Inconsistent results with kefir

[Guest guest]

Lately we've been having very inconsistent results with our kefir-making. We

got our

" grains " from a local WAPF member and they worked just fine for several months.

However,

recently the kefir has been watery and lumpy, and tastes somewhat " off " .

Nothing has

changed in our production methods. We add raw milk to the grains along with a

little bit of

kefir from the latest batch and let sit for 24 hours or so depending on the

temperature. The

last few batches have not been good at all.

Is it possible something happened to the cultures? I can't imagine what, but it

definitely

seems they aren't " doing their thing " . Has anyone else experienced something

like this?

What did you do?

I suppose one solution would be to get some more grains.
