Well I proposed the terminal at 1.022 and yes it is still dropping, very slowly.You say it's 10 gravity points away from terminal. How do you know what the terminal gravity is?The question is, is it still fermenting? Is the gravity still dropping?

umm I would say in the beginning it was about 10 points a week but now its slowed to less than that. 5 weeks in primary won't produce any off flavors?...and by that I mean autolysis.How slowly is "very" , point per week? point per day?

Good pitching rate? Yeast health? What yeast? Good aeration/oxygenation?Transfer lots of trub (hot break/cold break, hop shit) to the primary fermenter?umm I would say in the beginning it was about 10 points a week but now its slowed to less than that. 5 weeks in primary won't produce any off flavors?...and by that I mean autolysis.

Autolysis due to alcohol %? According to my calculation you are at 8.1% alcohol and a Doppel by style ranges up to 10% The alcohol % right now won't produce that at least I say yeast are more tolerant than that. I think you are fine to leave it at the temp you got it going. If you don't see a drop over 2-3 days then it could be done fermenting. In addition your attenuation % is around 63.1% and I would think that there are still some % to ferment up to as well or at least left in your yeast. What yeast are you using? If your Pils is just getting started why don't you leave your Doppel in there with it till you dont see a change then remove it from your fermentation chamber and place it in a ice bath and let it warm up. A lot of times when you are 75% done with fermenting a lager you can warm it up and that will help it finish to FG as well. I agree with Slainte on knowing your FG, I guess you caclulated your FG based on attenuation but hey let it go till its done unless you get really low but at 1.033 I would guess it will be just fine as well.umm I would say in the beginning it was about 10 points a week but now its slowed to less than that. 5 weeks in primary won't produce any off flavors?...and by that I mean autolysis.

If you pitched a suitably large quantity of clean, healthy yeast, and your sanitation is good, then I wouldn't worry about going 6+ weeks in primary. Especially for a lager this big. Let it finish.In my opinion, autolysis is far less of a concern at the homebrew scale (assuming proper yeast handling/pitching proceedures) due to the much lower pressure the yeast is under as a result of the mass of the beer above it.5 weeks in primary won't produce any off flavors?...and by that I mean autolysis.
