Just made a falconer's flight/citra IPA. Well, for the first time, I have a free cooler to do a controlled temp fermentation. I had the cooler set to 50 degrees to help cool the wort before pitching. I pitched, and fell asleep before turning the cooler up to 63 degrees like a moron. I woke up to no action in the air lock and no movement in the beer. I got the temp up slowly (it took all day) and now it's in its controlled environment at 63 degrees. This morning i woke up there were a few tiny yeast rafts on top. My questions are:
1- Does the yeast rafts indicate the yeast waking up? Will fermentation kick off soon or am i out of luck?
2- The wort sat at around 50 degrees for 12 hours and has been slowly warming up for around 30 hours at the desired temp. Should i expect off flavors? Will it be alright since it was sealed and at a low temp?
