How to Dry Kefir Grains


Once you have established kefir grains, the occasion will arise where either you do not have the fresh milk, or you want to take a break from drinking the fermented beverage. While you can freeze the grains, dehydrating the culture is a better method of storage. Dehydrated kefir grains are viable for up to 18 months in comparison to frozen grains, which have a shelf life of two months or less.

Step 1

Cut clean sheets of cotton fabric to fit the trays of your dehydrator.

Step 2

Place the grains in a strainer and rinse the kefir grains with cooled, boiled water to remove milk residue from the grains. Pat the grains dry using paper towels.

Step 3

Place the grains on the cotton fabric.

Step 4

Place the trays of kefir grains in the dehydrator and replace the lid of the machine.

Step 5

Turn the machine on, dehydrate for 12 to 24 hours or until the grains turn yellow, and become firm to the touch.

Step 6

Place the dried grains in a glass jar. Add 1 tsp. powdered milk to the jar and secure the lid.

Step 7

Store in the refrigerator until needed.
