Fermenting sounds like a laboratory technique, and it is actually one of the oldest things done in a kitchen. Bread, wine, sauerkraut, cheese: they all exist because someone let a few microorganisms work at their own pace. With coconut it is exactly the same.
Fermenting is letting cultures do the work
You start with a base —in our case, coconut— and add cultures: selected lactic acid bacteria. From there you don't do much. You hold the temperature, you wait and you let them work.
There's no stirring, no heating, no correcting. Fermenting is, above all, not intervening.
From sugar to acid
Lactic acid bacteria feed on the sugars already present in the raw material and turn them, mainly, into lactic acid. That's the whole mechanism, and it explains almost everything that follows.
As acid is produced, the pH of the mixture drops. The lower it goes, the more tangy it tastes. That tangy note at the end —the one that appears just after the sweetness of the coconut— isn't added: it forms.
That same acidity is the reason fermenting has been a way of preserving the harvest for centuries. Before fridges existed, that was the fridge.
Why the texture changes
As the pH drops, the structure of the mixture changes and the whole thing thickens. In milk, that change is led by casein. In a plant base there is no casein, so the texture depends on other things: the coconut's own fat, the recipe and the time it's given.
That's why two plant-based ferments can turn out very differently from the same ingredient. The thickness isn't an additive: it's a consequence.
Time can't be rushed
You can ferment warmer to go faster, but the result isn't the same. The aromas that form slowly don't form quickly. A short fermentation gives you something tangy; a slow, calm fermentation gives you something tangy and with depth.
We ferment slowly, in Spain and in small batches. It isn't a secret technique. It's basically waiting.
And no, it isn't a dairy ferment
The confusion is understandable: it looks similar on the spoon and is used in similar ways. But a dairy ferment, by definition, is made with milk. Ours is made with coconut. They share the method —fermenting— and don't share the ingredient.
And that distinction isn't just about the label: it changes what it tastes like, it changes the texture and it changes how it behaves in the kitchen.
If you want to see it on the spoon, the 500 g size is the thickest and the kefir style the runniest. And to start using it, take a look at our recipes.
