I knew up front that the 1007 builds a monster krausen. Between that and using my new stir plate and O2 system for the first time, I knew that I'd better watch things like a hawk! All is good so far, and blow-off seems to be letting up after 48 hr. Hopefully I'll be doing my final airlock swap in a couple hours. Edit: I also got a very clean transfer out of my boil kettle, so I don't have any chunks coming through to plug things up.
