Ingredients

  • 1 Gallon Homemade Kombucha
  • 4 cups spring or well water*
  • 3 green tea bags**
  • ½ cup white sugar (organic for vegan-friendly)
  • 2 tablespoons fresh Rosemary
  • 2 grapefruit juiced

Instructions

    Cup of Yum
  1. In a small pot, heat the water to a boil. Add the teabags and sugar, stirring to dissolve. Remove pot from heat.
  2. Allow the tea to steep until very strong, about 8 to 10 minutes. Remove the tea bags and discard.
  3. Add the grapefruit juice, plus grapefruit pulp if desired (adding the pulp will result in a fizzier kombucha). Let the tea mixture cool to room temperature.
  4. Pour the tea mixture (including the grapefruit pulp and rosemary) and the kombucha into a large pitcher (depending on the size of your pitcher, you may have to do this in two batches, using half of the tea and half of the kombucha). Stir well and pour into sealable glass bottles (flip-cap bottles recommended).
  5. Keep bottles in a warm dark room, closet, or pantry for 3 days to allow the kombucha to go through secondary fermentation.
  6. After 3 days, place bottles in the refrigerator. This will slow the fermentation down, but the kombucha will continue to ferment and become fizzier.
  7. When ready to drink, open the bottles carefully because they will have built pressure from the gasses produced during fermentation (look away from the bottles and point them away from your face).
  8. Using a fine strainer, strain the kombucha into a glass–this will catch the grapefruit pulp, rosemary, and the small SCOBY that will have formed during secondary fermentation.
  9. Keep kombucha for up to a month in the refrigerator.

Notes

  • *it is important to use spring or well water because tap water tends to have chlorine and other additives that don’t bode well for fermentation.
  • **Make sure the tea bags are 100% green tea and don’t have any other added peels/spices/ingredients
