Fermentation Temperature too low??

[dannyl]

I'm new to brewing and this is the first batch i've done. I'm brewing an IPA (using the bell's brewery ingredient kit) and everything went really well. The whole brew day went perfect, I siphoned the wort into the primary fermenter and sealed it off at room temperature (around 65 degrees F). Unfortunately, last night (maybe 5 hours after I had sealed the fermenter) my heat died and when I woke up in the middle of the night my house temperature read 42 degrees F.

Is this going to kill the yeast? Can I pitch another yeast packet?

You didn't kill the yeast, they will wake up when it get back up to the proper Temp.

That will not kill the yeast, merely make them sleepy. You need to get down to 30-32F before they start to have issues coming back to life.

Just warm it back up into the 60's and it should pick right back up. Might have to gently rouse them back into suspension, but I doubt it.

Okay. Thanks for the help!

I'm wondering why you siphoned into the fermenter.. I think dumping it right in and splashing it around as much as possible (Only at this stage of the brewing process) would be better, in order to aerate the wort before pitching. Were you maybe tying to avoid getting hot/cold break or hop gunk into the fermenter? Some of that stuff is actually food for the yeast and won't do much harm to the beer

It what the kits tell you to do. We all know how well their instruction are.
