A Michelin chef doesn't cut corners. Neither does your oat milk.
KOATJI is the organic barista oat & koji milk chef Rasmus built to his own kitchen standard — clean ingredients, no added sugar, and excellent taste and performance in your coffee and matcha.
“I would never put a bad oil in something with my name on it.”
Rasmus, Michelin chef & co-founder of KOATJI
The guiding principle
My philosophy as a chef is to start with the best and purest ingredients.
When I sourced our ingredients, I insisted on the highest quality and we follow the whole journey — from farm to table.
That's how I cook. You can taste when something's done right.
So we chose the same oil I would use at home
- Organic
- ~75% monounsaturated — the olive-oil kind of fat (extra virgin olive oil only needs ~55% to qualify)
- High in omega-9 — the same oleic acid that makes olive oil famous
- Low in Omega-6
- Naturally containing vitamin E
Why we add sunflower oil
A barista plant milk needs fat. It creates the creamy mouthfeel, rich flavor, and silky micro foam that make great coffee possible.
That's why we use a small amount of organic high-oleic sunflower oil, chosen for its performance, not as a filler.
Clean all the way through
The oil is just where the standard starts. Every ingredient earns its place.
- No added sugar, no refined sugar — only the natural glucose from the oats
- Naturally rich in B vitamins from koji fermentation
- No gums. No emulsifiers. No fillers.
Built for your coffee and your matcha
Clean doesn't mean compromise. KOATJI was engineered in a chef's kitchen to taste and perform — silky steamed microfoam, latte art that holds, and no splitting against hot espresso or whisked matcha. Excellent taste, every cup.
- Froths and steams like a dream — barista-ready microfoam
- Holds in coffee and matcha — no curdling, no separating
- Creamy from koji, not from gums — body that comes from fermentation, not fillers
Microfoam perfection. Every pour.
Don't take the chef's word
We handed the verdict to an app we don't control. KOATJI rates Excellent on Yuka — the independent ingredient scanner used by millions, where no brand can pay its way in.
We didn't invent oat milk. We kind of perfected it.
Creamy enough to froth like a dream. Clean enough to read the whole label out loud. Built to the standard of a chef who has his name on it.

Questions? We’ve got answers!
Wait isn't sunflower oil a seed oil?
Yes! Seed oils are a nuanced topic, and we take it seriously. Every ingredient in KOATJI is intentionally chosen based on flavor, performance, and science — not trends. Our organic high-oleic sunflower oil contains 75% monounsaturated fat, making it naturally low in omega-6 and rich in oleic acid (omega-9) — the same well-regarded monounsaturated fat found in olive oil. Clean, stable, and with natural vitamin E. That’s why KOATJI rates excellently in the health category on the YUKA app.
Will it work in my morning coffee and matcha?
That's exactly what it was made for. KOATJI creates silky microfoam for espresso while its subtle umami complements ceremonial matcha instead of overpowering it. One oat milk, both rituals.
Why koji?
Koji is the ingredient behind foods like miso, soy sauce, and sake. It's been used in Japanese kitchens for over a thousand years. In KOATJI, koji naturally creates depth, creaminess, and a clean finish - without gums or unnecessary additives.
Is there added sugar?
No. We do not add any sugar to KOATJI.
During our natural fermentation process, enzymes break down the starches in organic oats and koji rice into naturally occurring sugars (maltose and glucose). Current FDA regulations require these naturally created sugars to be labeled as "Added Sugars" on the Nutrition Facts panel, even though no sugar or sweeteners are added as ingredients.
