I’m no expert. But, for the first time, I made kefir. It takes all of maybe 5 minutes to drain and start a fresh batch. I do it in the morning because that’s my best time. The nice thing with making kefir is that you choose the time of day that you start it and change it the same time everyday. I was a little intimidate too, but you’ll see it’s one of the easiest things to do. My problem is that I’m having problems consuming it all. I put a batch of grains in the freezer only to read later that I did it wrong. I don’t know whether they’re spoiled or not, I haven’t checked.
Take a try! If it’s too much for you, than at least you tried.
ps. Another vain. I’m not nearly as busy as you, so I do have time. Raising 4 kids, I can somewhat understand. Hope you get your answer soon.
