Well they don't give much away on their site. From reviews it does sound pretty malty/caramel-y and on the sweet side for a DIPA, and a hop bomb with lots of pine, resin, citrusy flavors. I couldn't find much on a quick search, there's this
thread from a few yrs back but no recipe info, unless you want to try to email the brewers.
Sounds like you may have some inside info though with the munich, do you know if those are the 3 hops they use or did you just pick those? If it's just a shot in the dark I'd probably try some simcoe or chinook for the pine, maybe pair one of those with the apollo and cascade. And use lots - i.e. for 5 gallons something like an oz of hops at 15, 10, 5, couple oz at flameout, and 2-3 oz dryhop. Who knows with the malt bill, but going with the minimal info I'd maybe try 20% munich, 5-6% crystal 40, and the rest some type of pale malt base (not really to my style for this kind of beer but trying to aim for what is described). I don't know about using an English yeast, unless you think that's what they use. I'd personally go with a chico strain or other American yeast.
