I am working on building an APA extract recipe and was tinkering with the IBU's. Then I noticed my equipment profile was not set, and when I changed it the IBU's jumped from 74 to 89.
The only difference in the equipment profile was the amount of boil volume & top up water (added to fermenter), so i'm not sure why it changed at all. The initial setting was 5.7 Boil volume & 0 Top up, and the setting I changed to was 4.14 Boil volume & 1.5 Top up water.
I use the second option due to kettle size, and then add water to the ferementer to bring up to 5 gallons and then mix vigorously.
Does boiling the full volume really make a difference in IBU's?
