Hi! Does the IBU calculations take into account the evaporation rate of the equipment and the time of the addition? Let's say I add 10 grams of hops at 60 minutes. After 30 minutes, 1 liter has boiled off according to my settings, and I then add 10 new grams of hops, boiling for 30 new minutes. But then the volume has decreased, and the IBU calculations are off, unless the volume change is accounted for. Best regards, Simen Kvaal.
