- Fill a 1-liter swing top bottle halfway with fermented sweet tea from primary fermentation.
- Top off the bottle with organic grapefruit juice so that there is about an inch or two of headspace left in the bottle.
- Add one rosemary sprig to the bottle.
- Secure the bottle lid and gently invert it a couple times to mix.
- Allow it to ferment at room temperature (70-80 degrees F) for 5 Days.
- Carefully open the lid to see if it is carbonated to your liking. If it is, refrigerate; if not continue to ferment for a few more days, then carefully recheck the carbonation.
- Keep refrigerated
