Hi!
I'm experimenting with not boiling the hops and instead just do at hot steep/Whirlpool or a mix of both. Since I have an insulated kettle (which also has an insulated lid) the temperature of the hop stand can be kept high (near boiling temp) for a very long time if I want a high IBU contribution from the steep. To get the IBU numbers from a hot steep to be consistent with the perceived bitterness I had to tweak the “Steep/Whirlpool Util Factor”. I thought that this setting only should affect the hop I choose to be steep/whirlpool hop and the late boil hop additions which also will be steeped. But … if I for example set the Steep/Whirlpool Util Factor to 100% I noticed that all hop additions get almost the same IBU contribution even if/when no hops was assigned to be steep/whirlpool hop.
It means that when I’m not want to do a steep/whirlpool but just do traditional boil hop additions and a fast chill, I get very strange (I guess incorrect) calculated numbers for the IBU. For example a 5 min or even a 0 min/flame out addition gives almost the same numbers/IBU contribution as a 60 min. It does not seem logical, does it?
Is there any thought behind this behavior that I don’t understand or is it just a bug that can be fixed fast and easy?
