Coconut Water Kefir

This recipe is made using water kefir crystals, which are different than milk kefir grains. You can use them again and again to make a lot of water kefir. We recommend switching back to feeding it with sugar water every couple of feedings. Coconut water can be a little acidic and hard on the grains if they’re continually left in coconut water.
Course: Beverages

  • Add your coconut water and water kefir grains to a quart mason jar and seal with a lid.
  • Allow to ferment for 24 hours. The coconut water will become slightly cloudy and fizzy/bubbly.
  • When ready, strain your coconut water into another mason glass jar or a glass (if you’re ready to drink).
  • Add your water kefir crystals to fresh coconut water and repeat the process (if desired).
  • Then sit down and enjoy this delicious probiotic drink. Or refrigerate for later.


When making regular water kefir with sugar and water, you want to cover with a cloth and rubber band. But due to the low sugar content of the coconut water, you can use a tight lid.
Also, make a note that the coconut water kefir made with the kefir crystals will sometimes form a clear thin SCOBY on top. You can discard this before you are ready to drink. It won’t hurt anything.
