Bring 2 cups of water to a boil.
Steep 4 tea bags in hot water for 5 minutes.
Remove tea bags and add sugar. Stir until dissolved.Let the hot tea cool to room temperature.
Add the Plain kombucha and cooled Sweet Pumpkin Harvest tea to a pitcher and stir.
Pour the kombucha into flip-top bottles.
Seal the bottles and let sit in a cool, dark place for 3-7 days.
After 3 days check one of the bottles to see if it’s bubbly. Store in the fridge and serve cold.
If it’s not bubbly, leave it out for a few more days. Check each day until it’s carbonated.
