Well, still interested in making this clone. I sent an email to New Belgium in hopes of getting some information back to help. My request was sent over to one of the assistant brewmasters. The reply was that much of that info in confidential but here is what he could give me.
The malt bill is Pale, Munich, Caramel (80), and Chocolate malt. Hops are Target, Willamette and Liberty. The 2 step mash takes about an hour. The starting Plato is 17. Sugar is added to the boil. The most important part, of course is the yeast. Our founder acquired ours in Belgium many years ago but you can get pretty close to a flavor match with White Labs WL 500 from a homebrew shop.
A couple of concerns. One is that he only lists 4 grains when the website says 6. Can any of you give some educated guess about the other two? Aromatic & Biscuit?
I have never done a two step mash before but also read an interview with the head brew master in that the majority of their beers are done as a single mash @ 68C. Would a single temp mash still work? What would the concerns doing it this way?
Here is the recipe I came up with. Your comments and criticism would be appreciated.
