What is kefir grains?
http://www.kefir.net/ How is Kefir Made? Kefir can be made from any type of milk, cow, goat or sheep, coconut, rice or soy. Although it is slightly mucous forming, the mucous has a “clean” quality to it that creates ideal conditions in the digestive tract for the colonization of friendly bacteria. Kefir is made from gelatinous white or yellow particles called “grains.” This makes kefir unique, as no other milk culture forms grains. These grains contain the bacteria/yeast mixture clumped together with casein (milk proteins) and complex sugars. They look like pieces of coral or small clumps of cauliflower and range from the size of a grain of wheat to that of a hazelnut. Some of the grains have been known to grow in large flat sheets that can be big enough to cover your hand!. The grains ferment the milk, incorporating their friendly organisms to create the cultured product. The grains are then removed with a strainer before consumption
