Kombucha in South Africa: Brew Your Own Fizzy Fermented Tea

Published: 04 September 2026

I still remember the first time I tasted a proper home-brewed kombucha. It was tangy, lightly sweet and fizzy enough to make my tongue sit up and pay attention. That little buzz in the mouth is part of the fun, but the real magic is watching a jar of sweet tea slowly become something completely different.

Here at Fermentastic, I make raw, unpasteurised fermented foods in small batches near Bela-Bela in Limpopo. Kombucha is a lovely next step for anyone who enjoys learning what happens when we give living cultures time, warmth and the right ingredients.

What is kombucha?

Kombucha is fermented tea. It starts with brewed tea, sugar, a kombucha SCOBY and some mature starter liquid. The sugar feeds the culture during fermentation, while the tea gives the brew its flavour and character.

SCOBY stands for Symbiotic Culture of Bacteria and Yeast. It is not a mushroom, although people sometimes call it one because of its rubbery appearance. It is a living culture that works together to change sweet tea into a tart, refreshing drink.

Five interesting things about kombucha

1. It is a tiny ecosystem

A SCOBY is made up of different yeasts and bacteria living together. The yeasts help break down the sugar, and the bacteria help create the acids that give kombucha its familiar sharpness. It is fermentation teamwork in a jar.

2. The tea matters

Black tea is a reliable place to start because it gives the culture what it needs and produces a full, familiar flavour. Green tea can be used too, but I prefer keeping the first brew simple while you learn how your culture behaves.

3. Fizz comes later

The first fermentation is where the tea develops its flavour and acidity. The bubbles usually become more noticeable after bottling, when a little of the remaining sugar is fermented in a closed bottle. Open carefully. Kombucha can be surprisingly lively.

4. Every kitchen makes a slightly different brew

Temperature, brewing time, tea, sugar, the size of the jar and even the season can change the result. A warm Limpopo summer brew may move faster than one made during a chilly week. Taste is your best guide, as long as you are also following sensible fermentation and storage practices.

5. Your culture can keep going

Once you have finished a batch, reserve some mature kombucha as starter liquid and keep the SCOBY for the next brew. With care, one culture can become the beginning of a regular home-brewing rhythm.

What are the health benefits of kombucha?

Kombucha is often advertised as a miracle drink, a detox and a cure-all. I do not make those promises. It is a fermented tea, not medicine, and it should not replace proper medical advice.

What I can say is that kombucha is an interesting food made through fermentation. Black tea naturally contains plant compounds, fermentation creates organic acids, and a raw, unpasteurised brew may contain living cultures. The exact result depends on the tea, the culture and how the kombucha was brewed and stored.

Many people enjoy kombucha because it is tangy, refreshing and less ordinary than another sweet drink from the fridge. For me, the pleasure is also in the process: making something patiently, tasting it as it changes, and learning what my culture likes.

How to start brewing kombucha at home

My Fermentastic Kombucha Starter Kit is designed to give beginners the main things they need to start. It includes a 3L brewing jar, 8 black-tea teabags, 1 cup white sugar, 125ml kombucha starter liquid and a SCOBY culture. The ratios are set up for 2.5L of water.

If you already have your own brewing jar and ingredients, the standalone Fermentastic Kombucha SCOBY with starter liquid is the simpler option. It is also useful for repeat brewers who want to keep a new batch going.

The basic process is straightforward: brew the tea, dissolve the sugar, let it cool properly, add the starter liquid and SCOBY, cover the jar with a breathable cloth, and let time do its work. Taste as you go. When it has the balance of sweetness and tang that you enjoy, bottle it carefully and chill it.

What can you make with kombucha?

Plain kombucha is delicious when it is cold and lively. You can also experiment with ginger, berries, herbs or citrus during a second fermentation. Start with small amounts and write down what you used. That is how you find your favourite combination instead of making the same mystery bottle twice.

If you enjoy the gentle sourness of kombucha, you may also like the rest of the Fermentastic range, including raw sauerkraut, kimchi-kraut and fermented chilli sauces. They all have their own flavours, textures and personalities, and they are made for people who appreciate food that is alive with character.

A final word from my kitchen

Kombucha is not instant. That is exactly why I like it. You make a jar, wait a little, taste it, adjust your timing and learn. Then one day you pour a glass, see the tiny bubbles rising, and feel that fizzy little buzz across your tongue.

If you are in South Africa and ready to start brewing at home, have a look at the Fermentastic Kombucha Starter Kit or the standalone SCOBY. I ship Fermentastic products nationwide from near Bela-Bela, Limpopo, and I would love to hear what flavour you make first.
