The difference is that the anti-pollution ability of "Hidden Spirit Mushroom" is not as strong as that of real kefir.

Kefir bacteria is a wild natural yogurt fermenting bacteria. It is a bacterial complex. This series of microorganisms share nutrients, coordinate and cooperate, produce mutually beneficial organisms, and form an overall balance.

Kefir mushrooms are fluffy and white in color, resembling white cauliflower and snow lotus, so they are also called snow lotus mushrooms. Kefir strains like to clump together, and if you find them spread out, it's not healthy.

The biological mechanism of the bacteria in kefir is extremely fascinating and has always been the subject of research by scientists. Kefir does not age and die naturally like humans and animals. If the environment is suitable and nutrients are sufficient, it may grow forever.

Kefir strains contain trace amounts of yeast, and the alcohol content will vary as the fermentation time increases. It is also because of this characteristic that kefir is also called milk champagne. There is a kind of kefir bacteria from Caucasus and Japan, which is one of the cultures in the Caucasus Mountains.
