Good question on the Rager calculation.
The Can You Brew it recipe for Dead Guy Ale used Rager to get the hop profile on-target.
For example, in Rager, this recipe with 3.60 oz of hops is 60 IBU, exactly what Rogue states as the IBU profile.
Conversely, the same 3.60 oz of hops in Tinseth is 42.5 or 18 IBU less. To get to the same IBU in Tinseth, the hops increase to 4.50 oz or nearly an additional ounce more. That 4.50 oz in Rager is 85 IBU. Very confusing ...
I need to come in at 60 IBU. How would you calculate it considering there's a difference based on which forumla you choose.
Am I missing something?
The IBU quotes on Rogue's website, would they be Rager or Tinseth?
