- Cover the jar and place in a warm spot, 68°-85°F, to culture for 24-48 hours.
- After culturing is complete, prepare a new batch of sugar water, (steps 1-4 above).
- Separate kefir grains from the finished water kefir.
- Place kefir grains in the new batch of sugar water.

Removing Water Kefir Grains from Finished Water Kefir
Option #1: Plastic Strainer
The best method for removing Water Kefir Grains from finished water kefir is to use a Plastic Mesh Strainer. Simply set the strainer on top of a clean jar and pour the entire batch of finished water kefir through the strainer into the jar, catching the grains. Transfer the grains immediately to the new batch of sugar water.
Option #2: Stainless Steel Strainer
A stainless steel strainer may be used for removing water kefir grains from finished water kefir. Avoid strainers made from other metals, which may react with the grains and damage them.
Option #3: Cheesecloth or Butter Muslin
While not the easiest method, using Cheesecloth or Butter Muslin to separate the grains is also possible. If using cheesecloth, use at least a double layer, to avoid losing the grains through the holes in the cloth.
How to Rest Water Kefir Grains
If there ever comes a time when you need to take a break from making water kefir, there are few ways to put your grains on pause. Depending on the length of break you want, you can either refrigerate them or dry them. Just be sure that your grains have been actively culturing for 3 to 4 weeks before you do so.
