How to make first batch of Kombucha
What you'll need
- Your Kombooch kit: a sterilised 4-litre jar, SCOBY pellicle and 350ml starter liquid, cloth and band
- 3.25 litres of tap water (filtered if possible)
- 1 cup (190g) white granulated sugar
- 8 tea bags of plain black tea (e.g. English Breakfast, Assam, Ceylon) or pure green tea
- Metal or heat-safe spoons (at least 3, can prepare more)
- A large pan (approx. 5 litres)
- Clean tea towel or kitchen towel
Instructions
1. Clean and sterilise:
Wash your pan, measuring cup, and spoons with soap and rinse well.
Fill the pan with water, add utensils, and boil for 10 minutes.
Let everything air dry on a clean towel.
2. Boil the water:
Measure 3.25 litres of water into your clean pan.
Bring to a rolling boil for at least 6 minutes.
3. Add tea bags:
Turn off the heat.
Add 8 tea bags and steep for 15 minutes.
Remove with a sterilised spoon.
4. Add sugar:
Stir in 1 cup (190g) sugar until fully dissolved.
5. Cool the tea:
Cover loosely with a clean towel.
Let cool to room temperature (a few hours or overnight).
You can speed this up with an ice bath or setting up a fan.
6. Measure starter liquid:
Wash your hands, and gently lift and set aside the pellicle into a clean bowl
Measure 350ml of starter liquid.
If your brew spot is below 20°C, use up to 500ml of starter as insurance against mould – it acidifies the tea for safety, but risks making the finished kombucha taste more acidic.
- If you have starter leftover, store in fridge in a sterile, lidded small jar. This will remain viable for 4-6 weeks and can be used in case this batch does not work. (Cold pauses the culture; it wakes up once brought back to room temperature).
Put 350ml back in jar along with the pellicle
7. Add to the jar:
Pour the cooled tea into your jar, with the SCOBY starter liquid and pellicle.
Pour gently to avoid disturbing the SCOBY.
8. Cover and ferment:
Cover the jar with the cloth and secure with the rubber band.
Place in a warm (21-27°C), dark, undisturbed spot.
9. Taste test:
Starting around day 8, taste the kombucha using a sterilised spoon or a clean straw.
It should be tangy with a little sweetness.
Keep fermenting and tasting every 1-2 days until the flavour is just right.
If doing a second ferment, it’s okay if it’s slightly sweet.
