It’s a crowded market and the non-dairy cream-of-the-crop right now is oat milk. It’s vegan, gluten-free, nut-free, and GMO-free. Oat milk’s success isn’t just because of all the things it’s not. Oatly, the Swedish oat nerds who launched the drink in the US market, first introduced it to third-wave coffee shops with a special ‘barista blend’ that foams like dairy and works in coffee. Over the past few months Oatly has also been phased into grocery stores and the company’s marketing and oat milk’s tastiness make it a strong bet as the eventual winner of this plant-milk melee.
