I'm making a kolsch. I had it at 58ish for 6 days... The bubbling stopped completely. I brought it up to 65-72 ish for a diacetyl rest, and it started bubbling again............,, and has been bubbling for 6 days!!!! I want to cold crash it already for kegging. Should I wait til it's done bubbling? What would happen if I crash it at this point?
