What are live kefir grains? To answer that question we first have to ask “What
is Kefir?”
According to the online dictionary merriam-webster.com:
ke·fir “noun \ke-ˈfir; ˈkē-fər, ˈke-\) is “a beverage of fermented cow’s milk.”
Wow! That is a rather general term that can mean just about anything having to do with milk…any kind of milk. Let’s see if we can narrow the answer to the question down a little bit. Wikipedia.com states:(https://en.wikipedia.org/wiki/Kefir#cite_note-Prado-3)
Kefir or kephir (/kəˈfɪər/ kə-FEER),[1][2] is a fermented milk drink similar to a thin yogurt that is made from live kefir grains, a specific type of mesophilic symbiotic culture. The drink originated in the North Caucasus, Eastern Europe and Russia,[3] where it is prepared by inoculating cow, goat, or sheep milk with live kefir grains.[4]
Note: I have inserted "live kefir grains" for "kefir grains". As we shall see later, there is a distinction between live kefir grains and kefir grains.
Now we’re getting somewhere. We have limited the choices of milk to three types, and have learned that kefir is made with something called “kefir grains”. The types of milk are pretty simple to understand. Most people know about milk from cows and goats, and some even know that you can get milk from sheep, but I am curious to find out about these kefir grains. We’ll get to that a little later.
A few more searches and we find that kefir is a probiotic (meaning it’s good for you) fermented milk product that has a creamy texture, can be a little tart to the taste, can be a little fizzy and can contain slight amounts of alcohol from the fermentation process.
