Whirlpooling

It would be great if there was a way to input 'whirlpool hops' or steep hops.  I've heard the utilization ranging from 10-15% and also the utlization on any late boil hops would be impacted. 

Maybe there could be a feature to put in the length and temp of the whirlpool and then we could see a whirlpool IBU adjustment factor for the boil hops, in addition to seeing the IBU contribution of the hops added during the whirlpool?

Add a Hop.  In the "Use" drop down, select "AROMA".  Select a desired duration.  Granted, it does not add any IBUs.

Then you can add the "$STEEP_HOPS" tag to your brew steps report, if it isn't already there. 

See page 4 of the attached brewsheet for how it looks in a report.
