How to Brew Kombucha: A Beginner’s Guide

Kombucha is a fermented tea drink that’s gained popularity for its unique taste and potential health benefits. The fermentation process is driven by a symbiotic culture of bacteria and yeast, commonly called a SCOBY.

This living culture transforms sweet tea into a bubbly, slightly acidic drink through fermentation. Typically, the process can be broken down into two main phases: the first fermentation where the tea becomes infused with the beneficial bacteria and yeast, and then the optional second fermentation for adding flavor and carbonation.

Brewing kombucha at home is a simple process that requires only a few key ingredients and some patience. The process begins with mixing tea, sugar, and a SCOBY, and then allowing it to ferment in a clean, sanitized jar.

Once the initial brewing is complete, which can take between 6 to 10 days, you’re ready to flavor and carbonate your drink through a secondary fermentation. This second stage is where you can get creative, adding in flavors from fruits, herbs, or juices to customize your kombucha to your taste preferences.

Throughout the brewing process, you’ll learn how temperature, time, and ingredients can change the flavor and potency of your kombucha, giving you the freedom to tailor your brew. Keep everything clean and give it time—soon you’ll have a delicious, homemade kombucha to enjoy.

Essential Equipment and Ingredients


To get started with brewing kombucha, you’ll need a few key pieces of equipment and ingredients.


  • A 1-gallon glass jar or larger, for the fermentation
  • Tight-weave cloth or coffee filter, to cover the jar
  • Rubber band or string, to secure the cover
  • Non-metal stirring utensil, like a wooden spoon
  • Bottles, for storing the finished kombucha


  • Filtered water, to ensure no chlorine or chemicals inhibit fermentation
  • Black or green tea, as the base for your kombucha
  • White sugar, to feed the SCOBY
  • Starter tea or vinegar, ensuring the liquid is acidic enough
  • A SCOBY, which you can purchase or grow yourself from a previous batch

With the right setup and patience, you’re ready to dive into the world of home-brewed kombucha.

Brewing Your First Batch

Brewing kombucha at home is a straightforward process that requires just a few key steps and ingredients.

Preparing the Starter Tea

Begin by boiling water and dissolving sugar into it, then steep your tea bags or loose tea leaves. The tea acts as the base for your kombucha and provides nutrients for the SCOBY to ferment.

Once the tea cools to room temperature, remove the tea bags, ensuring no residue is left behind. You’ll need a clean jar for the tea; this is where your SCOBY will do its magic.

The Fermentation Process

Place your SCOBY into the jar of cooled tea with some starter tea from a previous batch to lower the pH and kickstart the fermentation. Cover the jar with a breathable cloth and secure with a rubber band.

Store the jar at room temperature, out of direct sunlight, and allow the mixture to ferment for 6 to 10 days. The length of time you ferment can affect the taste, with a longer period resulting in a more vinegary flavor.

Bottling and Flavoring

Once fermented to your liking, it’s time to bottle your kombucha. Reserve a cup of the liquid to use as starter tea for the next batch.

Pour the kombucha into bottles, leaving some room at the top for any added flavorings or for carbonation to build. At this point, you might want to add fruit juices, herbs, or spices for flavor.

Seal the bottles and if you desire fizziness, allow them to sit at room temperature for a couple of days for a secondary fermentation before refrigerating. Refrigeration stops the fermentation and carbonation process, so your kombucha will be ready to enjoy chilled.
