How to Make Kombucha

By now, hopefully you've read my post on why you might want to make your own kombucha, as well as the post on how to make a SCOBY (or mother) for kombucha. Today, I'm going to show you how to make kombucha itself. It's easy peasy.

But before I get into that, I wanted to share "6 Surprising Health Benefits of Fermented Food." Yes, I was aware fermented foods (like kombucha, fermented sauerkraut, and yogurt) contained stomach and digestion helpers, and that they also give a boost to your immune system. But I didn't know that fermented foods boost your body's ability to absorb nutrients, improve brain function, treat PMS and ADHD, may aid in weight loss, and more. Check it out.

What You Need to Make Kombucha

Making kombucha is very similar to making the SCOBY for kombucha. It's likely you have everything you need already in your kitchen.

A non-reactive large pot
One 1 gallon glass jar (or 2 half gallon glass jars)
A non-reactive stirring spoon
A non-reactive funnel (optional)
Cheesecloth or coffee filter
A length of string, rubber band, or scanning jar screw band
Bottles or jars (for bottling the finished kombucha. I recommend the type that has a flip top cap because they are less likely to burst should you happen to let the drink over-ferment. But you can use any type of glass container you like, including canning jars or used store-bought glass bottles or jars.)

You will also need

14 cups water
1 cup granulated cane sugar*
8 bags black or green tea, or a mixture of both (You can also use 2 tablespoons of loose tea)
2 cups starter kombucha (This can be the same unpasteurized, store bought kombucha brand you used for making the SCOBY. I used Synergy brand. Or you can use a bit of kombucha made by a friend. After you make your first batch of kombucha, you'll be able to use 2 cups of your own kombucha as a starter for another batch. Plain, unflavored kombucha is recommended, but if you can only find flavored kombucha, use the most neutrally flavored kind you can. I did this, and my finished drink turned out great.)

How to Make Kombucha

1. Thoroughly wash everything you'll use to make the drink. This helps prevent bad bacteria from ruining the finished kombucha. Wash all tools and jars/bottles in warm, soapy water, or run them through the dishwasher. Wash your hands thoroughly, too.

Make the base (sweet tea):

1. Pour the water into the pot and bring to a boil. Remove from heat and add the sugar. Stir until dissolved. Add the tea and steep until the pot is completely cooled.

2. Remove the bags (or strain out the loose tea by pouring it through a fine strainer or a colander lined with a double layer of cheesecloth). Pour in the starter kombucha.

3. Pour the mixture into the 1 gallon jar (or 2 half gallon jars).


4. With freshly washed hands, remove the SCOBY from the jar you used to make it in (or your last batch of finished kombucha). Place it in the jar containing the sweet tea mixture. (If you only have one SCOBY, but two jars for fermenting kombucha, cut the SCOBY in half using a knife freshly washed in hot, soapy water. Place one SCOBY in each jar.)

I use 2 half gallon jars to ferment by kombucha, so I cut my original SCOBY in half and put one half in each jar.
5. Cover the jar(s) with a double layer of cheesecloth or a coffee filter. Secure in place with a rubber band, a piece of string, or a canning jar screw band.

6. Keep the jar(s) at room temperature, out of direct sunlight. Allow to sit and ferment for 7 - 10 days. At 7 days, dip a freshly washed spoon in the jar, and taste the drink. If you like the flavor, move on to the next step. If you'd like a less sweet flavor, taste the kombucha over the next several days, until you're satisfied. Remember, the longer you let the drink ferment, the less sweet it is and the more alcohol it has in it. (Concerned about these issues? Check out this post for more information.)

During the fermenting process, the SCOBY may float, sink, sit sideways, and/or have "strings" hanging down from it. This is all completely normal. The SCOBY will also grow each time you use it. Sometimes the new growth doesn't attach to the old SCOBY; that's fine, too.

Starting a New Batch:

7. Once you're satisfied with the flavor of the kombucha, it's time to begin a new batch. Prepare the sweet tea, as outlined in steps 1 - 3, above.

8. Wash your hands well, then remove the SCOBY from your finished kombucha. Transfer to the jar(s) containing the unfermented kombucha you just started. Cover and ferment. (See steps 4 - 6.)

Bottling and Second Ferment:

9. Pour the fermented kombucha into glass jars; using a funnel helps. (Hint: If your jars have narrow mouths, use a new, clean automotive funnel.) Important: Leave at least 1 inch of headspace at the top of each bottle. If you'll be adding anything to flavor the kombucha, leave at least 2 inches of headspace.)

10. If you want to flavor the kombucha, add the flavoring now. (For example, add a tablespoon or two of real fruit juice; or a 2 inch square piece of lemon (with the rind, cut into pieces); or 2 strawberries (cut up), a 1 inch square piece of lemon (with the rind, cut into pieces), and 4 crushed blueberries. For those who aren't as excited about the sweet/tart flavor of kombucha, I recommend the berry mixture.) Hint: When adding fruit pieces, be sure to chop them up quite small, so they easily fit down the neck of your bottle. Because otherwise, when the drink is fully consumed and you want to wash up the bottle, you'll have a heck of a time getting those fruit pieces out. Not that I've ever done that. Um...yeah.

11. Put the lids on the jars. The kombucha may now be consumed - or, to make it fizzy, you may do a second ferment: Store at room temperature, out of direct sunlight, for 1 - 3 days. Check every day for fizziness. You'll know the drink is carbonated and fizzy as soon as you open the lid, because you'll either hear a whoosh or air, a "pop," or the "crinkly" sound fizzy drinks make. It's perfectly fine if some bottles get fizzy before others. Putting fruit in the bottles seems to slow carbonation. Headspace and room temperature makes a difference, too. And I think some bottles get more of the "mother" in them than others, which also alters the rate of carbonation.

Important: Remember to measure out and set aside 2 cups of your finished kombucha, so you can use it as a starter for your next batch.

12. Refrigerate the kombucha to stop fermenting. Consume within a month.

* Cane sugar is non-GMO (as opposed to granulated sugar made from beets, which is usually GMO. Granulated sugar not marked cane sugar is typically GMO beet sugar.) Cane sugar feeds the SCOBY best. However, molasses, honey (but not raw honey, which may contain bacteria that could adversely affect the SCOBY), and maple syrup may be used, too. According to Kombucha Kamp, use a 1:1 ratio when using molasses, or 7/8 cup of honey, or 1/2 - 2/3 cup of maple syrup in place of the granulated sugar in this recipe. Expect the fermentation process to take longer when not using cane sugar. (Unlike Kombucha Kamp, I do not recommend using Agave, because it is highly processed and actually very unhealthy.)
