If you want to take a break in the preparation of water kefir drinks, the grains can be kept in a non-metallic container in
the crisper of the fridge, in some sweet water, and in a sufficient amount in order for the grains to be covered.
As the grains needs to be fed, do not forget to rinse them from time to time and put them back in sweet water.
You can also freeze the grains or dry them.
