Well, I emailed Bell's for some insight....They did me a solid with some nice information.This was their reply....
Hi Frank. Sorry for the delay getting back to you on this. Here’s what I can tell you: the mix of coffee comes from Water Street Coffee, but is pretty tight lipped. I would make at least part of the blend a pretty aggressive flavored coffee. I would crush the beans and add around ½ lb. to a 5 gallon batch after primary fermentation subsides (maybe in a secondary).
As far as the recipe goes, I’d put together a nice stout with plenty of chocolate malt, maybe half of that amount roasted barley, and about half that amount black malt. Give it some good body with some munich and flaked malts as well as a bit of medium crystal (60L ish). Shoot for a gravity of 1.075 or so. Hops are just enough to balance sweetness. Something neutral. A neutral yeast as well.
I hope that helps.
