Wow, I set up my first blow off tube yesterday after pitching my high gravity ale with a 3 step starter (approx. 700B). I read numerous times how people learn the hard way and for once, I learned from their hard way! Boy am I glad!!! I had to double wrap wire over the bung to hold this thing down! Not every brew "blows off", anyone ever find a correlation between pitch rates, styles, etc? No doubt, always better safe than sorry, but no harm in a discussion!
