Finally, an oat milk that actually tastes good! That’s exactly what we thought when we tried ROA Barista for the first time. From now on, you can find the oat milk from this Amsterdam startup both in our roastery and here in our online shop. ROA Barista Oat Milk is a balanced, creamy oat milk that immediately won us over with its flavor. It foams beautifully and is the perfect addition to your cortado, flat white or cappuccino. Made with no added sugar — just the natural sweetness from whole European oats.
