It might work in that scenario but I actually want to boil off over 6 gallons(so I don't want to adjust my boil off), and maybe that is what is not allowing me to do it.
Ya I can probably manipulate the system to give me what I want out of it, but should I have too? Is it unreasonable to want to do a long boil?
I boil off 1.2 gallon an hour. And this will be a 6 gallon batch. And I want to boil off that much for a 15% beer...or at least that's what I'm shooting for.
