Coconut Water Kefir

This coconut water kefir recipe can be made with water straight from a young Thai coconut, or a good packaged coconut water (choose one with no additives).
Servings4

Ingredients

First Stage Fermentation

  • 1/4 cup kefir grains
  • 6 cups young coconut water

Second Stage Fermentation

  • 6 cups first stage coconut water kefir
  • 1 cup juice of your choice, such as orange or pineapple

Instructions

First Stage Fermentation

  • Combine the water kefir grains and the coconut water in a jar.  Like to cover with a cloth, so I don't have to worry about gas build up.
  • Allow to stand for up to 48 hours at room temperature. You can check every 12 hours to make sure the fermentation isn’t going too far.
    You’ll know if it’s strong enough by taste testing. (The longer you leave it, the more pungent and sour it gets.) After you’ve made a few batches, you’ll get a feel for how you prefer it.
    The more grains you have in the water, the less time it will need to develop.  The 1/4 cup in the recipe will equate to 48 hours.
    Warmer room temperature will also result in quicker fermentation.
  • Strain the coconut water kefir from the kefir grains, reserving the grains for another batch or to grow more. Set the coconut water kefir aside for a second stage fermentation.

Second Stage Fermentation

  • Combine the coconut kefir and juice in a bottle that has a tight-sealing lid.
  • Leave to stand at room temperature for 48 hours. This will cause a second stage fermentation, where the kefir will break down the sugars in the juice and go fizzy.
    Important: You will DEFINITELY need to open the bottle a couple of times a day, especially with juices that have more sugar, to allow the gasses to escape.
    The build up of gas (fizz) will be be enough to potentially smash the bottle if you don't do this.
  • If your kefir is already quite fizzy after stage one, or if you just like the taste of the kefir with the juice without actually fermenting for this second stage, then you can simply add the juice and put it straight in the refrigerator, which will slow the fermentation down.
