Discover our natural assortment
Your gut deserves real food. That’s why at Klejman Fermentista we ferment fresh, raw vegetables, fruits, and herbs, without additives and without pasteurization. Crafted by hand, in small batches, for a thriving microbiome.
Not pasteurized
Our fermented products are not pasteurized. This keeps the lactic acid bacteria alive and provides a natural source of probiotics.
Without additives
We do not add sugars, preservatives, flavor enhancers or dyes.
Made in Belgium
All our products are made with love in Belgium. In our cosy workshop in Wilsele we devise and prepare the fermented delicacies.
Natural probiotics
Our fermented products contain, in addition to fresh raw vegetables, fruits, and herbs, above all a lot of love. Everything is prepared artisanally (yes – we cut, knead, mix, and prepare everything ourselves) according to the principles of traditional fermentation. We use no added sugars, preservatives, flavor enhancers, or colorants. Our products are not pasteurized in order to keep the lactic acid bacteria alive, making them a natural source of probiotics.
Fermentista - the healthy power of fermented vegetables
Two sisters, one mission, and now ... a book.
When we moved from Poland to Belgium 25 years ago, we unknowingly left behind an important part of our health: fermented food. Years later, we found our energy and balance again, thanks to one simple spoonful a day from a jar ... fermented vegetables.
Now we want to bring that jar to your fridge, but this time not just through our products or workshops. No, this time it will be a book.
The power of fermentation
Fermented vegetables are your secret weapon for a healthy life. A healthy life starts with healthy nutrition, and fermented vegetables are your ultimate ally. They are key to a balanced gut microbiome and offer a wealth of fiber and probiotics to keep your digestive system working at full capacity. Plus, they can help support your natural defenses.

Marta Klejman has been elected Strongest Female Entrepreneur of Flemish Brabant 2026.
What a moment. Thanks to your votes and support, we were able to win this title. It feels like a huge recognition of what we build every day at Klejman Fermentista: craftsmanship, flavor, and real, live fermented vegetables that help people take better care of their gut and health.
Deze prijs is niet alleen voor Marta en Joanna een bekroning, maar vooral extra zichtbaarheid voor gefermenteerde voeding in Vlaanderen. Hoe meer mensen ervan proeven, hoe sneller het een vaste plek krijgt in de koelkast, naast alles wat er al staat. Dankjewel om mee te dragen aan dit verhaal!
