The blowoff had stopped as of this morning, but fermentation was still going hard. The worst part is loses of just over 1/2 gallon of beer. At the peak of fermentation (when the picture was taken) the stream of co2 out of the blowoff tube alternated between a continuous stream and bubbles 4-5 times per second. One of the worst things for a barleywine is under attenuation IMO, I shouldn't have that problem. My basement is 62/63F which has kept the temperature in a reasonable range during the peak of fermentation 70-72F. Once things slow more I will move the beer to a spot in the upper 60s to ensure complete fermentation and allow for it to cleanup any by-products generated during the peak of fermentation and finally dry hop it.
