Perhaps you’re letting your kefir mature too long?

When I first started I did that say thing – and indeed every batch was sour and I drank it because I knew it was good for me not because I liked it much. Then I started to make kefir in shorter amounts of time (a day…less than a day etc.). Experiment and you should be able to get your kefir so it’s not so sour…

Probably, but young kefir does not have nearly as much benefit from what I have read on Dom's site, and on the Kefir email list, and it also retains much more lactose, and hence more carbohydrate, which I wanted to avoid (the carbs that is). And the kefir I used to make kefir cheese was not the young kefir, as best I recall. I'm going to pick up some milk today and start reviving my grains if they are still viable. I was able to revive them in under two weeks previously after they had been frozen for at least 18 months. But even the young kefir gave me the GI adventures, interestingly, eating the grains themselves did not. That may be because eating the grains gives the full complement of the microbial community that constitute the "grains"? Just a speculation.
