Cold Crash & Bottling Temperatures

[thomer]

I am in the process of my first cold crash of a Lagunitas IPA clone.
Once finished should I return the carboy to room temp before bottling?
Or will that release some of the 'gunk' back into the beer?
I am just thinking that as the volume reduces during freezing, it must expand when the temperature rises.
So bottling at that temp (36f) might help to produce bottle bombs.
Or am I overthinking it.

What are you fermenting in? Do you have a way to prevent suck back or oxygen ingress?

I am using a carboy. I have a 6ft blow off tube into Starsan. Sucked Starsan up to about 3ft of the tube, so oxygen ingress.

You won't have any issue bottling at those cold temperatures. There won't be any significant change in the volume. If you use a priming calculator it will typically ask for the temperature of the beer. Don't use the current temperature but rather the temperature it finished fermenting at, otherwise you risk under priming your bottles.

Ok, so you can bottle at the cooler temp, if you're priming the whole batch make sure you get your priming sugar mixed in well. And as mentioned above I would use a priming calculator.

Bottling cold is not a problem, but you will need to let the bottles warm up to 65-75F so the yeast can carbonate them. So it doesn't really matter if you warm the beer in the carboy or the bottles.

The little bit of air you leave at the top of the bottle serves as a cushion against thermal expansion of the liquid.
