Yes I did, and I am dissapointed - kegged 1/2 of it 3 days ago. I think I am going back to the Munich/CaraMunich rather than the Aromatic - maybe in combination. It doesn't seem as well balanced now. A lot more bittering comes forward and stays - beer's young, but the other 2 versions I did were better this young. Hopefully, the hopbittering issues were not as related to the substitution of some 2-row for some of the GP. Oh well, this is going to be a long project.

I may take this back to 5-gallon batches.
However, the increase in the hop schedule really works for the DH.

Summit is more of a tart taste to me, but YMMV. I think the Ahtanum, along with so many other hops is a bit subtle to add a lot to the boil. I think it gives more character to the DH.
That being said, I didn't use all of anyone else's advice either! Have a great brew!

Update: I just looked up Yoop's recipe. It actually is very similar to mine - Munich/Caraminich version - scale it. I see the Summit is for bittering - not an issue. I used Warrior. She added a bit of black for color. I may need to drop back to all Golden Promise

. It really dough-balls up; I was hoping to save a little effort by subbing some 2-row.
