A milk substitute made from fermented grain or from flour. Grain milk can be made from oats, spelt, rice, rye, einkorn wheat or quinoa. Grain milk looks very similar to cow's milk. It has a lower protein content and a higher carbohydrate content than cow's milk. Just as cow's milk is often fortified, grain milks may have calcium and some vitamins (especially B12) added to them. Grain milk is low in saturated fat and contains no lactose, which is beneficial for those who are lactose intolerant.
