I was going to start a similar thread but I'll ask my question here. I use a 15 gallon ss pot and the boil off rate was completely different with my last 2 ten gallon batches. I started with 12 gallons with an imperial nut brown(assuming I'd lose 2 gallons in the boil) and ended up with a little over 11 gallons of beer. Just recently I did a pale ale and started with 11 gallons of water, this time I ended up with about 8.5 gallons of beer does the different styles of beer effect boil off rate? Both batches seemed to have the same vigorous rolling boil.
You didn't mention ambient humidity... is there a chance that played a role for you?
