I'm still working on my philosophy. But, I'm thinking that I'm going to drop 15 min additions, and just do 60 and then 10 minutes on down. I've never done FWH. I think a big dry hop is vital for aroma and flavor in an IPA. I brewed with this hop schedule a couple weeks ago, can't wait to taste it.
1 oz Columbus, 1 oz Nugget @ 60
.5 oz Columbus @ 15
1 oz Casacade @ 10
1 oz Columbus @ 5
1.5 oz Columbus and 1 oz Cascade @ Flame-out (Steep 20 minutes)
2 oz Dry Hop Columbus 12 days
2 oz Dry Hop Cascade 12 days
I've found that my IPAs lack the bitterness I want, so I went hard with the 60 min. Beersmith will be calculating 100 IBU, and I'm saying "No way," when I drink the final beers. Maybe it's because I'm using a nylon bag, maybe my boil isn't vigorous enough. Next IPA all hops are just going right into the boil and the boil shall be strong.
