What is Water Kefir?

Water Kefir Introduction

Just like the milk kefir, the water kefir is a natural probiotic, composed of various bacteria.


The water kefir grains are translucent and angular, and are formed as a result of the binding of polysaccharides by glucose.


It is about a symbiosis between lactobacilli and yeasts that are present in the mother culture.


If the conditions are optimal, the water kefir grains are constantly renewed.

For its development, this type of kefir needs a base composed of: kefir fruit Grains, still water, sugar, dried fruits (usually figs) and acid fresh fruit (lemon).


The result of the fermentation is a sparkling and refreshing drink, whose texture is similar to those of a soda; its taste is neutral and highly appreciated.What we obtain is a high quality probiotic, a real concentration of bacteria and yeast beneficial for our health.


The drink is slightly alcoholic and contains carbon dioxide, which is actually what makes it fizzy. The alcohol degree is directly dependent on the fermentation time and also on the ingredients that are added into the water.

History of Water Kefir

The name kefir would be derived from the Turkish word keif and would mean well-being sensation.


No one knows exactly where the kefir appeared for the first time, but it is generally accepted that it would be a secular tradition whose origins are in the North Caucasus.


It is assumed that the appearance of the kefir dates back to the days when the nomads were transporting milk in skin bags; it is in these same bags that had held the grains fermentation, a process that turned the milk into a thick drink and gave it at the same time a better conservation.


For the fruit kefir, also known as water kefir, it also could be a way to keep a fruity drink for a few days, avoiding it to turn into something toxic.

Benefits of Water Kefir

Before consuming beverages obtained from water kefir grains and especially in case of health problems, we strongly recommend our users to see a doctor, as only a doctor is certified to prescribe a treatment. The consumption of beverages obtained from water kefir grains can in no way replace the treatment, or if so, the user does this at his own risk and peril.


The water kefir shouldn’t be considered as being a miracle product, but it could have its role to play in the internal body rebalancing. Many modern diseases are the result of an unbalanced diet, intestinal disorders, vitamin deficiency, etc. This gives quite often nutritional deficiencies, stress, tension, etc. Most of these inconveniences are solved once the body balance is restored, and this is where the water kefir could successfully act.


Being a natural probiotic,  the water kefir would be part of so-called functional foods; these are foods that, in addition to their nutritional function, provide physiological benefits, while helping to reduce the risk of diseases and take care of health.

Water kefir beverage acts in a soothing, revitalizing and stimulating way. It gives a well-being sensation. Moreover, the word kefir literally means wellness sensation.

Hygiene compliance Water Kefir

Hygiene compliance is essential while preparing kefir (water kefir, milk kefir) and kombucha beverages; therefore, it is very important to always pay attention to hygiene when it comes to kefir.


If you notice any unusual odors and/or colors, or if mold appears on your kefir grains, you must not drink the beverage that you obtained. The water kefir that gives off a strange smell is usually gray or brown.


Healthy kefir grains have naturally a slightly acidic smell, no aftertaste.


Always use cooking tools easy to maintain (glass jar, fine mesh plastic strainer, small plastic spoon).


In order to wash the cooking tools, there is no need to sterilize them; by cons, always use hot water and dish detergent preferably made of natural products, and take care not to burn yourself when doing this.


For the jar, you can use glass jars for vegetables for e.g., that you can easily find on the market. You must carefully clean the jar before use, as described here.


Mesh plastic strainers and plastic little spoons being affordable, the best is to buy them new and used them only for your probiotic cultures.


Once kitchen tools cleaned as described, you have to let them cool completely, as kefir grains can’t withstand high temperatures. Only after that you can start a new culture.

Water Kefir Tips and Tricks

In order to successfully make water kefir beverages, here are some helpful tips:

  • avoid the use of metal when handling water kefir grains; in fact, metal ions distort the bacilli contained in the kefir;
  • water kefir grains are not to be eaten: they serve only to seed your drink;
  • always respect the recommended dosage: about 50 grams of water kefir grains per 1 liter of water. If the grains grow too much, simply divide them to always keep this proportion. Otherwise, the beverage could be very acid, undrinkable too;
  • bottled still water  or filtered tap water using Brita-type pitchers or devices;
  • hygiene compliance is essential: the container must be thoroughly washed after each culture. Water kefir grains must be rinsed after each culture in cold water, and immediately put back in water;
  • if waste appears during the preparation (figs, fresh fruit, etc.), while rinsing the water kefir grains it accumulates in the hollow of the strainerall you have to do is gently recover the water kefir grains and throw all that you will find in the hollow of the strainer, even if it means sacrificing some kefir « crystals »;
  • if you keep the beverage in the refrigerator, please pay attention to the gas excess that can cause the explosion of the container, especially if it is about sealed, glass bottles; you must leave the gas excess occasionally escape;
  • storing the beverage in the refrigerator slows down the fermentation;
  • some mixtures (fruits, etc.) may eventually damage the water kefir grains and also slow down their development: in this case, it’s always better to keep aside a portion of the grains (for that, please go to How to store the grains chapter) and devote only a part of the grains to the exotic  mixtures;
  • dry fruits with preservatives should be avoided;
  • in order to enjoy all its benefits, the beverage should be prepared as and when you need it and consumed quickly:

Young water kefir (fermented for 24 h) is slightly laxative and mature kefir (fermented for 48 h) slightly constipates.

How to store water kefir grains?

If you take good care of them, the water kefir grains will grow indefinitely.


What to do when we want to keep the grains when we have too much of them, or just during our holidays?


The water kefir grains can be put “on a hold” in the refrigerator crisper compartment, in a non-metallic container, into some sugared water in the same proportion as for the basic recipe: about 50 grams of water kefir grains per 1 liter of water. The water should be in a sufficient amount, in order to cover all the grains. In the meantime, make sure to leave them some space so they can have enough air.


You can also dry the grains on a clean linen in the open air, simply by covering them with a muslin so that dust doesn’t penetrate. This way, you can store them in your kitchen cabinet, in a jar covered with a muslin retained by an elastic. In order to later reactivate the dried water kefir grains, you will have to gradually soak them for 3-4 days in sugared lukewarm water (do not use hot water).The water must be changed gradually, as and when the reactivated grains increase in volume.


It is also possible to freeze the water kefir grains and then let them thaw in the open air.


Please notice that the dried milk kefir grains and the thawed ones usually take longer to reactivate, so you have to be patient.
