I leave it as is and just be careful when draining off the beer such that the yeast head stays in the bucket

So in summary - what you've got there is "normal" for me.
Generally Safale 04, and Harvey's brewery yeast once. The one occaision I recall when the head didn't last long was with a Brupaks kit, but I fermented at too high a temp - head was frothy for a couple of days, then gone. I tend to barrel after 6-7 days though, and don't touch krausen at all, which may explain why it remains.DaaB wrote:
