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.
