The Grainfather IBU calculator doesn’t currently compensate for boil temperature or hopstand temperature. It would be helpful and relatively simple for these IBU calculations to compensate for the temperature of the wort, by either specifying boil or hopstand temperature with the time at temperature.

Hi Samual, many thanks for the suggestion and feedback. We have added this to our NPD process for evaluation as part of our product roadmap.
Many Thanks
This is really important. If you Aroma Steep at 75C to 79C you do not get anything like the bitterness that Grainfather calculates in Hop Stand. Thus, most of my recipes show a totally incorrect IBU (much higher than actual)!
