For our Oat Original, we use natural enzymes to cut whole grain oats. During this process, the natural carbohydrates are “cut” into smaller chain carbohydrates which is actually sugar. Long story short, we don’t add any sugar into our Oat M*lk but some natural sugar results from our processing. For our Oat Zero Sugar, we use oat flour instead of whole grain oats, which means no hefty work to break down the oats and no sugar is created in the process.
