Hello,
I have been making keefir for about 5 months now (about 8 oz batches). Some how my grains have been disappearing (Not sure exactly how this is happening). For the last month or so I have found one small grain and made sure it made it back in each time, but now it has disappeared as well. The weird part is that the milk I put in every day is continuing to ferment into Keefir each day. I dont rinse the fermenting vessel (I do scrub it out once a week), and there are always little bits of keefir left in the jar when I put in the fresh milk. I use a nylon strainer and a small wooden spoon with a mason jar to ferment in. Any ideas on what could be happening? I have noticed a light brown film on the top which I didn't before but after reading a bit that is probably just some sort of yeast (it smells yeasty as well, but I have just been eating it). Any thoughts would be greatly appreciated. Not sure if I need to start over with new grains? Not sure if what is being fermented is actually still keefir or something else? I would rather not have to buy more grains but that might be my only option?
Thnaks for your help
