How to make Kombucha Soda (second ferment)
Servings: 3 cups
Ingredients
- 3/4 cup organic fruit juice
- 3 cups kombucha (first ferment)
- 1 liter swing-top glass bottle rated for carbonated beverages
Instructions
- Pour the measured kombucha and juice into a clean 1-liter swing-top bottle rated for carbonated beverages, leaving the manufacturer’s recommended headspace. Use another suitable bottle for any excess. Seal and monitor daily at room temperature, away from direct sunlight and heat. Cautiously release pressure daily; timing varies by batch.
- Refrigerate when the batch is ready. Chill thoroughly before opening slowly over a sink, away from your face. Keep finished kombucha refrigerated and continue monitoring pressure; refrigeration slows fermentation but does not stop it completely.
Notes
Use one 1-liter swing-top glass bottle specifically rated by its manufacturer for carbonated beverages. Check that the bottle and gasket are undamaged. Do not use Mason jars, decorative bottles, or parchment paper to improvise a pressure seal.
