Ingredients

  • ½ gallon kombucha from a first fermentation this is not store bought kombucha, 1.9 L
  • ½ cup grapefruit juice 120 mL
  • 2 Tbsp fresh grated ginger
  • 1 to 2 Tbsp honey depending on the sweetness of your kombucha
  • Optional: 1 small sprig rosemary or mint

Instructions 

  • Bottle: Evenly distribute grapefruit juice, ginger, and honey into fermentation bottles. Pour in first fermentation kombucha, leaving 1 to 2 inches free at the top.
  • Optional Flavors: Feel free to add a small sprig of rosemary or mint to bottles at this point (be careful not to overdo it - my bottles with too much rosemary were decidedly not tasty).
  • Ferment: Place in a dark, room temperature area for 3 to 10 days, until it reaches the carbonation level you like. This process will go faster in warmer climates, and slower in cooler climates
  • Enjoy: Chill in the fridge before serving, optionally straining out the ginger fibers. Can be stored in the fridge, tightly sealed, for several weeks.
