I have been one that always does a secondary to get my beer off the old yeast. Recently I have been doing a bit of research and there is a lot of opinion out there that the secondary isn't something that is as important for shorter fermentation times. My question is what is the max time that would be acceptable to keep the beer on the yeast in a primary to avoid a secondary. The general wording that I have found is for longer conditioning make sure to still use a secondary, but when does that point start?
