Im brewing a clone of fresh squeezed ipa. I want to ad gelatin finings to my beer but not sure when to add. I was just going to do a 3-4 week primary dry hopping the last 7 days, then bottling. When do i add the gelatin? 3-4 days before bottling? or at bottling? Will it effect dry hopping? Do i need to gently stir ti mix it in being careful to not introduce anymore oxygen? Or should i do a secondary?
