Want to brew your own kombucha at home? Well you’re going to need a SCOBY to get started! But don’t worry… it’s simple. Learn how to grow your own kombucha SCOBY in just 10 steps.


Behind every great batch of kombucha, there’s a great SCOBY.

One very healthy “Mother.”

A symbiotic culture of bacteria and yeast.

Yep, basically just a big slimy blob of bacteria. (I’m really selling this whole thing for you, right? 🙂 )

Now, acquiring and getting used to handling the SCOBY is likely the most intimidating part of the kombucha-brewing process.

And to complicate things: it’s not something you can just pick up at the store.


Luckily, you can grow your own kombucha SCOBY!

You just need to get your hands on some quality starter kombucha.

If you have a friend that brews, awesome! Get a couple of cups from her (or, better yet, you could just get a SCOBY from her since they multiply with each brew).

If you don’t (and I didn’t), get your hands on some fresh kombucha from a local brewer or health store — I get mine from Whole Foods. If you live in a state where you can buy black-label kombucha that has a little bit of alcohol in it, choose that.

Please know that not all store-bought kombuchas work effectively for growing your own SCOBY. In fact, I recently had to grow a new SCOBY (I wasn’t able to bring my original with us when we moved across the country!) and had a major failure with one brand before trying a second that worked like a charm. But don’t give up! If you follow the steps below and nothing grows, go ahead and try a different brand.

How To Grow Your Own Kombucha SCOBY in 10 Steps

What you’ll need:

  • 16 oz (2 cups) of starter kombucha
  • 2 organic black, green, or white tea bags, or 2 tablespoons of loose organic tea and a tea diffuser
  • Organic sugar (this is a must; the SCOBY cannot grow without the sugar)
  • A large glass jar (must be glass!). I used a half-gallon glass jar because I have a small apartment and it is easier for me to handle weight-wise, but most people typically use a 1-gallon glass jar)

Keep in mind:

Cleanliness is SUPER important!

All of your instruments (including your hands) must be sterile so as not to contaminate the kombucha. If you think you see mold, do not take any chances and discard the kombucha immediately.

Now, how to grow your own kombucha SCOBY in ten steps:

  1. Boil 2 cups of water, add the two tea bags and stir in 3 tablespoons of sugar until the sugar is completely dissolved.
  2. After cooled to room temperature, pour the sweetened tea into your sterilized jar (I washed mine in hot water with a natural dish soap and then microwaved it for 2 minutes just because I’m paranoid and figure that would kill off any lingering bacteria!) and add the starter kombucha.
  3. Cover with paper towel (preferably doubled-over) or a clean, breathable cloth and secure with a rubber band.
  4. Store in a warm, dry place and leave undisturbed for 5-7 days.
  5. During these 5-7 days, check on the progress of your SCOBY periodically. Things to look for: 1) a white film forming on top of the liquid – that’s your SCOBY! Congrats! 2) Mold – you know what this looks like. If you think you see mold, discard the contents immediately, wash and sterilize the jar, and start over.
  6. When the SCOBY is around ¼ inch thick, “feed” it by adding 2 more cups of sweetened tea (just as you made in step 1).
  7. Cover the mixture and return it to its warm, dry resting place and leave undisturbed
  8. When your SCOBY is ½ inch thick, it’s ready to go! Yay!
  9. Remove the SCOBY with clean hands (cannot stress this enough!) and transfer to new jar for brewing.
  10. Use 8 oz of the mixture (the top of the mixture, not the sediment in the bottom) as your starter kombucha for your first batch of kombucha and discard the rest.

That’s it! Sounds simple, right? And it is.


Best of luck and happy ‘buch brewing!

  1. Step 2, you didn’t mention adding the kombucha starter– but you did below….

    Just wondering if when trying it with a bottle of kombucha, making half would work???

  2. Oh goodness – one of the most important parts! THANK YOU so much for mentioning this!! All fixed.

    I used about a 1:1 ration for tea and starter (2 cups to 2 cups).

  3. Hi, Annetta. I washed mine in hot water with a natural dish soap and then microwave it for 2 minutes – I like being extra cautious!

  4. Hello this is my first time making a scoby I was wondering between step six if you take the scoby out to add the. Extra tea or do you just dump it on top of the scoby that has formed?

  5. I just pour it slowly on top! The SCOBY may sink, but it should eventually float back up. And if it doesn’t it’s not a big deal. Good luck – hope you’re starting to see it grow!

  6. When removing the SCOBY from the jar, does it affect it in any way if the SCOBY is slightly torn? The jar I have it in is wider in the area where the SCOBY is and thinner in the jar’ slip area, so I’m worried that when I remove the SCOBY, it might tear. Just checking. 🙂

    And thank you for this awesome post. It is SO helpful.

  7. ive just come to the industry am researching for more information about this wonderful drink.
    thank you.

  8. Dear Nadia,

    Thank you for the wonderful write up on how to grow our own SCOBY! I’m trying to grow one from a mother a bought from someone. It is on day 5 and a white film has formed on the top. As instructed by you will wiat for it to grow to 1/4 inch thick before pouring in more tea.

  9. If it is naturally flavored then I think that would work! If it has cloves or cinnamon though it may inhibit the growth of the good bacteria though.

  10. Hi, love the site very informative and inspiring. I recently started to make a scoby and am on day 4 at the moment. The only thing that has happened though is some clouds have appeared but no skin has formed . Kitchen is a little cool as it’s winter but does warm up for most of the day. Do you think I should just wait.a tad longer or try again?

    Thanks Jono

  11. If I don’t live near a Whole Foods or somewhere that sells the starter, where is the best place to order it from or does it need to be local?

  12. Thanks so much for all of your help on how to grow my own SCOBY! It has been a topic of a little worry and apprehension for me but your post cleared that up and I am excited to tackle it myself!

  13. if a scoby is needed to make kombucha, and kombucha is needed to make a scoby…

    …then which came first, and how was it made?

  14. Thank you for the article. I should be able to grow my own from here…instead of ordering one online…

    I have 2 questions, though:

    1- I don’t have a microwave…would putting the jar in the oven – as in when making preserves – work for sterilization?

    2- the breathable cloth for on top; would cheesecloth work? Or should it be thicker?

  15. Hi there, I’m about ready to feed my scoby. Do I need to add more kombutcha or just the black tea and sugar? I’m thinking just the tea and sugar but not positive. Help!

  16. hi, why must you remove the SCOBY with clean hands? Can I use a spoon (plastic?) instead? I feel that my spoon being sanitized in dishwasher is cleaner than my hands. Thanks!!

  17. You can’t – you need a SCOBY to make kombucha. But you can use kombucha from the store as your “starter kombucha” though.
