I have been brewing since 07, I cold crashed for the first time with the honey brown I am doing right now. When I kegged it yesterday it did not seem any clearer than any other beer I have done but it was cold. The beer is in the fridge absorbing CO2 right now. I will know in a few days if it actually made any difference. If nothing else makes it faster to force carb it because I don't have to wait for it to cool down. I usually force carb all my beers and usually wait a day after kegging them to do anything other than purge the head space. I only cold crashed for 31 hours so that may make a difference. I will post back in a few days and let you know what my final results are.
