I have a pale ale that's been in the primary for three weeks and I'd like to cold crash it before bottling. I'm planning on packing a utility sink with frozen water bottles to do the job. So here's my dilemma: I am going to be out of town for the next four days, should I toss the fermenter in with the ice bath now and let it sit and eventually warm up over the weekend, or should i wait until i get back crash it for 24 hrs and bottle? Does it make a difference?
