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 – live cultures do not remain after pasteurization; the drink mainly contains postbiotics produced during fermentation.
- Lower residual sugar – less sugar compared to kombucha and most lemonades.
- Flavor without aromas – real passion fruit, Sencha tea infusion, and a mild hop line of Simcoe; pure profile.
- Craft production – small batches, organic ingredients, hand 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.

Kult Kefir is a genuinely fermented drink with postbiotics and a pure composition, which is why it costs more and tastes completely different.

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 Yuzu and Tangerine) without artificial aromas.
During fermentation, most of the cane sugar is converted into organic acids, so the drink has a mildly tart taste and low residual sugar.
The drink is bottled 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 led internally, but the actual production takes place in Belgium in collaboration with a partner brewery in Antwerp.
Why choose Kult Kefir
Kult Kefir brings a unique water kefir to the market – a lightly sparkling drink created by fermenting organic fruits and herbs. Thanks to traditional mother culture and 48-hour maturation, it offers a natural taste, minimum sugar, and a wide spectrum 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, he produces kefir 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, supports healthy digestion, and is packaged in fully recyclable aluminum cans that conserve resources.

FAQ
Does the drink contain live cultures?
No. After fermentation, the drink is pasteurized. The live cultures are deactivated. However, postbiotics and a naturally gentle effervescence remain.
Why do you pasteurize the drink?
For stability and safety without preservatives. Pasteurization stops fermentation and keeps the same flavor profile in every batch.
Do you add probiotics after pasteurization?
No. We don’t add “ready-made” probiotics. We rely on naturally occurring postbiotics and clean ingredients without artificial interference.
Is KULT truly organic?
Yes. We prioritize organic farming and organic-quality ingredients. That supports biodiversity and a clean taste.
Where is KULT made?
In Belgium, in small batches. The craft fermentation operation favors quality over quantity.
How much sugar does the drink contain?
Most of the sugar is converted during fermentation into organic acids. For the Hops & Passionflower flavor it’s about 2.4 g/100 ml. Check the exact values on the label.
Where do the ingredients come from?
KULT Kefir uses organic ingredients – fresh fruit and herbs from certified organic farming. The brand prefers freshly pressed (cold-pressed) juices and works without artificial flavorings and extracts.

How is KULT flavored?
We use real ingredients—no artificial flavors or extracts. Whenever possible, we choose fresh, cold-pressed juices.

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.
