I think that it also doesn't like really cold temperatures. It seems
to quit working when the temperature falls much below 50 degF. I
also probably managed to acclimate the yeast to a high temperature in
the first week of fermentation. (We had a real warm spell and I don't
have a beer fridge.) The temperature in my fermentataion shed went
into the mid 50s yesterday and the stuff is fermenting again. Another
batch--started two weeks later and thus missing the severe warm spell--
fermented fine at lower temperatures, but still couldn't deal well
BTW, I got a fine Pilsner using #2402. Fermentation and aging took
place at about 50. Attenuation was fine. It has a softer flavor
the the standard (P.U.), but I'd call this a difference rather than
a flaw. It is by far the current house favorite.
