Oat drink. Oats are known for their fiber content and various components such as beta-glucans, which are very beneficial for the heart. An alternative to milk. Made with Swedish oats using a patented enzymatic process that retains beta-glucans (4g/L). It is the original oat drink. Only water, oats, and a pinch of sea salt. Oatly developed the world's first oat drink in 1995 and is exclusively dedicated to producing oat-based products.
