5 Stars 4 Stars 3 Stars 2 Stars 1 Star

No reviews

The second fermentation of kombucha transforms plain kombucha into a fizzy, flavorful, soda-like drink. By adding fruit, herbs, or spices, you enhance both taste and natural carbonation, creating a refreshing and healthy homemade beverage.

  • Total Time: 1 day 5 minutes (includes fermentation)
  • Yield: 6 servings

Ingredients

Previously brewed kombucha (from first fermentation)

Fresh or frozen fruit/berries (e.g., strawberries, raspberries, blackberries)

Optional: herbs (basil, mint, rosemary), spices (cinnamon, turmeric), fresh ginger

Instructions

  1. Prepare kombucha from first fermentation using tea, sugar, water, and a SCOBY.
  2. Pour finished kombucha into flip-top bottles, leaving 1 inch of headspace.
  3. Add 1/3–1/2 cup fruit per bottle. Include herbs or spices if desired.
  4. Seal bottles and leave at room temperature for 24–48 hours to ferment and carbonate.
  5. Burp bottles daily (or twice daily if hot) to release pressure and prevent explosions.
  6. After 1–2 days, refrigerate to stop fermentation and preserve fizz.
  7. Serve chilled and enjoy your homemade flavored kombucha.

Notes

  • Citrus Zing: Add lemon, lime, or orange slices.
  • Ginger Spice: Use sliced ginger and a dash of cinnamon.
  • Tropical: Try pineapple, mango, or passionfruit with mint.
  • Herbal: Lavender or rosemary complement berry flavors.
  • Green Tea Base: Start with green tea kombucha for lighter taste.
  • Storage: Keep at room temp up to 2 days, then refrigerate. Consume within 2 days for best flavor.
  • Do not heat—heat destroys beneficial bacteria and carbonation.
