Does anyone have a ballpark figure on the boiloff rate on a keggle over an hour?
Pol, quit being difficult.
I'm sure he's just trying to work out some standard calculations or plug that number into some brewing software. You can use a percentage, but it's got to be over a specified time period. I think 10-15% evap over 1 hr is pretty standard with a nice rolling boil.
The boil-off rate will be specific to your set-up. Develop some good measuring techniques and just do an experiment over a couple of brewing sessions. That way, you will know your specific boil-off rate.
I'm just looking for a starting point. Ive got a keggle and I'm gonna enter it into the equipment database in beersmith and just need somewhere to begin.
Untrue...
You will always boil off (within reason) the same amount per hour, as a constant. A % will change with volume. That is the whole story.
10% of 12 gallons is 1.2 gallons
10% of 6 gallons is .6 gallons
You dont boil off twice as much when you double your batch size.
