This is the original Oatmilk in a single serve ambient package so you can store it at room temp or merchandise it in your refrigerated shelves. We just love this product. Its made fresh from 100% gluten-free oats and enriched with calcium. It has amazing beta-glucans (big, scientific word for soluble fiber from oats), and is naturally low in saturated fat. When should you use it? Whenever you would use old school milk from cowschilled straight from the container, for cooking or bakinguse this little oatmilk instead.
