What you need
- 4 g loose-leaf green tea
- 50 g plain white sugar
- 850 g filtered water
- 100 g kombucha from a previous batch, as starter
- One SCOBY
- About 1 teaspoon (2 to 3 g) of fresh ginger, grated or chopped, for the bottles
Required gear
- Wide-mouth glass jar, 1.5 to 2 liters
- Clean cloth or coffee filter, and a rubber band
- Pot or kettle, for the tea
- Scale accurate to 1 g
- Thermometer
- pH strips (range 2.5 to 4.5) or a pH meter
- Pressure-rated glass bottles with tight caps, for the second stage
- Funnel and fine strainer
Step-by-step protocol
- 0:00Bring 250 g of the water to 80°C. Stir in the sugar until it dissolves, add the green tea, and steep for about 4 minutes.
- +4 minStrain out the tea and add the remaining 600 g of cool water. Let the tea cool to room temperature, below 30°C, before anything else goes in.
- +1 hPour the cooled tea into a clean glass jar, add the starter, then slide the SCOBY in with clean hands.
- +5 minCover the jar with a clean cloth or coffee filter held by a rubber band, so it can breathe but insects cannot get in, and leave it out of direct sun at 20 to 26°C.
- Day 5+Taste a spoonful every day with a clean spoon. It is ready when it is pleasantly tart with a little sweetness left and the pH reads between 2.5 and 4.2.
- Day 7+Lift out the SCOBY and keep it with 100 g of kombucha as the starter for the next batch. Put the ginger in the bottles, half a teaspoon per 16 oz bottle, fill them with the kombucha, leave 2 to 3 cm of headspace, and seal.
- +2-3 dKeep the bottles at room temperature for 2 to 3 days, checking them daily, then refrigerate. Ginger carbonates quickly, so do not leave them longer.
- ThenChill the bottles before opening, open them slowly over a sink, and strain out the ginger as you pour if you like.
Troubleshooting
What it may be good for
How strong is it?
We list about 12 mg for an 8 oz glass, from a batch made with 4 g of green tea per liter. A typical 8 oz cup of green tea has about 28 mg, and bottled kombucha measured in a lab comparison of nine brands ran from about 4 to 27 mg per 8 oz.
Second-stage safety
Use pressure-rated glass bottles with 1 to 2 inches of headspace, and keep them at room temperature for only 2 to 3 days before refrigerating. Ginger speeds carbonation, so a bottle that felt flat on day one can be under real pressure by day three.
What to watch out for
- Kombucha is a live, acidic drink that contains some caffeine and a little alcohol. If you are pregnant or nursing, have a weakened immune system or are prone to acidosis, check with your doctor first. Extension services advise small servings, around 4 oz a day.
- Brew in glass or another non-metal, food-safe container, since the acid can pull metals out of glazed ceramic and metal. Keep everything clean, and throw out a batch that grows dry, fuzzy mold.
Green tea ginger kombucha starts as a light green tea kombucha and finishes in the bottle with fresh ginger, which adds peppery warmth and a livelier sparkle. It is crisp and gently tart, with a fresh, slightly vegetal finish.
Origin & Story
Ginger is where kombucha gets lively. The jar of green tea kombucha is finished and quiet, and the ginger goes into the bottle with it. Two or three days later the bottle hisses when you open it. Ginger speeds up the second stage, which is why it carbonates better than most flavorings and why it deserves a little respect.
It is also a flavor you will find on many kombucha shelves, from several bottled brands, and the reason is easy to taste: a peppery edge gives the tang something to push against, and the green tea keeps the finish fresh and slightly vegetal.
Green tea makes a lighter base than black. In a Polish university comparison, green tea kombucha smelled fresher and more vegetal where black tea's smelled heavier and earthier. Green tea likes cooler water, about 80°C, because hotter water pulls out bitterness before the culture ever sees it.
Give the second stage some care. Use pressure-rated bottles, leave an inch or two of headspace, check them daily, and chill them as soon as they are as fizzy as you like. A warm, lively bottle can foam over, so open it cold, slowly and over a sink.
Steep 4 g of green tea with 50 g of sugar in 250 ml of water at 80°C for about 4 minutes, add 600 ml of cool water, let it reach room temperature, add 100 ml of starter and the SCOBY, and ferment 7 to 10 days; then bottle it with a teaspoon of fresh grated ginger per liter and leave it 2 to 3 days before chilling.

How much caffeine is in Green Tea Ginger Kombucha?
One serving, 8 oz cup (240ml), contains approximately 12 mg of caffeine.
What temperature should I use for Green Tea Ginger Kombucha?
Steep the tea base at 80°C (176°F), then let it cool to room temperature before adding the culture, because heat kills it. Warmer rooms ferment faster and taste more sour; cooler rooms slow everything down.
How long does Green Tea Ginger Kombucha take to make?
Timing: 7-10 days in the jar, then 2-3 days in bottles. Method: Glass jar with a SCOBY, then pressure-rated bottles. Ratio: 4 g green tea, 50 g sugar, 100 ml starter and 1 tsp fresh ginger per liter. Grind or leaf format: Whole loose leaf and fresh grated ginger.
Why does my Green Tea Ginger Kombucha taste bitter?
A bitter or harsh ferment usually traces back to the base, such as tea steeped too long or too hot, or to fermenting past its peak. Steep the base more briefly, let it cool before adding the culture, and taste early. Sharp, vinegary sourness is a different problem: it means the ferment ran too long or too warm.
How much ginger should I add?
About half a teaspoon of chopped or grated fresh ginger per 16 oz bottle, or roughly a tablespoon per gallon, is a common starting point. Add it to the bottles, not the main jar, and taste after two days; you can always add more next time.
Why did my bottle foam over?
Ginger and a little leftover sugar make kombucha carbonate fast, and a warm bottle holds more pressure than it looks. Chill the bottle before opening, open it slowly over a sink, and next time shorten the second stage to two days or use less ginger.
Who should avoid Green Tea Ginger Kombucha?
Kombucha is a live, acidic drink that contains some caffeine and a little alcohol. If you are pregnant or nursing, have a weakened immune system or are prone to acidosis, check with your doctor first. Extension services advise small servings, around 4 oz a day. Brew in glass or another non-metal, food-safe container, since the acid can pull metals out of glazed ceramic and metal. Keep everything clean, and throw out a batch that grows dry, fuzzy mold.
