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.
Please Note: This list is for general informational purposes only. We do not test individual batches of water kefir grains for yeast and bacteria content; therefore, we cannot make any guarantees as to the exact probiotic makeup of our water kefir grains.
