I've done a few AG batches and my system is pretty sound. I am having trouble with on area though and I wanted to understand what you guys do.
I sparge into a graduated bucket to measure my pre-boil volume and I also have a somewhat calibrated stick that I can insert into the boil kettle to measure volume.
Once I hit my pre-boil volume, I stop sparging and start boiling. I know that I need to boil off a certain amount. My problem is that at 45 minutes, I stick my immersion chiller into the boil and it raises the liquid level. At 60 minutes I shut off the flame but I am unable to measure my post boil volume.
When I rack off into the carboy's, I am getting more wort than I expected. I have my evaporation rate in beer smith set to 12%.
Here is my questions
1. How do you measure pre and post boil volume
2. what evaporation rate do you use to calculate boil off?
