I have the attached recipe and the IBU calculation is confusing me.. why do the itemised IBU values (21.3) not add up to the total IBU value (49.1)?
This is likely something to do with that fact this is a partial boil and/or the majority of the extract is a late addition.. am I doing something wrong here?
