That's actually a different beer, I think, not a BCS variant. Night Stalker's only 11.2% ABV and is all Simcoe and Mt Hood. Bourbon County (both regular and coffee) are 13% ABV and all-Willamette.
I could be wrong, though, maybe they changed up the recipes.
I had to check on this, as my memory is notoriously buggy, but this (below) was pulled from an old ad on the GI website. The barrel aging may up the ABV - that's my guess. Whatever its relation to the other GI RISs, they're all super delicious.
Night Stalker is an American television series that aired on ABC in 1974. It featured a newspaper reporter Carl Kolchak, played by Darren McGavin who investigates crimes with mysterious and unlikely causes that the proper authorities wont accept or pursue. The series version was set in Chicago and is credited as an inspiration for the X Files.
Goose Island Beer Company will release its third beer in the Fulton Wood Series, Night Stalker, as an homage to the Chicago-based television show. Night Stalker is a jet black, dry hopped Imperial Stout, extremely rich and full flavored with malt and chocolate followed by a bright dry hopped aroma. It is the same base as our Bourbon County Stout, but instead of aging in Bourbon barrels, we dry hop it like madmen.
