Drying Kefir Grains
Kefir grains may be dehydrated for long term storage of up to 12 to 18 months.
To dehydrate fresh kefir grains, rinse the grains with pre-boiled COOLED water. To remove excess moisture, pat-dry the grains between a pre-ironed cooled white terry towel. Place the grains in between two sheets of pre-ironed white cotton or linen cloth. Leave to dry in a well ventilated warm spot, until the grains become quite firm and yellow in colour. Depending on temperature, humidity and size of the grains, drying may take between two to five days for all the grains to completely dehydrate. Place the dry grains in an airtight jar and store in a cool place e.g., in the refrigerator [do not freeze]. I add a little dry milk powder [DMP] with dehydrated kefir grains, adding enough DMP to completely cover the grains in a jar or in a zip lock plastic bag. Dehydrated kefir grains may be stored for up to 18 months. Although I have discovered that my method of adding DMP, dehydrated kefir grains can remain viable for up to 6 years.
