Kombucha is a fascinating beverage with a rich history, created through the intricate interplay of microorganisms during fermentation. Its unique taste, potential health benefits, and the DIY culture surrounding its production have contributed to its widespread appeal.

This article covers all the know-how about brewing your own kombucha. It is your ultimate guide to facts about kombucha and brewing your own kombucha.


Kombucha is a fermented tea beverage with origins dating back thousands of years, believed to have originated in Northeast China. This beverage is created through the fermentation of sweetened tea using a symbiotic culture of bacteria and yeast (SCOBY). The process involves the transformation of sugars into various compounds, including organic acids, gases, and small amounts of alcohol.

Constituents In Kombucha

The primary components of kombucha include black or green tea, sugar, and the SCOBY. Black tea provides the necessary nutrients for the microorganisms in the SCOBY to thrive, while sugar serves as their energy source. During fermentation, the SCOBY metabolises these ingredients, producing a unique blend of flavours and beneficial compounds.

One of the key byproducts of kombucha fermentation is acetic acid, which imparts a characteristic tangy taste. Additionally, the beverage may contain various vitamins, enzymes, and probiotics, which are microorganisms believed to confer health benefits. Proponents of kombucha often tout its potential digestive and immune system benefits, although scientific research on these claims is ongoing.

The Recent Rise In Popularity

Kombucha's popularity has surged in recent years, leading to a wide variety of flavours and brands available in the market. Despite its growing popularity, it's important to note that homemade kombucha production requires careful attention to hygiene and fermentation conditions to prevent contamination.

Brewing your own Kombucha

Brewing your own kombucha can be a rewarding and cost-effective way to enjoy this fermented tea beverage. Here's a detailed guide on how to brew your own kombucha.

Ingredients and Equipment

- 1 SCOBY (Symbiotic Culture Of Bacteria and Yeast)

- 1-2 cups of starter tea (previously brewed kombucha)

- 7-8 tea bags or 2 tablespoons loose tea (black or green tea)

- 1 cup of granulated sugar

- Water (preferably filtered)

- Large glass jar

- Cloth or paper towel and rubber band (for covering the jar)

- Funnel

- Bottles for bottling the finished kombucha


  • Prepare the Tea Mixture

- Boil about 4 cups of water and steep the tea bags or loose tea in it.

- Stir in the sugar until it dissolves.

- Allow the tea to cool to room temperature.

  • Combine Tea And Starter Tea

- Once the tea is cool, transfer it to the large glass jar.

- Add the starter tea from a previous batch or store-bought kombucha.

  • Add The SCOBY

- Carefully place the SCOBY on top of the tea mixture.

- Ensure your hands are clean to avoid contamination.

  • Cover And Ferment

- Cover the jar with a cloth or paper towel and secure it with a rubber band.

- Place the jar in a warm, dark place, maintaining a temperature between 68-78°F (20-26°C).

- Let it ferment for 7 to 30 days, depending on your taste preference. Check the taste using pH strips.

  • Second Fermentation (Optional)

- After the initial fermentation, you can do a second fermentation for added flavour and carbonation.

- Transfer the kombucha to bottles, leaving some space at the top.

- Add ingredients for flavouring like fruit, ginger, or herbs if desired.

  • Bottle and Refrigerate

- Strain out any solid pieces, including the SCOBY.

- Using a funnel, bottle the kombucha and seal the bottles.

- Allow the bottled kombucha to carbonate for a few days at room temperature, then refrigerate.

  • Enjoy

- Once chilled, your homemade kombucha is ready to be enjoyed.

- Pour over ice, and if desired, add a slice of lemon or your favourite garnish.

  • Tips

- Keep everything clean to prevent contamination during the brewing process.

Kombucha is often consumed for its potential health benefits, though it's important to note that individual experiences can vary. Some potential benefits include:-


Kombucha is a source of probiotics, which are beneficial bacteria that can support gut health and digestion.


It contains antioxidants that may help neutralise free radicals in the body, potentially reducing oxidative stress.

Vitamins and Minerals

Kombucha can provide small amounts of vitamins and minerals, such as B vitamins, vitamin C, and others, depending on the tea used.


Some believe that kombucha may aid in detoxification processes in the body, but scientific evidence on this is limited.

Improved Immune Function

The combination of probiotics and antioxidants in kombucha might contribute to a healthier immune system.


In conclusion, brewing kombucha at home involves a bit of patience and experimentation, but the result is a delicious and probiotic-rich beverage that you can tailor to your taste preferences. Remember to practise good hygiene throughout the process to ensure a successful and safe batch of kombucha. It's crucial to consume kombucha in moderation, as excessive intake may lead to adverse effects.
