I’ve been given advice to bring my lager out of my 50 degree basement into the upstairs at about 65 degrees for 2 or 3 days for a diacetyl ‘rest’. I’m now wondering: Should I bring it back to a 50 degree fermentation temp, or just go to a 34 degree lagering phase? It’s only been about 24 hours, but the fermentation seems to have stopped. It got quite active for a few hours, but now I don’t see bubbling or anything.
Give it 2-3 weeks to finish primary before the d rest. After the d rest, I go straight to lagering.
It has been said that the d-rest should be done before FG is reached.
I don’t worry about it. I do more of a attenuation rest anyway. When it looks done I let it sit at room temp a day or two then get a reading and taste it. I’ve never had diacetyl in a lager. After that I crash it to lagering temp.
