I've never actually had this multi-award winning beer, but I see that Northern Brewer has brought back their clone called "The Innkeeper". Seeing how the grain bill is nothing more than Golden Promise and a dash of Extra Dark Crystal, I put together an all grain recipe over on Brewmasters Warehouse.
It's only a half batch (since I'm stove top brewing and bottling multiple half batches this winter), but doubling it wouldn't affect the price much.
As I said in the recipe notes, you need to add .5lbs of corn sugar @ 60 minutes (for the half batch, that is. A full batch would need a full pound @ 60 minutes). I didn't include in the brew builder since they only have 4 pound bags for $7 and change, and I can normally pick up pound bags at my local brew shop for about a buck.
