Nope, didn't leave anything in the kettle. May have boiled a bit vigorously but not anything more than I have in the past. It was cool with a low dew point and humidity outside.
I'm going to start watching boil-off a little closer the next few batches, adjusting as necessary with boil rate, time, etc. Had I cut the boil off short of 60 minutes in this case once I hit 1.045 or so, would I expect any issues with not boiling the full 60 as typically recommended? Is boil time more important than the targeted S.G. or vice-versa?
Question using the calculator you pointed me to: until I make the move to all grain, is there an efficiency that should be "dialed in" for extract w/grain brews?
