Super drink: How to preserve Kefir at home

Kefir is not only good for your health, both to drink and to use on your skin. It also reproduces at high speed. If you make kefir at home you will soon ask yourself, how should I keep it?

Kefir should always be kept in whole milk or sugar water (unfiltered water and unrefined sugar).  You can prepare the desired amount of kefir, as long as there is 1/3 of air in the container.

The reason for this is that during the fermentation a gas pressure is created that increases as the temperature rises. The container can be filled more if it is not sealed tightly, so that the produced gas can escape.

If you prefer water kefir, use 1/4 cup of sugar per 4 cups of filtered water.

The utensils used (container and strainer) should not be made of aluminium, because this material is not stable in an acidic environment.
