How to Make a Kombucha Scoby?

Are you considering starting making kombucha? Or perhaps you’re noticing your budget for store-bought bottles grow each month? Obviously, you know where to start. And that’s by getting a kombucha scoby!

Making kombucha doesn’t take much. You need tea, sugar, and a starter culture (the kombucha scoby and its liquid).

While this drink is delicious and contains health benefits, everyone agrees that a kombucha scoby is not as attractive. That’s what it takes to save a little on your kombucha consumption!

There are 3 easy ways to find a kombucha scoby:

  • Asking a friend for a “baby scoby”
  • Buying one
  • Making one from commercial kombucha

In this article, we show you how to make your own scoby from commercial kombucha. But if you’re looking for a quick and easy solution, we offer quality kombucha scobys in our online store ;)

Things to Know Before Making a Kombucha Scoby

First of all, you should know that the gelatinous disk is only an accessory to kombucha. The element that enables fermentation is in fact the very lively kombucha that comes with it, also known as the starter or liquid culture.

This contains the majority of microorganisms needed for fermentation (learn more about the kombucha scoby).

To develop a new kombucha scoby, you will need unpasteurized kombucha. Rest assured, the vast majority of commercial kombucha brewers do not pasteurize their kombucha (if you find it in the fresh produce section, it is not pasteurized).

The real challenge will be to find one that is plain (or very lightly flavoured). You can choose one with mild flavours and colours that are similar to tea.

Avoid using kombucha with hops or essential oils, since both of these components are detrimental to the growth of microorganisms.

  • Cover the container with the cloth and rubber band.

  • You just created a kombucha scoby!
