What is a Scoby?

A Scoby is a Symbiotic Culture of Bacteria and Yeast, or SCOBY for short. It is the starter culture for making kombucha, a fermented tea beverage that has been enjoyed by cultures around the world for centuries. The SCOBY looks like a thin pancake-like disk that floats at the top while fermenting the kombucha tea. It is made up of many different types of bacteria and yeast, all working together to turn sweetened tea into a probiotic-rich, tangy tonic full of beneficial enzymes and acids.

The process for making a Scoby from scratch involves combining water, sugar, tea and starter culture (a sample of an existing Scoby). As the mixture sits in a warm place, bacteria and yeast will start to form on top of the liquid. Over time, this forms a new Scoby that can be used for making kombucha at home.

Why grow your own?

Growing your own Scoby offers several advantages as:

  • Having a Scoby on hand allows you to have fresh, homemade kombucha whenever you want it.
  • Plus, it’s a great way to save money since purchasing starter cultures can be expensive.
  • Having control over the entire process means that you know exactly what goes into your kombucha, so you can be sure that it is free of any unwanted ingredients or contaminants.
  • It also gives you the opportunity to experiment with different types of tea and additives, as well as customize the flavor of your kombucha.

How to make kombucha scoby at home

Ingredients to make a SCOBY

  • 8 cups of filtered water
  • 1 cup organic white sugar
  • 4-6 tea bags or 4 teaspoons loose leaf tea
  • 2 tablespoons starter kombucha (already brewed kombucha from a previous batch)

Supplies needed to make a SCOBY

  • 1 gallon glass jar
  • Cheesecloth
  • Rubber band


  1. Boil the water in a pot on the stove. Once boiling, add the sugar and stir until it is completely dissolved.
  2. Remove from heat and add the tea bags (or loose leaf tea) and allow to steep for at least 20 minutes.
  3. Pour the sweetened tea into a gallon-sized jar or container with a wide mouth (1 gallon is the size of a typical Scoby).
  4. Add the starter kombucha and stir until combined.
  5. Cover the container with a breathable cloth or paper towel and secure with a rubber band or string. This will allow air flow into the mixture while keeping out any unwanted critters.
  6. Place in an area with a consistent temperature of 72-78 °F and let sit for 7-10 days.
  7. After the 7-10 days, you should have a new and healthy Scoby! Carefully remove it from the jar and place it in a covered container with some of its liquid for storage.
  8. You can also use the remaining liquid for your first batch of homemade kombucha. Enjoy!

Things to note when making your kombucha SCOBY

  • Make sure to use organic ingredients as this is important for the health of your SCOBY.
  • Start with filtered water, as tap water may contain chlorine or other chemicals that can be detrimental to the bacteria and yeast in your SCOBY.
  • Use a breathable cloth or paper towel cover when fermenting, not a lid.
  • Keep the fermentation process in a warm area, as this will help the SCOBY form more quickly.
  • Use caution when handling your Scoby, as it is a living organism and can be fragile at times.
