Slow. Transparent. We show who grew it, how we made it, and how long it took — then let the flavour do the rest.
Leave your email and we'll let you know when we're ready. No spam — just a note when there's something to taste.
Products
Whether it starts with a koji culture, herbal infusion or simply salt, fermentation takes however long it takes. Weeks for a kraut, months for miso, over a year for shoyu. We show you what's in it, where it comes from, and how long it took.
Raw honey, green tea, live culture. Lightly effervescent, floral, gently tart. 4–6 weeks fermentation.
Fava beans and buckwheat, salt, time. Pressed after 18 months of slow fermentation. Deep and savoury.
European vegetables, traditional method. Savoy cabbage, radish, gochugaru, garlic, ginger. Naturally fermented.
Process
Every product follows a different path — koji for miso and shoyu, wild brine for lacto-ferments, a living culture for kombucha. What they share: careful sourcing, a controlled environment, and enough time. Nothing is accelerated; nothing is rushed.
01
Grains, beans, and vegetables from passionate producers. Where the ingredient comes from matters.
02
Each fermentation style starts with the right culture — seeded, maintained, and understood.
03
Packed into vessels and left alone. Checked, tasted, adjusted where needed. The colour deepens, the flavour builds — on its own schedule.
04
Unpasteurised, live cultures intact. Packed with the batch number, fermentation time, and ingredients on every label.
About
Oku started from curiosity — about koji, about fermentation, about what happens when you give good ingredients enough time. Everything is made in small batches, by hand, with full transparency about what goes in and how long it takes.
Every ingredient is traceable. We name the farm, name the grower, and tell you what they grow and how. Their story is part of the product.
Fermentation time, batch number, method — it's all on the label. The process is open because there's nothing to hide.
No shortcuts, no accelerants. Good fermentation takes the time it takes. We let the flavour develop on its own schedule.
