I'm brewing a Belgian Strong Dark (along the lines of a quad) and I pitched my yeast Friday night. By the next afternoon it had really started to get going. I have the carboy in my living room because that's most most consistent room temperature-wise at an even 68 degrees. I took some temperature readings of the beer itself and it was right around 70 degrees.
This morning I woke up and the beer is really going strong, but the temperature of the beer has climbed to 80 degrees! It is not near any heat source, but I do have the carboy wrapped in a blanket to keep the light out. The "optimal" temperature range of the WLP500 is 65-72, so I am worried this is going to give the beer off-flavors.
I think my best move is to remove the blanket and instead of keeping the carboy upstairs, move it to the basement into a dark closet which is around 60 degrees. I think the heat being generated by the beer will keep it warm enough in the lower temperatures and help balance it a bit better in the appropriate range. Any thoughts on this?
And secondly: if my final gravity is still high when this round of fermentation is completed, can I transfer to another carboy and pitch another round of the same yeast strain to try to get it lower?
