Ok, back on August 19th I brewed up a batch of AHS pumpkin ale (using extract and windsor ale dry yeast) I let it sit in the primary for 4 weeks then I moved it to a carboy to clear it up a little. Its been clearing for about 2 weeks when tonight I noticed that the air lock was bubbling. The beer looks totally clean but it looks like is carbonated. I see a constant stream of bubbles rising. Now the only thing that has changed the last few days is that its gotten colder in the house. Is is really starting to ferment again???? - its a little late now but I'll move it to an empty keg tomorrow morning. Just tryign to figure out what's happening.
