Fermenting and Lagering at the same time

[Blackdirt_cowboy]

I have a fermentation chamber where I'm currently lagering a dopplebock at 33°. I am dying to start another lager, but I don't have another chamber to ferment in. The doppelbock will have been lagering for 2 to 3 weeks before I can get around to brewing again. Would there be anything wrong with raising the temperature of my fermentation chamber, and thus the dopplebock to 52° for a week or two to ferment my next brew and then going back to 33° to finish the lagering the doppelbock? Will raising the temperature in the middle of lagering for a week or so be a detriment to the doppelbock?

I'd go for it, i don't think a couple of weeks above your lagering temperature will do anything dramatic like "reset" the lagering time already on the clock...

Cheers!

Or you could get another temp controller and a heat wrap. Keep the chamber at 33 with one controller, and the new beer at 52 with the second controller and heat wrap.

I built a cabinet on top my chest freezer. It has a cpu fan that pulls the cold air up and another fan that pushes the air down. Its on a separate temp controller I can keep my kegs cold in the bottom and even ferment lagers on the top. The cabinet is insulated and has a removable floor to get to the kegs

Here's a thread where I describe how to do that:

If I were going to do what JoeK says above, I might get some 1" insulation board and build a box around that fermenter to help insulate it from the colder temps lagering the first batch.
