A local small grocery chain started stocking raw milk (with many warnings) and I decided to risk consuming it to see for myself. I couldn't tell the difference between it and ordinary full fat milk. I wondered if it was a fraud (commercial milk falsely advertised as Local Forbidden Delicacy Milk), but maybe there's not much difference. Or maybe I am not a subtle taster. I also can't taste the superiority of an $80 bottle of wine when it's pitted against an $18 bottle.
I can taste the difference between a $100 wine and $400 wine, but it's maybe 20% better, if it's possible to flatten extra layers of flavour into a linear scale. It's easier to appreciate for different levels of quality from the same producer. My example is drawn from Casanova di Neri Tenuta Nuova vs Cerretalto. They're basically the same style, the Cerretalto just has extra.
Across different grapes and regions and it's like apples and oranges. Sometimes I want a savory Burgundy, sometimes I want a Coke. If you don't know what wine from a terroir tastes like, and hankering after that, don't spend extra on it.
I'd generalize that to cheese. Can't beat a good aged Comte (a raw milk cheese), but it's not everyday cheese.
I’ve had a few different specialty brands of milk and there can be a difference, but I think that has more to do with the cows (and their diet) than the process. Jersey cow milk is probably more different than raw milk than pasteurized is from raw milk.
