Our Product

Oat Drink Production

THE OATER machine produces fresh, barista-quality oat drink at the push of a button. Simply add our ingredient mix and let our machine do it’s magic. The machine uses a low-temperature fermentation process to make our oat drink naturally sweet and creamy.


At The Oater we value quality, sustainability and timeless design. For that reason our machine is entirely designed, developed and manufactured in Germany with high quality materials. We believe sustainable hardware can be elegant and timeless.


We keep things simple and haptic to serve our users in their fast-paced work flows. 3 buttons, minimal display design to indicate status, no manual cleaning. This lets The Oater fit seamlessly into any process and add value not only to the oat drink consumer but also to the user interacting with our machine.


For Businesses

Our creamy Barista Oat Milk and our innovative machine with timeless design not only provide a harmonious taste experience and superb foam stability, but also offer you a more sustainable milk and a unique selling point. You do NOT have to buy our machine, you rent it and only pay a flat rate per liter for our ingredient mix. If you have any questions, please contact us at

The OATeam

We are a team of dreamers and oat drink enthusiasts from Cologne, who firmly believe that there is still room for improvement in oat drink. It all started when our CEO Sarah, who has been vegan for 7 years, was bothered by all the packaging waste and the lack of freshness of her oat drink. There has to be a better way, she thought to herself. And now over 1 year later, we can say with conviction: Yes, it can be better! Our oat drink is fresher, more regional, cheaper, more delicious AND more sustainable than other solutions in the market today. We are Sarah, Henrik, Lisa and BenjaminJoin our oat drink revolution!

…you reduce C02 emissions.

Our ingredient packs weigh only 1/10 of a packaged oat drink. And less weight and organic oats from Germany means less transport emissions.

…you save 90% packaging waste.

Our oat drink comes without any disposable packaging at all, saving up to 90% packaging waste. We are currently developing a reusable packaging system for our ingredient mix.

…you stay climate-neutral

It’s important to us to produce as few emissions as possible in our entire value chain and we optimize continuously. The unavoidable emissions are compensated.
