Milk Kefir Introduction

These little white balls that look like tiny cauliflowers are what we call milk kefir or Tibetan mushroom.

It is actually about living microorganisms, combined with various yeasts and bacteria.

In the milk kefir grains, yeasts such as Kefir candida and also more than twenty different bacteria can be distinguished, the main ones being the following:

  • Lactobacillus bulgaricus caucasicus
  • Lactobacillus bulgaricus casei
  • Streptococcus lactis

By fermenting in animal milk (cow's milk, goat's milk, etc.) we obtain a beverage called exactly as the grains, namely milk kefir: it is a slightly gaseous and acidic beverage, whose texture  resembles strongly to a yogurt one.

No one knows exactly the origin of the milk kefir. It is generally accepted that it would be a native of the North Caucasus secular tradition.


For the Muslim populations of this area, the kefir was considered as a gift from Allah. According to the legend, the tribes had received the milk kefir grains from the hands of the Prophet Mohammed himself, as they were crossing the area about 1400 years ago.


That is the reason why the milk kefir grains are also known under the name of Prophet's millet and the beverage obtained from these grains, the Drink of the Prophet.

Benefits of Milk Kefir

Before consuming beverages obtained from milk 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 milk kefir grains can in no way replace the treatment, or if so, the user does this at his own risk and peril.


The kefir milk 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 milk kefir could successfully act.

Hygiene compliance Milk Kefir

Hygiene compliance is essential while preparing milk kefir beverages. Therefore, it is very important to always pay attention to hygiene when it comes to kefir.


If you notice any unusual smell and/or colors, or if mold appears on your kefir grains, you must not drink the beverage obtained. Milk kefir grains that smell strange are usually grey or brown.


Healthy kefir grains have naturally a slightly acidic smell, no aftertaste. Always use kitchen tools easy to maintain (glass jar, fine mesh plastic strainer, small plastic spoon).


In order to wash the kitchen tools, you do not have 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 the kitchen tools are 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.

Milk Kefir Tips and Tricks

In order to successfully make milk kefir beverages, here are some helpful tips & tricks:

  • avoid the use of metal when handling milk kefir grains; in fact, metal ions distort the bacilli contained in the kefir;
  • milk kefir grains are not to be eaten: they serve only to seed your drink;
  • always respect the recommended dosage: use about a tablespoon of kefir grains into 250-300 ml animal milk. If the grains grow too much, simply divide them to always keep this proportion. Otherwise, the beverage could be very acid, undrinkable too;
  • use preferably whole or semi-skimmed animal milk. In fact, the whole milk strengthens the kefir grains , as it contains all the nutrients that the grains need for their development, while the skim milk weakens them. Do not use fortified or "easy to digest" milk;
  • avoid using constantly the same type of milk, as kefir grains bacteria appreciate the variety;
  • if the kefir grains ferment hardly, simply add a little bit of sugar;
  • hygiene compliance is essential: the container must be thoroughly washed after each culture. Milk kefir grains must be rinsed once per week in bottled still water and immediately put back in milk;
  • stir the milk from time to time, as the milk casein (milk proteins) tends to clump and form around each seed; using a small plastic spoon, carefully stir the grains so that they can disengage and inoculate more homogeneously the beverage;
  • if whey appears at the bottom of the jar, simply stir a little bit with the little spoon: the beverage becomes immediately more sparkling. This also means that the kefir drink is ready and the fermentation should be stopped;
  • respect the fermentation time, as it varies depending on the temperature (18-25° C). At more than 25° C the fungus works faster, while below 18° C the fermentation is slower; if the fermentation is too important, it will give a sour taste and it is not recommended to drink the beverage obtained;
  • the effect of the drink varies according to the degree of fermentation:

young kefir (fermented 12h to 24h) is slightly laxative, therefore indicated against constipation for e.g. The kefir is not very thick yet, it has some little bubbles and its taste is not very pronounced;


medium kefir (fermented 24h to 48h) has already bubbles, it becomes thicker and the taste is comparable to a yogurt one;


mature kefir (fermented 48 h to 72 h) slightly constipates, and it is rather used in cases of diarrhea.

Animal milk or vegetable "milk"?

Milk kefir grains mainly feed on ingredients found in animal milk (cow's milk, goat's milk, etc.).

For people who do not wish to consume animal milk, the use of vegetable "milk" (soy milk, almond milk, etc.) is an alternative, provided that kefir grains are regularly returned to animal milk.


Please pay attention to the fact that using only vegetable "milk" will result in the loss of grains over time because they do not find the nutrients they need.
