I'm pretty new at this but have learned more than I should be reading too much!
I understand that your boil volume effects the hop utilization; more boil volume = more IBU's from the same hop quantity.
My question is about "Average Boil Volume".
Lets say my recipe calls for an average boil volume of 3.5 gallons (Partial boil) in order to give me 37 IBU's. Does this mean I should start the boil with 3.5 gallons or does this mean that over the entire 60 min boil I should average 3.5 gallons? If it means the latter then I would need to start with around 4.0 gallons so that I have around 3.0 gallons left at flame out due to evaporation loss so that I average 3.5 gal.
??
Just need clarification. I don't want my IBU's to be messed up because I don't understand what the calculators are asking for with "Average Boil Volume".
