I'm adjusting Orfy's Old Speckled Hen recipe for my batch size and hops. I put it in to Beer Smith and it spat out an IBU of 69. I'm expecting bitterness of around IBU 47 based on the original recipe. The IBU total in the ingredients below add up to 48. Anyone know why the IBU is calculated as 69 ?
