So, everybody says, "don't leave a beer sitting in the primary fermenter for longer than 2-3 weeks" because you may subject yourself to autolysis.
For my last lager, I couldn't bring myself to throw out all that nice yeast sludge (Saflager 34/70), only to brew another lager and have to pitch 2 new sachets on it. Surely the yeast cake left from the previous lager would be like a "super starter". So I pitched my latest lager on the yeast cake and it went like a dream, tastes great out of the fermenter etc etc. I now have a bock that I want to ferment. Its obviously high gravity, so a good dose of yeast is preferred. At this stage I am going to pitch the bock on the yeast cake, which will make it the third brew in a row on that yeast.
Am I subjecting myself to autolysis by doing this? Is what I am doing sort of like leaving a beer sitting in primary for 6 weeks (3 brews X 2 weeks each)?
How many times can you safely pitch a new brew on the yeast cake of an old one?
