Autolysis isn't like El Chupacabra. It does exist. But on the list of all the things that can go wrong with a beer, autolysis one of the rarest.
My point was when I did primary only, my beer was drinkable at 6 weeks in the bottle but not enjoyable until 8 or 9 weeks.
When I switched to a secondary, which I do more for conditioning than anything else, my beer is enjoyable after 2 weeks in the secondary and 4 weeks in the bottle.
Is a secondary necessary? For most ales, no. But it gets me to drinking faster.
Side effects may include: not feeling your face when you're with me. If facial numbness continues for more than four hours, it could be a sign of a serious medical condition. Seek immediate medical help.
