Looking forward to brewing this soon so it will be ready for the holidays!
Anyone else get higher OG and IBU numbers when plugging this in to their software? With Brewer's Friend I'm getting OG of 1.083 and IBU of 47. Usually when I enter a recipe from HBT into BF I'm within a point or two for both.
I searched this thread and someone mentioned a similar issue with BeerSmith, but it looks like no one ever responded to that. I also noticed that when someone converted this to 10 gallons, they actually had 11 going into fermentor. Is the grain bill meant for a 5.5 gallon batch rather than 5?
If the numbers in my software are correct, the finished beer will be about 9%.
Thanks!
The efficiency of the original post was 75% so maybe you have a higher value?
Also depending on the software you are using and how you set it up you could be using a different IBU calculator than the original poster.
Normally either Tinseth or Rager.
Generally Rager attribute more IBUs to the bittering hops than Tinseth and it's the other way around for the additions in the last 30 mins i.e. Rager attributes more IBUs to the flavour aroma additions, relative to Tinseth.
Since the ratio of bitter hops to aroma/flavour is 1:1 and you are getting more IBUs I would guess that the OP was using Tinseth and that you were using Rager but it's all just guess work
Edited to add:
I also forgot the obvious one - did you adjust weight to match the alpha acid % of the OP?
If your hops have a higher value then you will get more IBUs and need to use less to get the same value.
