42 degree primary oops

[jcac27]

Well I messed up. I unplugged my small fermentation fridge while primarying a quad and plugged it back in to the heating side of my controller by accident and this morning my beer is at 42 degrees. Obviously I unplugged it and opened the door and am trying to get it back up to room temperature. Any suggestions to get the yeast active again? Stir it up?

You could swirl your ferementor to kick the trub up again but I'd bet just getting it back up in the 65F range will get it chugging away again. Yeast are amazing things!

You will be fine!

Thanks for the reassurance. Sg already at 1.023 from og of 1.097 so it's close to done anyway just hoping it finishes up. It's back up in the high 60s and I shook the bucket a few times. No bubbles in the airlock yet. I pitched a pretty big starter so hopefully there's enough viable yeast left.

Bringing the temp down to 42 isn't going to kill the yeast, just make them really slow down. Bringing the temp back up is enough in itself but as mentioned swirling the fermenter to get the yeast back into suspension can sure help them along. So yeah, you'll be fine.

We have bubbles. Hopefully it finishes. Thanks for the reassurance

It should! Keep in mind that yeast is usually stored in a refrigerator before you pitch it, so now that it's getting back up to the temperature that it like to ferment at, it's getting to work.
