I am finalizing my recipe for my brewday today and I am going to do my first attempt at first wort hopping.
This will be an IPA, full boil, 7.24 gallons for a 5.25 gallon batch.
Grain Bill
10 lbs 2-Row
1 lb Biscuit
1 lb Caramel/Crystal 60
* I have DME available incase my efficiency is low
Hop additions
1.00 oz Citra FWH 60 min boil (30 min sparge) - 48.8 IBU (13.9 AAU)
.5 oz Citra 15 min boil - 10.3 IBU (13.9 AAU)
.5 oz Citra 10 min boil - 3.8 IBU (13.9 AAU)
.5 oz Citra 5 min boil - 2.1 IBU (13.9 AAU)
.5 oz Citra 1 min boil - .9 IBU (13.9 AAU)
This gives me 65.8 IBU on Beersmith where I am using the 60 Min Boil and First Wort Hop calculation. I have the input set at 90 to account for my sparge? Is this an accurate AAU calculation for First Wort Hopping?
I know there is a lot of debate on FWHing calculations to either put them in as I did or input them as a 20 minute boil. When I enter them as a 20 minute boil my IBU's go down to 42.1.
Which calculation should I use or should I just skip the FWH altogether?
