In a bid to improve my gut problems I purchased some live Kefir about 3 weeks ago. I followed the instructions, added it to whole milk and left for 36/48 hours. As expected the first couple of brews where awful and went down the drain. The 3rd & 4th brew were ok and drinkable but since then it has gone downhill, it's very sour and today's brew was totally unpalatable and went straight down the drain. It looks & smells like milk that has gone off!! My Kefir now looks like one lump of cauliflower, I have not used any metal implements at all for stirring, straining etc. Up to now I have strained it the evening and put it in the fridge for the morning.
I wonder if there are there any successful kefir brewers out there with any words of wisdom before I finally give up on it.
