Don't know if this has been asked before - when doing first wort hopping do I use the 60 minute boil option? I know I can chose FWH but it still requires a time in boil value. Only reason I ask is because somebody said to change that to 20 min, which I don't believe is correct. The total IBUs plummet down in that case.
So many recipes...
