Hey Denny - great topic! Recently a friend and I brewed an attempt at a Sierra Nevada Torpedo-like IPA. I brewed 10 gal. and split the batch to experiment dry hopping with some of the newer varieties on half of the batch. Keeping with the Torpedo theme, they were named Warhead and Peacehead IPA.
The grain bill was:
4% Crystal 60
Target OG 1.069 / IBU 69. Mash at 152.
The kettle hops were:
Magnum, 56 IBU, 60 min.
Crystal, 4.5 IBU, 20 min.
Crystal, 1.5 IBU, 5 min.
Magnum, 4.5 IBU, 5 min.
Crystal, 1 oz., Hopstand at 170 deg. for 20 min.
Magnum, 1 oz., Hopstand at 170 deg. for 20 min.
Citra, 1 oz., Hopstand at 170 deg. for 20 min.
Warhead was dry hopped for 5 days with 1 oz. each of Citra, Crystal and Magnum
Peacehead was dry hopped for 5 days with 1 oz. Meridian, 1 oz. Mosaic and 2 oz. Simcoe
Warhead came out similar to Torpedo in flavor (balanced hop/malt and restrained sweetness) and Citra aroma came shining through. Peacehead aroma reminded me of Hill Farmstead S&S#5 with citrus, grapefruit, some tartness. Flavor was fantastic and hop bitterness danced on the tongue.
We had a club taste-off for NHC first round entry fees and Peacehead won the IPAs, but alas did not advance past the first round. Will try again next year!
I have also used the Meridian/Mosaic dry hop combo on an IPL (all Hallertau kettle hops) that our club served at club night, which was a big hit.
