Kefir Experiment Day Two

Day two of the kefir experiment. I have just had my second cup. I must warn you though, that if you try kefir, it does not taste a bit like yogurt. When I took my first sip yesterday, I could not believe how tart it was. And I am drinking the strawberry one (that has pureed strawberries in it). I cannot imagine what the unflavored one tastes like. However, I do understand now why people say that it can be used as a replacement for buttermilk. Not sure if I notice anything yet, but then it has only been two days.
