Recipe: Lemon-Lime Water Kefir

This zingy, fizzy, and slightly sweet water kefir is reminiscent of commercial lemon-lime soda. It is incredibly refreshing and requires only a quick squeeze from a couple of handy citrus fruits. This recipe will help you make the best lemon kefir possible!



  • 3 1/2 cups water kefir
  • 1 lemon
  • 1 lime
  • 1 tsp. Sucanat or white sugar (optional)


  1. Remove the water kefir grains from the finished water kefir, and pour it into a quart-size vessel.
  2. Juice the lemon and lime through a sieve to remove the seeds, then pour the juice into the water kefir.
  3. Move this juice to an airtight bottle.
  4. If your water kefir wasn’t very sweet after the first fermentation, add the sugar for extra carbonation.
  5. Swirl the bottles to distribute the juices and sugar. Leave tightly capped at room temperature for up to 72 hours, or until level of desired carbonation and sweetness is achieved.
  6. Store in the refrigerator. Open carefully in case of extreme carbonation and serve chilled.
