I'm going to be brewing a Sweet Stout possibly this weekend, if not, next week for sure. I have researched threads on this and most say to reduce hops by about 20-25% or so due to higher hop utilization with lower gravities. I have begun doing late extract additons and using Beersmith for some calculations. Here is the recipe:
Type: Extract (Late Addition)
Batch Size: 5.00 gal
Boil Size: 3.00 gal
Boil Time: 60 min
Ingredients
Amount Item Type % or IBU
4.50 lb Amber Dry Extract (12.5 SRM) - Dry Extract 56.25 %
1.00 lb Wheat Dry Extract (8.0 SRM) - Dry Extract 12.50 %
1.00 lb Chocolate Malt (450.0 SRM) - Grain 12.50 %
0.75 lb Caramel/Crystal Malt - 60L (60.0 SRM) - Grain 9.38 %
0.75 lb Roasted Barley (300.0 SRM) - Grain 9.38 %
1.50 oz Fuggles [4.50 %] (60 min) - Hops 17.1 IBU
0.50 oz Goldings, East Kent [5.00 %] (15 min) - Hops 3.1 IBU
1.00 tsp Irish Moss (Boil 15.0 min) Misc
1 Pkgs Irish Ale (White Labs #WLP004) [Starter 1000 ml] Yeast-Ale
Beer Profile
Est Original Gravity: 1.050 SG
Est Final Gravity: 1.014 SG
Estimated Alcohol by Vol: 4.76 %
Bitterness: 36.3 IBU
Est Color: 46.0 SRM
According to Beersmith (Hops Bitterness Calcualtor), if I were to just steep my grains I would have a SG of 1.002 and if I were to add my bittering hops at the boil for 60 minutes that would give me 25.9 IBU's and with my last hop addition at 15 minutes that would give me another 6.5 IBU's. However, I will be adding all of my DME for the last 15 minutes of the boil, which will affect the gravity, reducing hop utilization. My Brew Sheet states that the Pre-Boil Estimated SG with all grains/extracts added is 1.084, though, all the DME will be added late (last 15 min).
Why would Beersmith calculate the Pre-Boil Estimated SG with all grains/extracts added when doing a "late addition"?
Why the difference between the Hop Bitternes Calculator on Beersmith (total=32.4 IBU's) and the actual recipe (total=36.3 IBU's)?
Will there be a significant difference in the total IBU's because of the higher gravity when adding all of the DME in the last 15 minutes?
I made sure to check the late extract additon in the recipe so I'm a little confused???
