What is considered the "standard" length of time for cold crashing?
I usually do it for three or four days, but is that too little or too much?
I don't think that it's a huge deal either way, but I've been crash cooling overnight, adding gelatin in the morning and waiting about 36 hours and racking to a keg. I've been getting commercial looking beer, for what that matter?
It is temperature dependent...A day or two at 30 degrees and you will be gtg
double post...got screwed up sorry
Good point, I do drop it to just below freezing
Is it possible to cold crash for too long?
Yes. You start having to call it lagering or cold conditioning after about a week.
