Oat milk tastes like oats. Which is good if you want to taste oats, and bad if you want to taste anything else.

It's pretty good. Creamy, not too grainy or anything, tastes pretty good with the vanilla and doesn't use nearly the amount of water crop wise.

But also I can cook with it.
But I do look forward to if that yeast milk ever makes it to market.

Soy milk is great, but it's not a good milk substitute.

It should taste beany, and that's not really what I want with my cereal. A Chinese cruller, on the other hand...

Another one I like is coconut + rice. It's more like a milky drink than milk, but it's tasty.
