Yes, I understand. And, I went back and looked at section D, the hop bill, and saw I didn't need to reenter the info except for the AA%.
Rick wrote:Also, original recipe on HBT states 65 IBU according to the brewers calculations. The BIABacus shows us a different value. It's more like 71.7IBU (tinseth) as originally written on HBT, so perhaps they are using Rager or Garetz. I am not familiar with those IBU variations. I see you entered 60 IBU, which is what 3 Floyd's lists the brew to be. BUT, we again do not know if they are specifying tinseth.
Ok, I'm kind of lost on this, I'm not sure I understand the difference between IBU, Tinseth, Rager, or Garetz, etc. My LHBS has their IBU set at 59.6. I don't know how I could get the most accurate IBU info. I wouldn't be upset just using what I have since I have it, unless you can point me in a direction saying it would be detrimental to the beer.
Rick wrote:The fact that there is a 15 minute hop addition (on HBT) prior to the FWH addition is throwing me off. I'm skeptical of that, as it is very unusual for hop additions to be out of order like that. Might be worth a question, this may be the reason that the IBU's don't match, provided they were intended to be tinseth in the first place.
I saw a post about this and it had something to do with perceived bitterness and FWH in BS2 calculations. Setting FWH as a 20 min addition in BS2 in perceived bitterness...as I remember off the top of my head.
Good stuff and thanks for the help,
