It's a sure fire way of guaranteeing that you will get one.
Like I've never
broken a carboy (until last week), and I've never
had a blow off in a 6.5g carboy (until a couple of months ago, when I got two back to back). I also always
get 85% efficiency, until today, when it suddenly dropped to 72%. Time to check the refractometer and thermometer.
