Whenever I run up a recipe from the data base my IBU's are always off. Can somebody have a look at this and give me an opinion of why I am getting 32.1 IBU instead of what Ross has posted as ending up with 36.6?
I usually run up the author's original and then tweak the hops to end up with the same IBU's per addition with the pellets and AA% I actually have in stock if this makes sense.
I have added the NS as Bittering/Leaf with an Alpha of 11.4% and a Beta of 3% and hop use Boil if this helps.
Any ideas gurus?
Cheers
