Water Kefir Hops & Passionfruit – Kult Kefir
Looking for a healthy alternative to alcohol or overly sweet drinks? Kult Kefir offers a refreshing, sweet-sour taste reminiscent of a premium lemonade, but with significant health benefits. The drink is lightly sparkling, with an exotic aroma of passionfruit and a refined bitterness from Simcoe hops. Best enjoyed ice-cold.
The drink naturally ferments thanks to kefir crystals (a symbiosis of yeast and bacteria). The process typically takes 36–48 hours, during which microorganisms consume most of the sugar.
The final drink is pasteurised, ensuring flavour stability and safe consumption. It mainly contains postbiotics – valuable substances produced by fermentation, which are resistant to temperatures and ready for your body.
Made in Belgium in small batches. Organic, vegan, gluten-free. Ideal for Low Carb, Keto, and Paleo lifestyles. Discover other Kult Kefir flavours.

Why Choose Kult Kefir Drinks?
A functional alternative to regular lemonades and so-called "probiotic drinks". Artisan fermentation – not quick production of carbonated water; the drink mainly contains postbiotics.
- Taste without Compromise – A sweet-sour profile that doesn't have a "vinegary" aftertaste. Tastes like a genuine artisan non-alcoholic drink.
- Postbiotics for Stability – Thanks to pasteurisation, the drink doesn't ferment in the bottle. Postbiotics support gut integrity without the need for live cultures.
- Non-Alcoholic Refreshment – Alcohol content is less than 0.1%. Safe for drivers, athletes, and as a "party drink" without a hangover.
- Low Carb & Keto Friendly – Minimal residual sugar (only 2.4 g per 100 ml) doesn't disrupt ketosis or insulin levels.
- Clean Label – Real passionfruit, green tea infusion, and hops. No flavours, colourings, or preservatives.
- Suitable for Everyone – Safe for kids, pregnant, and breastfeeding women due to pasteurisation and organic quality ingredients.
Looking for a comparison? Kombucha is often more sour and sweeter. Probiotic lemonade (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 yeast 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 nearly 2 days and uses freshly pressed juices (e.g., in the Yuzu and Mandarin flavour) without artificial flavours.
During fermentation, most of the cane sugar is converted into organic acids, giving the drink a mildly sour taste and low residual sugar.
The drink is canned in recyclable aluminium cans (emphasising efficient recycling and protection from light). The brand was founded by bioengineer Mathilde Riga; the product and recipes are managed internally, but production takes place in Belgium in collaboration with a partner brewery in Antwerp.
Why Choose Kult Kefir
Kult Kefir introduces a unique water kefir to the market – a lightly sparkling drink created through the fermentation of organic fruits 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, supports healthy digestion, and is packaged in fully recyclable aluminium cans, conserving resources.

Composition analysis and functional benefits
Filtered water
Foundation of purity: Water free from chlorine and impurities is key for the growth of kefir culture and a clean taste profile without any aftertaste.
Water kefir culture
Engine of fermentation: A unique symbiosis of bacteria and yeasts that transforms sugar into bioactive substances beneficial for the body within 48 hours.
Organic cane sugar
Fuel for life: Not for sweetening you, but as energy for the bacteria. Only the necessary minimum remains after fermentation.
Lemon concentrate

Passion fruit juice (2 %)
Exotic antioxidant: Cold-pressed passion fruit adds tropical aroma and polyphenols protecting cells from stress.
Green tea infusion
Source of catechins: Sencha green tea provides a gentle herbal depth and supports normal metabolic function.
Simcoe hops (0.05 %)
Aromatic finish: Legendary hops impart resinous notes. They have a calming effect on digestion and balance the sweetness of passion fruit.
What does it mean for you?
Kult Kefir with hops and passion fruit is a sophisticated non-alcoholic drink for adults and kids. It offers a complex experience – from the first fruity note through gentle bubbles to hop bitterness. Thanks to pasteurisation, you can be sure the drink always tastes great and benefits your body through postbiotics, without worrying about sensitivity to live yeasts.
Warnings and storage
- Low sugar: Most sugar has been transformed into healthy acids through natural fermentation.

- Open carefully: Natural effervescence may create slight pressure under the lid.
FAQ
How does Kult water kefir taste compared to regular soda?
It tastes like a light craft soda. It's sparkling and sweet-sour but lacks the "sticky" sweetness of regular sodas. Simcoe hops give it an adult character similar to non-alcoholic beer, while passion fruit maintains an exotic line.
Does the drink actually contain any alcohol?
Legally, it is a non-alcoholic drink. It contains less than 0.1 % alcohol. For comparison – even regular toast bread or ripe bananas can contain more residual alcohol than Kult Kefir.
Is it suitable for a Low Carb or Keto diet?
Yes. With 2.4 g of sugar per 100 ml, it is among low-carbohydrate drinks. It's an ideal "treat" for those who no longer want to drink just plain water but want to stay in ketosis.
Why do you pasteurise the drink? Don't you lose the benefits?
Pasteurisation ensures safety and stability. While live cultures are deactivated, postbiotics remain in the drink – bioactive molecules (enzymes, organic acids) that are extremely beneficial and stable for the body.
Can kids and pregnant women drink Kult Kefir?
Yes. Thanks to pasteurisation, there is no risk of contamination by wild yeasts, and the low sugar content along with zero alcohol makes it a safe choice for the whole family.
Does the drink need to be constantly refrigerated?
Unlike "live" water kefirs, Kult does not need to be kept cold during transport and storage. Pasteurisation has stopped fermentation. However, we recommend putting it in the fridge before consumption, as it tastes best at 5–8 °C.
What is the difference between water kefir and kombucha?
Kombucha is made by fermenting tea with a SCOBY colony and often has a vinegar-like aftertaste. Kult water kefir is gentler, fresher, and more palatable even for people who are put off by the typical "smell" of kombucha.
Does Kult Kefir contain caffeine?
This flavour contains an infusion of green tea, so you will find trace amounts of caffeine (theine) in it. However, the amount is fractional compared to a cup of tea or coffee and acts very gently.
Are there artificial flavours or sweeteners in the drink?
Absolutely not. Kult Kefir relies on the Clean Label principle. The taste is created by real passion fruit, green tea, and hops. Only residual sugar from fermentation is used for sweetening, no stevia or erythritol.
Where do the Simcoe hops and passion fruit come from?
All ingredients are of organic quality. The passion fruit comes from certified exotic farms, and Simcoe hops are selected for their high content of aromatic oils, which give the drink a unique zest.
What to buy with hop and passion fruit flavoured water kefir?
- ✔︎ Organic tortilla chips – a crunchy corn snack of organic quality, ideal for the gentle effervescence of kefir.
- ✔︎ Indonesian krupuk crackers – vegan – exotic crunch that pairs perfectly with the fruity-bitter tone of the drink.
- ✔︎ Sesame stick – sesame & flax – sweet natural energy without refined sugar, complements the fresh taste of kefir.
- ✔︎ Beef pieces with chilli & jalapeño – a spicy protein snack, contrasting with the fruity freshness of passion fruit.

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.
