Double Trouble is good stuff. Wouldn't guess 9.4abv.
Trying to put my finger on the hops - thinking centennial, cascade and maybe willamette?
It's got a bit of a floral character in there that I really like. Good pick!
Email straight from the brewer a few years ago via thread on homebrew talk:
20plato OG and the hopping is use Summit for bittering and a blend of Simcoe and Amarillo for flavor, finish and dry-hop. On my Pro-Mash recipe software I target 180 IBUs, but in reality I only extract probably half of that. Ferment it with an American yeast and dry hop it with at least a half ounce per gallon towards the end of primary fermentation.
Definite pineapple and tangerine so it makes sense.
