Does this procedure make sense when adjusting IBUs on a late addition extract boil?
Since the extract is added in the last 15 minutes, it will have no effect on the bittering hops. Therefore the IBU values calculated by Promash are too low.
If after the batch OG is set, Changing the SG value of the late addition extract(s) to 1.000 should give the true sg that the bittering hops are being boiled in. One can then adjust the hops more accurately.
Thanks in advance for the input.
