Oato is a UK-based company specialising in fresh oat milk, produced using 100% British oats. Launched in 2019 by Carl Hopwood, the brand started by offering deliveries via traditional British milk rounds in reusable glass bottles to reduce waste. Their oat milk is non-UHT, meaning it is pasteurised at lower temperatures, preserving more nutrients and offering a creamier taste compared to shelf-stable alternatives. Oato is committed to sustainability, with a solar-powered production facility in Lancashire and a strong focus on reducing single-use packaging.
