I read somewhere on here (can't find it now) that some have experienced that it takes longer for bigger bottles to carb. The theory makes sense to me. That said, is there a general rule on length of time for bigger bottle? I would assume that it is not a linear relationship with bottle volume. I ask because I started this thread (https://www.homebrewtalk.com/f35/high-gravity-carbonation-issue-356459/) on a high gravity carbonation issue I'm having, my plan is to do nothing except wait a couple months before tasting again. The batch was bottled in 22oz bottles except for 2x 12oz (to test for carbonation). I now only have 1x 12oz left. If the 12oz is carb'd at Thanksgiving to my liking, is there a rule of thumb for how much longer before the 22oz's are the equivalent?
