After listening to the Jamil Show on Oatmeal Stouts, I've decided to give Jamil's recipe a shot. I entered it into BeerSmith and noticed my IBU level is very low (28 IBU) compared to what it "should" be (36 IBU). Here is the recipe:
Batch Size: 6.00 gal
Boil Size: 8.71 gal
Boil Time: 90 min
Equipment: Brew Pot (7.5 gal) and Igloo Cooler (10 Gal)
Ingredients
Amount Item Type % or IBU
9 lbs 6.4 oz Pale Malt (2 Row) UK (3.0 SRM) Grain 72.87 %
1 lbs Oats, Flaked (2.0 SRM) Grain 7.75 %
12.0 oz Chocolate Malt (350.0 SRM) Grain 5.81 %
12.0 oz Victory Malt (28.0 SRM) Grain 5.81 %
8.0 oz Caramel/Crystal Malt - 80L (80.0 SRM) Grain 3.88 %
8.0 oz Roasted Barley (500.0 SRM) Grain 3.88 %
1.80 oz Goldings, East Kent [5.00 %] (60 min) Hops 28.1 IBU
1 Pkgs English Ale (White Labs #WLP002) Yeast-Ale
Beer Profile
Est Original Gravity: 1.055 SG
Est Final Gravity: 1.018 SG
Estimated Alcohol by Vol: 4.81 %
Actual Alcohol by Vol: 5.08 %
Bitterness: 28.1 IBU
Est Color: 35.3 SRM
I know Jamil uses ProMash and there's usually some variance, but the difference is huge and I can't figure out why. I don't want to over hop this beer because my BeerSmith measurements were way off. Any thoughts?
