Kefir or kephir (/kÉËfir/ kÉ-FEER), alternatively milk kefir, or bÃºlgaros, is a fermented milk drink that originated in the north Caucasus Mountains made with kefir grains, a yeast/bacterial fermentation starter. It is prepared by inoculating cow, goat, or Sheep milk with kefir grains.
Over a period of 24 hours or so, the microorganisms in the kefir grains multiply and ferment the sugars in the milk, turning it into kefir. Then the grains are removed from the liquid, and can be used again. So basically, kefir is the drink, but kefir grains are the âstarter kitâ that you use to produce the drink.
