Oatly Oatmilk is an oat-based milk challenger made for people who want to replace dairy from a cow in their everyday life. Since the last millennia, Oatly has been committed to finding new ways to make it easy for people to eat better and live healthier lives without recklessly taxing the planet’s resources. What started with the first oatmilk has become specialty coffee products, replacements for cooking creams, whipped cream, spreads, and even soft serve. Our oat base is just oats and water. But it’s what we do with those oats and that water that makes Oatly so special. In most oatmilks, we add the vitamins and minerals, and source of fat you might need when shifting from an animal-based diet to a vegan or more plant-based one.
