It does taste different.l but it’s still milk.
I’ve grown up on a farm, and milk can even taste different from cow to cow, or at different times of the year if that changes their alimentation.
Raw milk also usually has a higher fat content than what most people buy.
Ours would average 4.5%.

Different breeds also taste different, holsteins, ayrshires, jerseys, etc.

I’ve never been a big fan of milk, so I can’t into much details on flavor.

I personally wouldn’t procure raw milk from a farm I didn’t know very well.
