properties of kefir

Put the granules and the milk in the container. If it’s not big enough, try leaving at least two fingers free at the top.

It is left between 12 hours and 48 hours, depending on the usefulness you want to give it.

To make water kefir it’s exactly the same, the only difference is that we will add 2 or 3 tablespoons of sugar (better if it’s whole cane sugar or panela). The bacteria will feed on this sugar. After 24 hours, and even better, at 48 hours, water kefir is more than capable of providing us with its probiotic properties.

It is recommended to avoid metallic materials, such as spoons and colanders, and to use other materials instead. The metal could kill bacteria.

kefir care

Water kefir and milk kefir require almost daily care. It is so if we want it for one evil or another. As in the above example, for digestive problems, kefir changes properties if it is fermented for a single day or if it is fermented for 48 hours.

It should be stored at a temperature of around 17 to 20°C, out of direct light and preferably in the dark.

It can be kept in the refrigerator to interrupt the process, and thus keep the ferment for a while. This in case we want to continue using it but we don’t want it to get damaged.

It can also be frozen. In this case, when we want to reuse it, we have to defrost it and the process of creating kefir is activated again.

where to buy kefir

Kefir, both milk and water, can be purchased from dieticians, herbalists and specialty stores ready to drink. It is also available in some supermarkets and department stores.

Although the most common form is already processed (as water kefir or yogurt kefir), it is possible to find the granules of the bacteria that create the drink. These can be purchased at health and herbal stores. Note that each time they feed and create more kefir, their size increases. You can separate it and give it to your friends or family.

Dangers and contraindications of kefir

Like many products beneficial to health and the body, kefir also has certain contraindications.

For example, when you suffer from a chronic or serious digestive disease, you should consult your doctor before you start taking it.

Another thing to keep in mind is that although the bacteria can be frozen, it is recommended that you do not freeze the drink once it is created, as the benefits will be diminished.

And, very important, if you notice that the granules look different, are strange or slimy, and have a strong odor (usually it’s odorless), it’s most likely bad. . In this case, you must throw them away.
