It fermented at 52F for a week when I brought it to 57F as I put 10G of Pils with 2278 in the chest freezer. It tasted great going in to the keg. I carbed it and let it sit until tonight. There was no identifiable off-flavor, kinda cidery but not really. Just bad. And if I poured it right down the middle, no head at all. Very strange....
