This is the standard recipe for 1 gallon. Scale up or down depending on the size of your vessel

Supplies Needed

1 cup organic sugar – you can use white sugar but make sure it says “cane sugar”
4-6 bags tea – for loose leaf, 1 bag of tea = 1 tsp
Kombucha Culture – SCOBY
1 cup starter liquid – retain from top of previous batch or substitute distilled vinegar
purified/bottled water
tea kettle – or pot to boil the water
brewing vessel – glass, stainless steel or oak – you can use food grade plastic, but what with BPA’s, I prefer glass!
cloth cover – NO CHEESECLOTH! The weave is too loose and will allow fruit flies in your brew
rubber band

Make Your Sweet Tea Solution

This is the ingredient that will feed your Kombucha mother culture and turn into delicious Kombucha Tea:

Boil 4 cups of water.
Add hot water & tea bags to your chosen brewing vessel.
Let steep for 5-10 minutes.
Remove tea bags.
Add sugar and stir to dissolve.
Fill vessel about ¾ full with purified cold water – the cold water will bring the temp of the hot water to a level where it won’t kill the yeast (they thrive at lukewarm).
If tea is body temperature or below, proceed to the next step. If not, wait until it cools before completing the next step.

Add Kombucha Culture

Add Kombucha mother. Then add Kombucha starter liquid right on top of the SCOBY.
Cover with cloth cover and secure with the rubber band.
Set in a warm location out of direct sunlight and away from aromatic or greasy food preparation.

 Your Kombucha Brew Begins. You Do Nothing.

Do not disturb for 7 days.
Taste & Perfect Your Kombucha Brew

After 7 days, or when you are ready to taste your KT, gently insert a straw beneath the newly formed Kombucha SCOBY and take a sip. If too tart, then reduce your brewing cycle next time. If too sweet, allow to brew for a few more days, tasting every day or so until you reach your optimum flavor preference for mature Kombucha Tea.
Properly brewed Kombucha has a slightly sharp (acidic), not sweet taste. PH of 3.3
Brewing cycles can vary quite a lot but are normally between 7 days to 2 weeks, though they can be longer under certain circumstances, especially cold.
A cycle or two may be required to determine the ideal taste/time/temperature combination, but you will get the hang of it quickly. Then it’s time to bottle your delicious, healthy Kombucha tea.

Bottling & Flavoring Time

With clean hands, remove both kombucha mushrooms (the new Kombucha baby culture that formed and the original Kombucha mother culture) and place in a clean bowl.
Ladle or pour 2 cups of liquid from the top of your brew over the kombucha cultures. This is your starter liquid for the next batch.
Cover your cultures with the cloth cover and set aside for the next brew.
Find clean, suitable bottles with tight fitting lids.
Place them in the sink.
If you are flavoring your Kombucha Tea, place those flavorings directly into the bottles.
Place a funnel in your first bottle and ladle or pour the Kombucha Tea into the bottle.
Fill to the top for increased carbonation. Repeat for the other bottles, but don’t drink the brown yeast dregs at the bottom, just dump the last 1-2 inches out.
You may choose to strain the brew of any small pieces of kombucha culture or yeast at this stage, though I don’t find it to be necessary.
Screw the lid on and set aside 1-3 days, burping your bottles to let our carbonation and prevent explosions.
Move your flavored bottles of kombucha tea to the fridge when they’ve reached the carbonation/flavor you like.

Repeat for your next batch, and adjust as necessary.
Quick FAQ
How much Kombucha should I drink?

Drink as desired. Start by drinking 4oz of Kombucha Tea on an empty stomach in the morning and see how your body reacts. Try again that evening. If it’s going well, try it 20 minutes before a meal. Listen to your body, drink lots of water to aid the detox, and if you crave more Kombucha, have some more. But like anything don’t overdo it!
Does Kombucha have caffeine?

Kombucha Tea does contain small amounts of caffeine, as it is made from tea. However, Kombucha generally contains only about ⅓ the caffeine of a similar cup of tea. In my guides I teach techniques to dramatically reduce the caffeine content to nearly zero.
How much sugar does Kombucha contain?

Again, this varies based on recipe and ferment time, but most Kombucha Tea will contain less than a teaspoon of table sugar per glass, and it is possible to ferment longer with the Kombucha culture until the Kombucha Tea is essentially sugar free.
What kind of tea is best for making Kombucha?

Nearly any kind of tea or herbal infusion can brew a successful Kombucha batch, but for long term health of the kombucha culture, a mix of green and black tea does best. I offer Hannah’s Special Blend, a tried and tested recipe for the best Kombucha Tea.
I’ve heard it’s best that the Kombucha Mother stay warm. How can I do that?

Kombucha heating mats have always been difficult to use and inefficient, so I decided to invent my own. Check out Kombucha heating solutions.
Can I make it fizzy like the stuff I get at the store?

I recommend trying the first couple of batches without these tricks and you may find the low levels of natural carbonation are enough to please your taste buds. That said, my techniques are tried and tested, so much so that you have to be careful too much carbonation doesn’t build up and lead to an accident!
