I was making kefir really regularly, and it was great. It had a slight sour/tangy smell and taste, and a very small curdy appearance (if that makes sense). I got pregnant about 6 months ago and COMPLETELY forgot about the kefir, what with the constant morning sickness and fatigue. I had it stored in a jar with milk in the fridge all that time. A couple of days ago, I rinsed off the kefir grains, put them in about 8 oz of milk and let them sit on the counter for a couple of days. It seems like the kefir milk smells and looks pretty much like I remember it. Is that even possible after having it sit so long? Would you use it, or make a few small batches and dump them to get the kefir back to 100%?
