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, so there is no specific amount you need to drink. Like any fermented food, it’s best to find what feels right for your body.

If you’re new to kombucha, we recommend starting with one glass a day and seeing how you feel. This allows your body to gradually get used to the live cultures and organic acids naturally present in kombucha.

Many of us at Kosmic Kombucha enjoy a bottle every day as part of a balanced lifestyle. As always, if you have any health concerns or dietary restrictions, it’s a good idea to consult your healthcare provider.

How much caffeine is in KOSMIC KOMBUCHA?

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 a naturally fermented tea that has been enjoyed for centuries. It is made by fermenting tea and sugar with a living culture of beneficial bacteria and yeast, creating a refreshing drink rich in organic acids, antioxidants, and live cultures.

The fermentation process transforms the tea into a lightly sparkling beverage with a unique balance of sweetness and tanginess. Our kombucha is crafted in small batches and flavored with high-quality natural essential oils, creating vibrant and refreshing flavors while preserving the character of authentic kombucha.

What are the ingredients in kombucha?

Kombucha is made from four simple ingredients: filtered water, organic tea, sugar, and a living culture of beneficial bacteria and yeast (SCOBY). During fermentation, the culture transforms the tea into a refreshing drink with its characteristic tangy flavor and natural fizz.

At Kosmic Kombucha, we brew with either organic black tea or organic green tea and finish each batch with carefully selected natural flavors and premium essential oils.

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.
