Our Circular Mission

We believe in protecting nature and preserving the island we call home. That's why Kosmic Kombucha operates with a circular, returnable glass bottle system.
By paying a small bottle deposit, you help reduce waste, minimize single-use packaging, and keep Fuerteventura beautiful.
Simply return your empty bottles to our brewery or any participating Kosmic Kombucha partner. You can either receive your deposit back or exchange your empty bottles when purchasing fresh Kosmic Kombucha.

It's a simple system with a meaningful impact — helping us keep resources in circulation and reduce our environmental footprint, one bottle at a time.

The Drink

More than just an alternative to soda, Kosmic Kombucha is a living, unpasteurized beverage crafted through a natural fermentation process. Rich in organic acids, antioxidants, and beneficial cultures, it offers a refreshing way to support a balanced lifestyle while delivering complex, naturally developed flavors.
Unlike conventional soft drinks, our kombucha contains no artificial additives and is carefully brewed in small batches to preserve its living character and authentic taste.
We offer two distinct styles, each with its own personality:

Black Tea Kombucha:

Light, crisp, and exceptionally refreshing. Made from green tea, it offers a cleaner flavor profile with delicate herbal notes and a bright finish. An ideal choice for warm days and those who prefer a lighter, more vibrant taste.

Green Tea Kombucha:

To create our unique flavor varieties, we carefully infuse both tea bases with selected food-grade essential oils, creating vibrant and natural flavor profiles ranging from citrus and mint to more complex botanical combinations. This allows each kombucha to develop its own character while preserving the authentic qualities of the fermentation process.
Whichever you choose, every bottle is naturally fermented, alive, and crafted with care on the island of Fuerteventura.

Bold, smooth, and full-bodied. Brewed from premium black tea, it develops deeper, more complex flavors with subtle fruity and earthy notes. Perfect for those who enjoy a richer and more robust kombucha experience.

The Story of Kosmic Kombucha

Kosmic Kombucha was founded in 2025 in Corralejo, Fuerteventura by Kathrin Adrion.

What started as a passion for fermentation and natural drinks became a small local production - a female owned business dedicated and built on curiosity, creativity and a love for natural processes. Small batches of kombucha are brewed in the „fábrica“ in Corralejo, fermented slowly and bottled by hand in returnable and reusable glass bottles.

The name Kosmic is inspired by Kathrin’s children: her son Kosmo and her daughter Moon. Just like the cosmos, kombucha is alive, constantly transforming and full of energy.

Frequently asked questions

How much should I drink?

Kombucha is a food, not a drug or supplement. For this reason, it’s best to think of kombucha like any other healthy food or beverage—there is no known “right” or “wrong” amount to drink. While we always encourage people to drink the amount that makes them feel good, it may be helpful to know that each bottle contains 1 billion probiotics at the time of bottling, which is twice the World Health Organization (WHO) daily recommended amount of probiotics.

Many of us at Kosmic Kombucha enjoy a bottle a day!

As always, it’s a good idea to discuss any dietary changes with your healthcare provider.

How much caffeine is in Health-Ade?

Great question! While our kombucha is brewed using black and green tea, much of the caffeine dissipates during fermentation. Kosmic Kombucha has between 5–15mg of caffeine per serving, similar to the amount in a cup of decaf coffee.

What is kombucha?

Kombucha is fermented tea that contains probiotics and healthy organic acids. Ours is blended with organic cold-pressed juice to create a wide range of feel-good flavors. A little tart and a little sweet, with just the right amount of bubbles, kombucha is a delicious natural treat!

What are the ingredients in kombucha?

Tea, filtered water, sugar and a culture (the collection of microorganisms responsible for fermentation) are all you need to make kombucha! At Kosmic Kombucha we combine green and black tea with carefully selected natural flavours and premium essential oils to create refreshing, feel-good drinks full of character.

What are the benefits of kombucha?

Like all fermented foods, Kombucha contains probiotics and healthy organic acids which are both known to support a healthy gut. A healthy gut contributes to decreased inflammation and bloating, stronger immunity, smooth digestion, balanced energy levels, less stress, healthy skin and nails and improved mood.
