How to Maintain Kefir Grains. Kefir is a cultured milk beverage that originally hails from Russia. It is made by fermenting milk (whether from a cow, goat, or sheep) using both yeast and bacteria. With a sour, creamy taste similar to yogurt, kefir is touted for its probiotic benefits.. Place the kefir grains into a glass or plastic jar. When you receive your kefir grains, you can choose to rinse away some of the fat solids if desired, but do not use chlorinated water. The chlorine will kill the microorganisms in the grains.
