Hi,
I am planning of doing an APA brew with Centinennial and Citra hops, and I would be happy to get some comments on my hop bill. This is the hop bill I have in mind:
@60: Centinennial - 15 IBU
@15: Centinennial - 9 IBU
@10: Citra - 8 IBU
@5: Citra - 5 IBU
@1: Citra - 1 IBU
Total 38 IBU.
Then I will add more Citra during cooling and then dry hop with some more, however I am not sure how to calculate the IBU gain during flameout additions and dry hopping so I don't know how much to add. I want to arrive at 40 IBU.
Cheers!

Dry hopping adds very little IBUs, flameout additions really depend on how you chill and how long it takes to get under the 80C mark as the hops will continue to isomerize above that temp. Unfortunately the IBU values for these are pretty tricky to calculate. Do you have the BIABacus? Some folks put 5 mins in BIABacus for their flameout additions and find that calculation gets the IBUs pretty close (still depends on the above though). In the end, I'm not sure the average person can really tell the difference between 38 and 44 IBUs anyway... Looks like a tasty hop bill in any case!

Thank you for your reply. I'll try the 5 min trick in BIABacus. So then there must be an independent way of calculating/measuring IBU? How is that done?goulaigan wrote:Some folks put 5 mins in BIABacus for their flameout additions and find that calculation gets the IBUs pretty close (still depends on the above though).

Sounds like a pretty tasty brew. Keep good notes and continue to experiment with hop additions, you can create a completely different flavor profile simply by changing hop schedule and amount. Have fun!
