Why Drink Kult Kefir Beverages?
A functional alternative to regular lemonades and so-called "probiotic drinks." Craft fermentation – not quick production of carbonated water; the drink mainly contains postbiotics.
- Traditional water kefir – standard fermentation, natural sparkling, gentle pasteurization for stability.
- Postbiotics, not probiotics – no live cultures remain after pasteurization; the drink mainly contains postbiotics produced during fermentation.
- Lower residual sugar – compared to kombucha and most lemonades, there is less sugar.
- Taste without aromas – real juice from organic lemons and organic Peruvian ginger, pure profile.
- Craft production – small batches, organic ingredients, quality control by a fermentation expert.
- Everyday drinking – light, low-calorie, gentle on the stomach.
Looking for a comparison? Kombucha is often more acidic and sweeter. Probiotic lemonade (ang. soda) is more like carbonated water with artificially added cultures.

Water Kefir – Live Fermentation, Gentle Bubbles
Water kefir is made from kefir crystals (tibicos) – a symbiosis of yeasts and bacteria. During fermentation in a sugar solution, organic acids and natural bubbles are produced.
Kult Kefir ferments in small batches from organic ingredients for almost 2 days and uses freshly pressed juices (e.g., in the flavor Passion Fruit and Hops) without artificial aromas.
During fermentation, most of the cane sugar is converted into organic acids, giving the drink a gently tart taste and low residual sugar.
The drink is canned in recyclable aluminum cans (emphasis on efficient recycling and protection from light). The brand was founded by bioengineer Mathilde Riga; the product and recipes are managed internally, but the production itself takes place in Belgium in collaboration with a partner brewery in Antwerp.

What is the Kult Kefir Brand
Kult Kefir brings honest water kefir – a lightly sparkling drink from organic fruits and herbs. Controlled fermentation with traditional mother culture lasts 48 hours. The result is a natural taste, minimal sugar, and a wide spectrum of organic acids.
Behind the brand is a Belgian bioscience engineer. She started at home in the kitchen, today she ferments in Brussels and Wavre. Still in small batches, with an emphasis on quality, transparent composition, and stable flavor profile.
Kult Kefir uses 100% natural ingredients and no artificial additives. Prefers freshly pressed juices and herbal teas.
Thanks to gentle pasteurization, the drink retains postbiotics and is filled into recyclable aluminum cans, which protect the content and save resources.

FAQ
Does the drink contain live cultures?
No. After fermentation, the drink is pasteurized. Live cultures are deactivated. However, postbiotics and natural gentle sparkling remain.

Why do you pasteurize the drink?
For stability and safety without preservatives. Pasteurization stops fermentation and maintains the same flavor profile in each batch.

Do you add probiotics after pasteurization?
No. We do not add "ready-made" probiotics. We rely on naturally occurring postbiotics and pure composition without artificial interventions.

Is KULT really organic?
Yes. We care about organic farming and ingredients in organic quality. This supports biodiversity and pure taste.

Where is KULT produced?
In Belgium, in small batches. The craft fermentation operation prioritizes quality over quantity.

How much sugar does the drink contain?
Most of the sugar is converted into organic acids during fermentation. For the Ginger & Lemon flavor, it's about 2.4 g/100 ml. Check the values on the label.

Is KULT non-alcoholic?
Yes. It contains less than 0.1% alcohol (less than a ripe banana or regular juice).

How is KULT flavored?
We use real ingredients – no artificial aromas or extracts. Whenever possible, we choose freshly pressed juices.

Where does the ginger come from?
From Peru. It has a more pronounced taste and aroma than regular Chinese ginger. The juice is cold-pressed to retain its natural properties.

Are the cans eco-friendly?
Yes. Aluminum is recycled efficiently and repeatedly. It is lightweight, reduces emissions during transport, and protects the content from light and oxygen. The lining is BPA-free.

KULT Kefir is a brand that unites science and the art of fermentation to create naturally sparkling drinks full of probiotics. They are crafted from traditional water kefir grains, without artificial additives, preservatives or refined sugar, with an emphasis on clean ingredients and authentic taste.
It is built on handmade production and a sustainable approach—from carefully selected ingredients to recyclable packaging. It’s a popular choice for those seeking a healthier and functional alternative to conventional soft drinks.

Renowned fermented beverages thanks to:
- 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.
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.
See for yourself.
