our story
"Our aim is to bring Portuguese consumers
living foods of greater nutritional and sensory quality"
Founder of Kin Ferments
01 Who We Are

We began from a conviction: that Portugal has the ingredients, the climate and the tradition to make ferments of world standard.

We work at nature's pace, in small artisanal batches, with an unwavering focus on quality. We partner with small organic growers and build upcycling into our process to cut food waste.

Every product begins with a conversation with a farmer. Nothing goes into a Kin jar without being tasted first — and every batch undergoes rigorous microbiological analysis before it leaves our hands.

from the heart of Portugal
02 Why Fermented

A fungus that grows on plant bases and raises their nutritional value for the person eating them.

Nutrition

Koji uses grains and pulses as its energy source, releasing enzymes that raise nutritional bioavailability. More amino acids, more B vitamins, more life on the plate.

Flavour

Umami isn't added — it's cultivated. Koji fermentation builds a depth of flavour no additive can replicate. It's the difference between a good dish and one you don't forget.

Sustainability

We shorten supply chains, make use of agricultural surplus and build upcycling into how we work. Fermenting is also an intelligent answer to food waste.

03 How We Make It

From grain to jar: no shortcuts, no compromises.

Selection
Organic grains and pulses from small Portuguese growers. Quality begins in the field, not in the laboratory.
Inoculation
The koji (Aspergillus oryzae) grows for 40–48 hours under controlled temperature and humidity. A process that demands constant attention, day and night.
Fermentation
Days, months or more than a year in Portuguese oak barrels. Each product has its own pace — time is the only accelerant we use.
Validation
Rigorous microbiological analysis before packing. Every batch identified and traceable from field to jar.
