If anything, with such a big beer like that, it's quite possible the yeast in primary were still working and needed to stay. Probably should have taken a gravity reading before transferring to the secondary. Live and learn, right?
oh, i see. Normally you should take a gravity reading prior to moving your beer from the fermenter to the keg. That way you can make sure it is done fermenting. How long did you leave it in the fermenter before moving to the keg? Good luck.
My understanding is that if you have removed all the O2, they can stay in a freezer for years. Jamil just talked about it on one of the most recent episodes of brew strong
