Last night , the kefir was done culturing, and tasted almost like buttermilk when I put it in the fridge to chill overnight. I love buttermilk; so this seemed to be just the perfect length of culture time. This morning, I woke up thinking that I wanted kefir, and barely even drank the coffee. In fact, the coffee tasted terrible to me this morning, through no fault of the coffee, I am sure. I sipped a half cup of kefir with a crystal or two of the Himalayan sea salt added for the minerals, and it tasted like the most delicious drink imaginable. I guess my body was telling me that I was in need of the vitamins and enzymes from the kefir; and I put another quart out to culture because the rest of this batch will be gone by tonight or in the morning at the latest. I have a good energy level today, my feet don't hurt. Actually....... Nothing hurts ! Good news, there, for sure.
