IBU calculator

[farmer brown]

Me again!

Im a little confused about the IBU calculator above, surely the boil time will influence the final IBU? Would anybody know what to put in the Estimated Utilization for a 60 minute and 90 minute boil?

a recipe forulator like either beersmith or eer engine will work out ibu for you. If you search the forum you will find a few ibu calculators from before
