    COMPOSITION OF WATER KEFIR GRAINS: BACTERIA & YEASTS

    Composition Of Water Kefir Grains: Bacteria & Yeasts



    Water kefir grains consist of a complex polysaccharide matrix, in which live a combination of live bacteria and yeasts existing in a symbiotic matrix. Kefir grain make-up can vary depending on culturing location and conditions, resulting in a highly variable community of lactic acid bacteria and yeasts.

    Following is one scientific study's list of bacteria and yeast strains found to comprise water kefir grains.* The strains listed may include numerous subspecies and variants.
