What is Kefir

An ancient living symbiotic culture

Water Kefir is an ancient living symbiotic culture consisting of over 20 strains of beneficial bacteria and healthy yeasts held in a polysaccharide matrix.


It has been used for centuries as a health promoting, alkalizing and probiotic beverage.


Although stories regarding water kefir grains suggest various origins of the culture, earliest records point to its use by the Old Cossacks in the Caucasus Mountain region.


Water Kefir grains are cultured in a sugar-water solution.  During the fermentation process, sugar is consumed and converted to a range of organic acids, enzymes, vitamins and minerals to soothe and support your gut and energise your mind and body.


The term grains refers to the appearance of water kefir only, they don’t actually contain grains such as wheat or rye etc.  They look and feel a bit like crystals made from jelly!


Real water kefir grains will live forever provided they are looked after and fed properly (yes, a lot like a pet).  You may have seen “kefir starters” for sale.  These are the powdered, laboratory made version of water kefir and they are usually good for one or two ferments only. Whilst still probiotic, kefir starters contain far fewer strains of beneficial bacteria than genuine fresh water kefir grains.


At Old Cossack, we only ever use fresh healthy water kefir grains.


Like its better known cousin culture, milk kefir, water kefir is packed with a broad spectrum of probiotic bacteria. It is a delicious, dairy-free and vegan way to boost the diversity of your gut microbiome.
