To take a break from making water kefir, prepare a sugar-water solution, place the grains in the sugar water, place a tight lid on the container, and place it in the refrigerator. This will keep for a couple of weeks in your fridge. After that, you need to replace the solution with fresh water and sugar. For each one-quarter cup of water kefir grains, you will need to use one-quarter cup of sugar and one quart of water for the sugar-water solution.
