Primary Fermentation Ingredients

  • 40 grams activated water kefir grains
  • 50 grams organic cane sugar
  • 5 grams molasses
  • 2 grams sea salt
  • 1000 mL water

Secondary Fermentation Ingredients

  • water kefir from primary fermentation
  • organic grape juice, pasteurized



Primary Fermentation Instructions

  1. Prepare sugar-water mixture in a quart-sized mason jar. Add the sugar, molasses, salt and water to the mason jar and top with boiling water.
  2. Stir until the sugar is completely dissolved.
  3. Allow the sugar-water mixture to cool to room temperature. 
  4. Add the activated water kefir grains.
  5. Cover jar with a cloth lid and secure with twine or a rubber band.
  6. Allow kefir grains to ferment the sugar water mixture for 24-48 hours. Taste and smell the mixture to see when it is pleasantly tart and sour.
  7. Strain the grains from the cultured water mixture, and reserve the liquid for secondary fermentation.
  8. Make a new batch of the sugar water mixture, and add it to the water kefir grains to start fermenting your next batch.

Second Fermentation Instructions

  1. Fill a 1-liter swing top bottle about 1/2 full with the liquid from primary fermentation. Add the grape juice to the bottle so that there is about an inch or two of headspace left in the bottle.
  2. Secure the bottle lid and allow it to ferment for 24 hours, then carefully open the lid to see if it is carbonated to your liking.
  3. After 24-48 hours, refrigerate immediately. 48 hours will be more bubbly.
  4. Enjoy over ice with a squeeze of fresh lime juice.
