Grapefruit Kombucha


This grapefruit-flavored kombucha is reminiscent of a grapefruit-flavored soda. However, it boasts a low sugar content and a delightful citrus tang, as well as kombucha’s probiotics and enzymes.


Like all flavored kombucha, this beverage is made through a second fermentation. Be sure to use freshly brewed kombucha in this recipe and cap the lid tightly to create a refreshing carbonated beverage.



  • Juice of 1/2 medium grapefruit or 2 grapefruit segments
  • 1/2 teaspoon sugar
  • Enough kombucha to fill a 16-ounce vessel.



  1. Add the grapefruit juice or fruit + sugar to your 16-ounce vessel.
  2. Fill with kombucha, leaving about 1/2-inch of headspace, depending on the shape of the container.
  3. Cap tightly and allow to culture 3 to 7 days or until kombucha is carbonated to your liking. 
  4. Move bottles to refrigerator for storage.
  5. When you are ready to drink it, open carefully, without shaking, to avoid spilling the bubbly kombucha over the top of the bottle.
