Recently started this process. Cold crashed 2 beers, then kegged with geletin.
In 11 years of brewing, these were the first 2 truely clear beers I've ever made.
I'm sold, and this will be standard practice from this point forward.... so... I guess what I'm saying to the OP is a big fat.... YES.
I set my temp controller to 35 degrees and left the beer in the freezer at that temp for 5 days. i then racked to keg with geletin.
From now on, I'm going to rack to secondary, add geletin, then cold crash in the carboy (secondary) for about 5 days. I'll then bottle or keg at that point.
