Question: are water kefir grains reusable?
Answer: Yes, water kefir grains are reusable. Once a batch of water kefir is finished culturing, simply remove the water kefir grains and place them in fresh sugar water, juice, or coconut water. (Although reusable, it is not advisable to use your only set of grains in juice/coconut water, as this can be very hard on them.
