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 with Vitamin D, which it naturally lacks, grain milks may have calcium and some vitamins (especially cobalamin) added to them. Cobalamin is produced exclusively by microorganisms: bacteria, fungus and algae, like for example Spirulina. Higher plants and animals are unable to produce it. In lupine milk, cobalamin has been found in larger quantities.
Grain milk is low in saturated fat and contains no lactose, which is beneficial for those who are lactose intolerant. Grain milk also lacks casein, making it suitable for vegans and people with milk allergies.
Flavored grain milk can come in plain, vanilla, chocolate or a variety of other flavors. Like unflavored grain milk, it is often available with added nutrients. There are also grain milk cream and desserts available.
