Temperature for Storage

Water kefir cultures between 68 degrees and 85 degrees Fahrenheit, with the optimal temperature being 75 degrees Fahrenheit.

Once you place your finished water kefir into the refrigerator it will drastically slow down the fermentation process.

In fact, water kefir grains while not in use, can be kept in the refrigerator to encourage the grains to rest or go into dormancy.

How Do You Store Water Kefir Soda?

As mentioned above, storing your completed water kefir in the refrigerator slows the fermentation process.

Once your water kefir has reached your desired taste, it should be stored in sealed containers in the refrigerator.

As water kefir continues to ferment in a room temperature setting, the flavor will change because the sugar content continues to decrease.

Any airtight glass container will be perfect for storing your finished water kefir soda. I highly recommend using glass mason jars.

Mason Jars are easy to find in local stores, or you may already have some if you do any canning. I find that mason jars work great as storage containers.

During your water kefir’s second ferment, mason jars make it easy to release some of the pressure from fermentation. This has also been referred to as burping the water kefir.
