I'd like to try Oatly, but it is not sold here. I tried making oat milk myself, but it turned out terrible. I actually quite like the idea of vegetable milk and have tried making a bunch myself: soy, oat, rice, coconut and peanut. Of those the best ones are coconut and peanut. Unfortunately cocunut has a strong characterist flavour, so it doesn't work everywhere, but peanut milk is really very good, and has no noticeable taste, it's good even to drink plain, I recommend you try.
