So, Brewtoad doesn't add any IBUs for whirlpool additions.
I made a 2.5gal sessionable SMaSH with Calypso (12.9% AA) with the following hop schedule:
0.25oz at 60
0.25oz at 15
0.25oz at 5
1.5oz whirlpool (15min at 170F)
According to Brewtoad, the estimated IBU was ~43. After 7 days fermenting, it tastes more like 100. Lo and behold, I put the same recipe into Brewer's Friend and got 108, since it assumes 10% utilization from whirlpool hops.
I should note I also gently squeezed the hops that I filtered out transferring to the fermenter.
So, is this just a (known?) shortcoming in Brewtoad, a combination of that and the fact that I squeezed the hops, or something else making it super duper hoppy?
I admit my knowledge of hop utilization from whirlpool additions is basically zero, so I have no real reason to trust Brewtoad over Brewer's Friend (or vice versa) beyond my tastebuds telling me that this beer is waaaaay too bitter.
In the interest of science, I'm brewing a second batch tomorrow (with Idaho 7, instead of Calypso—12.8% vs. 12.9%) and planning to use this hop schedule:
0.25oz at 20
0.25oz at 5
0.70oz whirlpool (15min at 170F)
Brewer's Friend tells me this is ~47 IBU, which is more like what I'm looking for. Is this a good way to go?
