Flavoured kombucha: how to add flavours to your second ferment

One of my favourite bits about brewing kombucha is being able to flavour it exactly to my liking. Below you’ll find a non-exhaustive list of ideas to flavour your next batch.

How to flavour kombucha

There are three ways you can change the flavour of your kombucha (1) adjust the brewing time (2) change the type of tea used to brew or (3) add fruits, spices, herbs and more when you bottle it. Today I’m focusing on the latter. Once you’ve brewed your kombucha you can drink it straight away, but many kombucha brewers will progress to what is known as the “second fermentation” stage or “2F”. This is where the kombucha is bottled along with fruits, spices, herbs and sometimes a little extra sugar to develop the flavour of the drink and to encourage carbonation. If you buy flavoured kombucha from the store it will have undergone a second ferment.

As a general rule I add about half a tsp of caster sugar to a 500 mililitre bottle of kombucha along with the other flavours I’ve chosen. You can swap caster sugar for brown sugar, granulated, or even honey. I’m not going to suggest exact ratios for how much fruit/spice/herb etc to add as this will depend on the flavour of your original kombucha and your own taste buds. Instead, the list below is here to inspire you when you come to flavour your next batch. If your favourite combination isn’t included in the list, add it in the comments below.

Herbs for flavouring kombucha


Fresh works best when adding herbs to your second ferment but don’t worry if dried is all you’ve got. The stronger the herb the more sparing you will want to be. Kombucha flavoured with fresh herbs should be drunk within 7-10 days.

How long does it take?

Once you’ve added your combination of fruits, herbs and spices to your kombucha, leave it to ferment for another 2 – 14 days at room temperature. Once you’ve got the desired level of flavour and fizz you can store it in the fridge.

Top tips for flavouring and bottling

  1. Invest in air-tight bottles that are designed to store carbonated drinks, these are usually swing top bottles with no corners.
  2. Burp your kombucha regularly to ensure there is no explosive build up of gas!
  3. If you’re worried about a particularly lively batch, open it over the sink or with a tea towel close to hand.
  4. Don’t be alarmed if a new baby SCOBY forms in the bottle this isn’t unexpected.
  5. Think carefully about how you’re going to get the residue of your flavourings out. (A chopstick often comes in handy!)
  6. Invest in a good bottle brush to help wash away any sediment left on the bottom or sides of the bottles.
