurization might not. My grandmother used to pasterize her milk at a slightly higher than needed temperature, to separate the cream, and eat it on the side. Raw milk/pasterized milk with cream have the same taste, when you remove the cream though, it changes.

Honestly that's the best way to consume milk, pasterize it yourself, that will allow you to control the taste and the fat % you tolerate in your milk.
