- 1.5L jar (I use a round Fido jar with a swingtop lid) or a fermentation crock
- 1L of water
- 2 teaspoons of Black tea
- 70g sugar
- 100ml Kombucha starter
- 1 Kombucha pellicle/SCOBY (optional, but it helps with more sure acidification)
Other proportions, for your convenience:
Water | Sugar |
---|---|
1 L | 70g |
3/4 L | 52.5g |
1/2 L | 35g |
- With some amount of the 1L of water (e.g. 200ml), brew some tea (hot water + tea). Let steep for about 10 minutes.
- Remove tea leaves, dissolve sugar in tea while it’s still warm.
- Put remaining amount of water (e.g. 800ml) in a jar/fementation vessel. Add sweet tea to the vessel
- Once cool, add about 100ml Kombucha starter and pellicle/SCOBY
- Taste in 2-3 days. It should be sweet AND sour.
Continuous Brewing. I tend to only use 800ml of the Kombucha for a second fermentation. The rest, I use as a starter for my next batch. I simply add sweet tea to the original first fermentation vessel.
If it molds, it'll mold during the first fermentation. My rule is, if it's any colour except for beige, I throw it out. Check out examples the [Kombucha subreddit]([https://www.reddit.com/r/Kombucha/search?q=is%20it%20mold&restrict_sr=1](https://www.reddit.com/r/Kombucha/search?q=is it mold&restrict_sr=1)).
- Brewed Kombucha Tea
- Your favourite flavour (e.g. fruits, coffee, etc)
- Second fermentation vessel (MUST be a vessel that can handle a high amount of pressure, else you risk exploding jars)
- Add your brewed Kombucha tea to your second fermentation vessel
- Add "your favourite flavour". Note: you don't need much here, just 2 raspberries or 1/2 of a passionfruit should be more than plenty. The extra sugar will cause extra fermentation and your closed vessel will capture that carbonation. The higher the sugar content, the higher the volatility.
- Put in fridge after a couple of days when you are satistfied with the flavour
Kombucha bottles exploding is a legitimate concern. I tend to do my second fermentation in a mason jar with the gasket removed. I'm not a huge fan of carbonation anyway.
