AHS Bitterness ?

[JeffB]

Anybody know how AHS calculates the IBU in their recipes? Im miles off when I input the data into Beersmith.

Are you using the same boil volume?

...and same efficiency. I believe they assume 70%.

I don't know if they use Tinseth, Rager or Garetz. Choosing one or the other can swing it wildly.

 

[JeffB]

I put my efficiency at 71 and no Im not using their boil volumes but im only off by adding one half gallon. If I have BS set to read Garetz, it comes very close but throws off all my previous recipes. Im assuming they are using Garetz and my volumes could make the small difference up.

You can send Forrest a PM, I'm sure he can clear this up: http://iam.homebrewtalk.com/Austinhomebrew

We don't list IBUs anywhere that I know of. That would depend on whether you are making a full boil or partial boil, extract, mini-mash, all-grain, what meathod of all-grain, etc. I couldn't give an accurate IBU or SRM for that matter.
