Meet The Brewer

Hey friends, I’m Sarah! I’m in love with home-brewing kombucha and have helped thousands of people all over the world make kombucha in their homes! I created an entire website dedicated to brewing kombucha called Brew Buch, and run an online community of over 50,000 brewers called Kickass Kombucha Brewers (I’d love for you to join)! If you have any questions about brewing, please drop a comment at the end of this post – I personally read and respond to them daily!

The process looks like this:

This post will go into detail about each step in the process of making kombucha. For succinct instructions and metric measurements, jump to the printable recipe card at the end of this post. The general order of things goes something like this (you can jump around this tutorial by clicking the links below):

  1. Make SCOBY (1 to 4 weeks) – to make the “mother”
  2. First Fermentation (6 to 10 days) – to make the actual kombucha
  3. Second Fermentation (3 to 10 days) – to carbonate the kombucha

“Excellent recipe. I’ve tried ten or more online for comparison and this one has the best flavor balance. Not at all vinegary and not too sweet. Will be using for my base from now on.” -Katherine

Before we start, here are some general notes that are consistent throughout the whole homemade kombucha process.

  • No metal or plastic containers. Metal can react with the acidic kombucha, while plastic can house nasty bacteria.
  • Clean is key. A recurring theme in kombucha brewing is that everything must be clean! We’re creating the perfect environment for good bacterial growth, but if a bad bacteria sneaks in it could ruin your batch (and make you pretty sick).
  • Temperature plays a big role. Fermentation goes a bit quicker in warmer temperatures and a bit slower in colder.
  • No mold zone. If you see any mold growing on your SCOBY or in the tea (which I understand can be difficult to discern from the hideous SCOBY but will generally be green, white, or black), then toss your whole batch.

Step 1: How to make a kombucha SCOBY

The SCOBY (symbiotic culture of bacteria and yeast) is the mother of the kombucha, providing bacteria and yeast to ferment the sweet tea, protecting the tea from outside contaminants, and providing a loose seal to keep a bit of the carbonation in. Yes, it’s hideous…but it’s the very essence of kombucha! And the best part? You can make one at home! You’ll need:

  • Water: Tap water is just fine here!
  • White Sugar: Feeds the yeast and bacteria—don’t sub with other sweeteners.
  • Black Tea: Provides nutrients for fermentation. Black tea works best for a strong, healthy SCOBY.
  • Raw, unflavored kombucha: Contains live cultures that kickstart the SCOBY growth. Look for one with sediment at the bottom!

To make a SCOBY, you’ll brew sweet black tea, let it cool, then mix in raw kombucha. Cover and ferment at room temperature for 1 to 4 weeks until a ¼-inch SCOBY forms. Keep the SCOBY in its tea until you’re ready to brew your first batch! Jump to recipe for printable instructions.

Which brand Is best?

Our tried and tested store-bought brand is the GT’s “Pure”. You can find it in most natural food stores.

Important Notes For Making A SCOBY

  • Only black tea. Similarly, the SCOBY doesn’t grow as well with green or fruity teas. By all means, once your SCOBY is big and strong, you can use green tea, but for now, stick with black. The SCOBY doesn’t like decaf tea and will not grow as well if fed it (SCOBY = my spirit animal).
  • No honey. Honey can contain botulism bacteria that, when grown exponentially as bacteria and yeast tend to do in kombucha, can be dangerous.
  • Don’t mess with it! You won’t see anything but a few bubbles in the first few days. But then one day a thin, translucent layer will form, eventually thickening into a full on SCOBY.

Step 2: The first fermentation

So you’ve got a newbie SCOBY and you’re ready to get this komboo-choo train rollin’. This first fermentation is where you actually make the kombucha. You’ll need:

  • Water: Tap is fine!
  • White Sugar: Feeds the SCOBY and bacteria during fermentation.
  • Black or green tea: Black tea is most common, but green tea adds a lighter flavor.
  • Unflavored kombucha: This has the live cultures and acidity needed to start your fermentation.
  • SCOBY: Your live culture pellicle.

To do the first fermentation, you’ll brew sweet tea, cool it, and add it to a jar with your SCOBY and starter kombucha. Cover and ferment at room temp for 6–10 days, tasting around day 6. Once it’s slightly tangy and not too sweet, reserve 2 cups as your starter and move the rest to second fermentation. Jump to recipe for printable instructions.

First Fermentation Tips

  • In this step, unlike in the making of the SCOBY, you can use other teas besides black. Feel free to experiment with green, white, oolong, or combinations of them. Fruit teas should be mixed with a few black tea bags to ensure the SCOBY mama gets what she needs to thrive.
  • Once the SCOBY gets to be about an inch thick, peel off a few layers to create a second SCOBY (you can share the love and gift this to a friend!)

Step 3: The Second Fermentation

The final step and negotiably the best part of the process! The second fermentation is where the real magic happens. It’s where you can play around with sweet, fruity kombucha flavors that will not only make your homemade kombucha taste better than store-bought, but will carbonate the kombucha! You’ll need:

  • Homemade kombucha from the first fermentation
  • Sweetener (fruit, honey, or sugar). Here are a few ideas per 1 cup kombucha:
    • 1 to 2 Tbsp mashed fruit or fruit juice
    • 1 to 2 tsp honey
    • a piece of candied ginger

Strain the kombucha and bottle it with your chosen sweetener, leaving some headspace. Let it ferment at room temperature for 3 to 10 days to build fizz, then strain out fruit if needed and refrigerate to chill and stop fermentation. Jump to recipe for printable instructions.

Second fermentation tips

  • The more sugar/fruit you add, the faster the kombucha will ferment and become carbonated.
  • Your jars can explode if the pressure becomes too high! For your first few batches while you’re still getting the hang of how kombucha reacts to your environment, bottle a portion of it in a plastic bottle. This will act as a gauge for how the others are doing. When the plastic bottle is rock solid, the rest are probably done. “Burp” them by opening each to release some pressure, then place them in the refrigerator to slow fermentation.

Instructions 

Making Kombucha SCOBY

  • Make Tea: Bring 7 cups water to a boil in a clean pot. Remove from heat and add 4 bags black tea. Allow tea to steep for about 15 minutes. Remove tea and stir in ½ cup white sugar. Let tea cool to room temperature.
    Alternatively, boil only 2 cups of water and add the remaining 5 cups of cold water once the tea has steeped and sugar has been added. This will quicken the process.

  • Add Starter: Add 1 cup unflavored kombucha then pour everything into a large glass jar.
    Adding starter kombucha to a pot.
  • Ferment: Cover with a clean cloth and secure with a rubber band. Set somewhere dark and room temperature (70-75°F, 21-24°C) for 1 to 4 weeks, until a ¼ inch (½ cm) SCOBY has formed.

First Fermentation

  • Make Tea: Bring 14 cups water to a boil in a clean pot. Remove from heat and add 8 bags black or green tea. Allow tea to steep for about 15 minutes. Remove tea and stir in 1 cup white sugar. Let tea cool to room temperature.
    Alternatively to quicken this up, boil only 4 cups of water and add the remaining 10 cups of cold water once tea has steeped and sugar has been added.
    Making sweet tea.
  • Combine With Starter + SCOBY: If your SCOBY is still in the jar you made it in, use a clean spoon to push it down into the tea, then pour out all but 2 cups of the tea that’s in that jar (you can bottle the remaining tea to keep as a strong starter kombucha). Pour in your freshly made cooled tea.

  • Ferment: Cover with a clean cloth and secure with a rubber band. Set somewhere dark and room temperature (70-75°F, 21-24°C) for anywhere from 6 to 10 days. Begin tasting the tea at about 6 days. It should be mildly sweet and slightly vinegary when finished.
    The longer the tea ferments, the more sugar molecules will be eaten up, the less sweet it will be. This process will go faster if it is warm in your house.

  • And Repeat: Reserve 2 cups from this batch to use as starter kombucha for your next batch (just leave it in the jar with the SCOBY). The rest can move into the second fermentation!

Second Fermentation

  • Flavor: Add your desired flavors to each bottle, then funnel kombucha into bottles, leaving about 1 inch at the top. Seal each shut.
    Adding flavor to kombucha.
  • Ferment: Let ferment somewhere dark and room temperature for 3 to 10 days.
    This process will go faster if it is warm in your house. Carefully open bottles to prevent volcanoes. You can do this over a bowl with a baggie over the top just in case!

  • Serve: If desired, strain out flavorings before serving. Place bottles in the fridge to slow the carbonation process and to chill before serving.

Supplies Needed for Making Kombucha

  • Large Glass Jug: It should hold at least 1 gallon (buy on Amazon or in most homeware stores)
  • Fermentation Bottles: These bottles have a tight seal specifically designed to keep the carbonation in (hellooo fizz!) (buy flip-top bottles here or collect and reuse GT’s bottles)
Carbo cap kombucha lids.
You can also use these carbonation lids to prevent explosions. They allow your brew to get to a predetermined PSI and let any excess pressure release automatically.

    Sweet! Thank you! This is all so very exciting!

  2. Angela Hennen says:

    I just ordered all the supplies to start making my own Kombucha, but I ordered the loose tea. I’m a bit confused now! I wish I would have ordered it in the bags. Do I just use a strainer to pour it into the gallon containers? And do the same when making my own Scooby?

    1. Sarah says:

      Hi Angela! It’s not a problem, just strain out the loose tea tea infuse. Happy brewing! 😀

  3. Debra says:

    this recipe is so easy to do i loved it more than store bought but i have run into a question i dont know how to keep the mother happy and healthy when not making kombucha

    1. Sarah says:

      Great questions, Debra! You can make a SCOBY “hotel” of sorts with the same sweet tea solution from Step 1 (tea + sugar + starter), then just let it sit in there until you’re ready to brew next. This article has some helpful tips.

    Love your recipes. Just wanted to let you know if you have extra SCOBY the chickens love it and it is good for them too. Unfortunately I don’t know anyone to give extra SCOBY to so my chickens get a treat. Thank you for the easy way to make Kombucha and the how to on making fizzy Kombucha. I always get a little fizz but not much. Now I see what I am doing wrong. Thank you, will use your recipes from now on.

    1. Sarah says:

      Aw, thanks so much Barbara! I’m considering getting chickens, so this is great to know! You can also make a REALLY tasty candy with leftover SCOBYs.

  7. Hannah says:

    Thank you for this! I have been making my kombucha for about a month but I’m finding that after I bottle it (in glass bottled), baby scobys are forming! Each one has jelly bubbles that are either clear or black. I can’t figure out why! Any suggestions?? Thank you!

    1. Sarah says:

      Hi Hannah! Those baby SCOBYs are totally fine (you even see them in storebought bottles of kombucha). Keep an eye on the black ones to make sure they’re not mold, but if everything has been clean and your SCOBY looks good, it’s very likely just healthy baby SCOBYs.

  8. Robert Hathaway says:

    Sometimes our kombucha isn’t clear and has lots of floating material suspended. A friend says it looks moldy and suggested we throw it out. Is it supposed to be clear? What are your thoughts
    Also, when we add juice to get the fizz, is it best to use juice from concentrate or not from concentrate? Thank you

    1. Sarah says:

      Hi Robert! It’s okay for there to be stringy brown floating bits; this is very likely just yeasts and baby SCOBYs (you’ll also see it in store bought bottles of kombucha). Mold will look dry and discolored. As for the juice, you can use either!

  9. Dominic says:

    Thanks for sharing your knowledge here – Someone asked about continuous batch Kombucha a year ago – I wonder if you’ve had a chance to experiment with it? I’m picturing a wide mouth glass beverage dispenser where you can add some amount of input ingredentes per some regular time interval (i.e. 1/2 tbspn sugar, and 1 cup brewed tea each day). I imagine that the amount of stuff you would need to add would be a function of your scobe (i.e. a larger scobe would consume more raw ingredents in one day than a smaller one)…. Also I wonder if the Kombucha ‘separates’ – sugar water is denser than alcohol, for example, so you could expect that at the BOTTOM of the container you have more fermented product and at the TOP (near the scobe) you have more UNfermented product – knowing things like this might help design a continuous kombucha process. Any Thoughts or experience you can share with us?

    Thank you!

    1. Sarah says:

      Hi Dominic! I haven’t actually tried this but really want to. The only think I’m unsure about is the beverage dispenser nozzle, which is usually plastic and could harbor bacteria. Otherwise it sounds like it could be pretty great!

      I also haven’t experience kombucha separating. The alcohol content is so small that I don’t think this would effect it much (and I would imagine when you add the fresh tea, pouring it in would be enough to mix things up).

      Happy brewing and experimenting!

  10. Kade says:

    Have followed your instructions and they have been awesome!
    I’m currently in the “first fermentation process” and I transferred my SCOBYs to the gallon jars. I checked on them today and saw that there was a brown/black glob at the bottom of one of the SCOBYs. I took a pic, but how do I know if it’s mold or just a weird blob from the starter tea I added?

    1. Sarah says:

      Hi Kade! It’s pretty normal for there to be dark stringy globs hanging under the SCOBY, mine also has it! I wouldn’t be concerned unless you start noticing blue/green, dry looking spots on the top of the SCOBY.
