Kefir: The Ultimate Guide to the World's Most Powerful Probiotic Drink

What is kefir?

Kefir is a fermented drink based on milk or sugar water, enriched with natural probiotics . It contains living microorganisms that contribute to healthy intestinal flora. The word "kefir" comes from Turkish and means "feeling of well-being".

Kefir looks like yogurt, but the fermentation process is different. The drink is slightly fizzy, slightly sour in taste, and contains a complex ecosystem of bacteria and yeasts.


Origin and history of kefir

Kefir originated in the Caucasus, where it has been consumed for centuries. The kefir grains were traditionally passed down through families and tribes. In the 19th and 20th centuries, kefir spread to Russia and later the rest of Europe.

The original kefir grains were formed by a symbiosis of lactic acid bacteria and yeasts living in a polysaccharide matrix – a unique ecosystem that continues to reproduce itself.


Types of kefir: milk and water

There are two main types of kefir:

1. Milk kefir

Made from cow's milk, goat's milk or plant milk. It has a creamy texture and contains lactose (unless fermented for a long time).

2. Water kefir

Made from sugar water, often with dried fruit. Ideal for people with lactose intolerance or a vegan diet.
