- Bring filtered water to 80°C (avoid boiling to protect delicate green and white tea). Steep green and white tea leaves for 3–4 minutes, then remove and discard.
- Add sugar to the hot tea and stir until fully dissolved. Allow the sweetened tea to cool completely to room temperature (below 30°C).
- Pour the cooled sweet tea into a large sterilised glass jar. Add the starter kombucha and gently place the SCOBY on top.
- Cover the jar opening with a breathable cloth (muslin or paper towel) secured with a rubber band or lid ring to keep out contaminants while allowing airflow.
- Ferment at room temperature (20–26°C) away from direct sunlight for 6–12 days. Taste from day 6 onwards using a clean spoon / straw until the desired balance of sweet and sour is reached.
- Once fermentation is complete, carefully remove the SCOBY and reserve it along with 200ml of the kombucha as a starter for your next batch.
- Pour the finished kombucha through a fine mesh strainer into bottles. Seal and refrigerate, or leave at room temperature for 1–2 days for a second fermentation to build carbonation and add flavours (see Kombucha F2).
- Serve chilled over ice and enjoy the floral, caramel, and apple notes with a refreshing sour finish.
Tip: Using white tea alongside green tea keeps fermentation gentle and produces a lighter, more floral flavour profile — avoid black tea if you want to preserve those delicate caramel and apple notes.
