What is Water Kefir?

Water kefir (or as we like to call it, Kefir Soda) is a lightly sparkling, fermented drink made with Water Kefir Grains, water, and natural sugars. During fermentation, beneficial bacteria and yeast transform the sugars into a refreshing, probiotic-rich beverage that’s naturally low in sugar and full of flavour.
