I brewed a 5 gallon batch and strained it into my primary, a 6.5 gallon carboy. I realize that all thead headspace air, was quickly displaced with my yeast going crazy. The foam did rise quite a bit, but because of the large headspace it never actually made it into the blow off tube and out. So now it's sinking back down into my brew. Should I care? tomorrow will be a week that it's been in the primary, so things should be about done.
I've got a few options I suppose.
a) leave it and let if finish and set
b)move it to a secondary hopefully leaving the cake at the bottom and the foam film on the top so that it can rest
C) next time use an actual 5 gallon carboy so the blowoff actually all makes it out of the blowoff tube.
