Imagine going into a store and being in a hurry to buy milk and finding out it's oat milk at home and not the almond milk you wanted if everything is labeled "Malk"......Any nut or grain milk is already labeled as to what it is in big bold letters because there are different kinds. Redundant labeling is stupid at that point.

And while I've not had yak milk, I have had sheep and goat milks, they are fine to drink. And while I'm all for pasteurized milk for food safety reasons, I grew up on a dirt poor dairy farm. And we drank raw milk every day because we had free fresh milk all the time. I can tell you that it smells and tastes nothing like the pasteurized 1% or 2% milk that gets sold in the grocery store. I guarantee you would turn your nose up and run away.
