Oatmilk is the superior alternative milk, assuming you get the pricier brands. Excellent for coffee.
Rawmilk made my wife have the runs when in France. YMMV.
It doesn't taste anything like regular milk. It's much richer and fuller in flavor. I am not a big milk drinker myself, until I was introduced to raw milk. I was taught to be afraid of it, but it is fairly safe, I don't let my kids drink it, though it would probably be fine if I did...
Does it taste any different than regular milk?
I've never been a big fan of plain milk. Just think it tastes weird. Though I'll have flavored milk such as chocolate, and I enjoy some of the nut milks sometimes.
