Attempting to follow a recipe but hops I have have higher AAs

[Lord Callahad]

HI

this is probably a simple one to answer. i'm making a recipe which has a load of citra (11% AA) hops - its the zombie dust clone extract recipe. the citra i got are all 14.7% AA. i've calculated that as a 33.6% rise and reduced the same in weight of all my hop additions. the IBU seems to be roughly the same. is that how you do things or am I missing something? (p.s. I am aware IBUs don't really equate to taste and there's far too many other variables at play, but it was just bugging me i guess!) thanks

Simple proportions. Divide actual by target ans multiply by the initial amount.

That is pretty much what I do, when I remember to actually note what the AA is. I have a bad habit of not actually paying attention to the recipe vs what I have on hand.

The BF software does an excellent job of calculating this for you. Just enter the boil time and the AA of the hops. If the IBU is too low or too high, simply adjust the hops amount.
