Recipe: Grapefruit Kombucha

This grapefruit-flavored kombucha is reminiscent of a grapefruit-flavored soda. 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 finished product.


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


  1. Add the grapefruit juice or fruit and sugar to a 16-ounce vessel.
  2. Fill with kombucha, leaving about ½-inch of headspace.
  3. Cap tightly and culture 3-7 days or until kombucha is carbonated to your liking.
  4. Move bottles to refrigerator for storage.
  5. Open carefully when ready to drink, without shaking, to avoid spilling the bubbly kombucha over the top of the bottle.
