I just brewed my 5th batch, but for the first time didn't use a kit, but an online recipe. So now, I have no idea of how long to keep it in the fermenter before bottling. From what I understand, a higher OG beer needs more time to age, but how much more? Is there some simple rule of thumb, or formula?
In case it matters, I made a Great Divide Yeti Imperial Stout Clone. I made it with extract, and missed the OG by a lot. The reading was 1.072 instead of the expected 1.090. I made another beer which had the same OG, and did 1 month primary, 2 months secondary and 3 weeks in bottles. That worked quite well, so I am inclined to stick to the same timeline.
