Water Kefir Full of Ready Postbiotics
Kult Kefir is a gently sparkling water kefir, which through 48-hour fermentation and traditional mother cultures naturally transforms organic sugar into organic acids and enzymes.
In the Raspberry & Mint – sugar-free variant, fermentation is carried out so that the resulting drink contains 0 g of sugar per 100 ml.
These organic acids are among postbiotics – substances formed during fermentation.
They give the drink a pleasantly tangy taste without the need for artificial flavours. Kult Kefir is made from organic ingredients, in small batches, and filled into lightweight, fully recyclable cans.
Why Choose Kult Kefir
Kult Kefir brings a unique water kefir to the market – a lightly sparkling drink created by fermenting organic fruit and herbs. Thanks to traditional mother culture and 48-hour maturation, it offers a natural taste, minimal sugar, and a wide range of organic acids – a perfect alternative to sweetened lemonades.
Behind the brand is a Belgian bioscience engineer who started fermenting at home in the kitchen; today, kefir is produced in Brussels and Wavre, still in small batches to maintain the freshness and authentic aroma of each batch.
Kult Kefir relies on 100% natural ingredients, without artificial additives, and uses freshly pressed juices or herbal teas. The drink is rich in postbiotics and is packaged in fully recyclable aluminium cans, conserving resources.

FAQ
How does the "Zero" version taste compared to classic water kefirs?
The taste is cleaner and drier. As it contains no residual sugar or substitute sweeteners, the natural acidity of fermentation and the freshness of mint stand out. It's the ideal drink for those who prefer "lemonades" without a sticky mouthfeel.
Does this drink contain any alcohol?
Kult Kefir is classified as non-alcoholic. It contains less than 0.1% alcohol, which is a trace amount common even in fruit juices or very ripe fruit. It is therefore completely safe for drivers and abstainers.
Is pasteurisation a barrier to substances produced by fermentation?
No. Pasteurisation stops active fermentation so that the can doesn't "work", but postbiotics, organic acids, peptides, and enzymes remain part of the drink. This keeps the taste stable in every batch.
Is the drink suitable for Low-carb diets?
Yes. With zero sugar content, it is suitable for those watching their carbohydrate intake. Always follow your own diet and the nutritional values on the label.
Can kids drink this beverage?
Yes. Kult Kefir Zero is a non-alcoholic, pasteurised drink without sugar and sweeteners. For younger kids, it's advisable to start with a smaller amount, as with other fermented drinks.
Do I need to store the drink in the fridge immediately after delivery?
Thanks to pasteurisation, the drink is storable at room temperature. This is a practical advantage over live kefirs. We recommend chilling the can for a few hours before opening for maximum refreshment.
What is the difference between probiotics and postbiotics in this drink?
Probiotics are live bacteria, while postbiotics are substances produced during fermentation. After pasteurisation, the drink no longer contains live cultures, but it retains the fermented profile and substances produced during fermentation.
Does the drink contain gluten or soy?
No. Kult Kefir is naturally gluten-free, soy-free, and lactose-free. It is based purely on water and plant-based organic ingredients, making it suitable for vegans.
Why do you use aluminium cans instead of glass?
Aluminium is well recyclable and lightweight for transport. The can also protects the drink from light, which can affect the taste and quality of the content.
Is the added vanilla for sweetness?
We use natural vanilla flavour for flavour rounding of the drink. Vanilla softens the acidity and helps create a fuller taste without added sugar or sweeteners.

- Clean formulation — made from water kefir with no artificial additives, no preservatives and minimal processing; each batch delivers naturally occurring postbiotics as the result of authentic fermentation.
- Carefully selected ingredients — every kefir grain arises from natural processes through which values and culture are passed down from generation to generation; the recipe reflects the authenticity and quality of fermentation.
- A fusion of tradition and innovation — unique recipes draw on kefir-grain cultures handed down through generations while leveraging modern insights from the biosciences to achieve exceptional flavour and function.
Water kefirs
Who’s behind the Kult Kefir brand
The driving force behind Kult Kefir is Mathilde Riga, a passionate Belgian bioengineer who turned her love of the biological sciences into a delicious fermented drink. Her journey began in her own kitchen, where her mother passed on water kefir grains—and from that moment a vision was born. Blending home experiments with scientific expertise, she created a brand that pushes the boundaries of traditional fermentation.
During her experiments, Mathilde realised that everyday ingredients hold remarkable potential — and in October 2020 she “planted the seeds” of KULT. Since then, she has shaped a brand philosophy grounded in innovation, authenticity and the simple purity of ingredients. KULT emerges as a union of science and art, poured into every bottle that tells a story of passion, quality and nature’s wonder.
The Kult Kefir vision
The vision of Kult Kefir is to push the boundaries of taste and wellbeing and to craft uncompromising fermented drinks, where every sip tells a story of passion, innovation and nature’s wonders.
The brand invites you on a journey through fermentation—to experience KULT and discover something extraordinary in every sip.
It fulfils this vision by combining the biological sciences with the art of fermentation, emphasising authentic processes and honouring the mother culture and the cyclical passing on of kefir grains—from generation to generation.
In this way, Kult blends tradition and innovation into drinks that honour their natural origin and quality craftsmanship.
The name — how it came about and what it stands for
The word “culture” has its root in the Indo-European kwel, denoting a cyclical process.
The name KULT was chosen as a tribute to the unique relationship between water kefir and the idea of culture. Just as cultural heritage is passed from generation to generation, water kefir grains are handed on in an endless cycle.
It also points to the mother culture—the beneficial microorganisms that trigger the fermentation of every new batch.
What is a fermented lemonade?
A fermented lemonade is a naturally sparkling drink created when a culture (for example, water kefir grains) converts part of the sugar from water and fruit during fermentation into organic acids and gentle bubbles of carbon dioxide. The result is a refreshing beverage with lower residual sugar and a complex flavour—entirely different from ordinary sweetened sodas.
According to KULT Kefir, “water kefir is more than just lemonade”: it’s a traditional fermented drink made from fresh fruit and natural botanicals. The brand uses only real ingredients (with no artificial flavours or extracts), favours fresh, cold-pressed juices and ferments the kefir for almost two days to achieve an authentic flavour profile—a natural alternative to conventional sodas.
Fair production and wholesome lemonades
Production and ingredients
KULT lemonades are made in Belgium through artisanal production and in small batches—literally in a microbrewery in Brabant, enabling careful quality control and consistent flavour.
The brand adheres to an organic standard under the supervision of BE-BIO-01 (CERTISYS), the official Belgian organic certification recognised across the EU.
Thanks to its local, small-scale approach, KULT is an honest, authentic drink with a focus on ingredient origin and fair processing.
Flavouring relies on real ingredients—no artificial flavours or extracts. Kult works with a variety of herbs, prioritises fresh, cold-pressed juices and allows the kefir to ferment for almost two days to achieve an authentic flavour profile.
In practice this means recipes like ginger & lemon with a share of ginger and lemon juice, as well as no-sugar variants where a longer fermentation consumes all the sugar—with no sweeteners and no shortcuts.
Is the packaging eco-friendly?
Yes. KULT chooses aluminium cans as a deliberately eco-friendly pack: aluminium can be recycled repeatedly without loss of quality, it’s lightweight and stackable (lower transport emissions) and it also protects the drink better from light and oxygen; the interior has a BPA-free liner.
The brand also asks for proper sorting: cans go into the “blue” bin (metals) and—where glass is used—bottles go into the glass container without the cap. KULT explicitly notes that cans are better for the planet than single-use glass.
Kult Kefir brings you pure taste, gentle refreshment, and naturally occurring postbiotics from authentic fermentation — with no artificial flavours and less sugar than ordinary lemonades.
