Brooklyn Black Ops does not exist. However, if it did exist, it would be a strong stout concocted by the Brooklyn brewing team under cover of secrecy and hidden from everyone else at the brewery. The myth is that this supposed “Black Ops” was then aged for months in bourbon barrels, bottled flat, and re-fermented with Champagne yeast. Presumably such a beer would raise a rich, fluffy dark brown head and it would combine chocolate and coffee flavors with a rich underpinning of vanilla-like bourbon notes.
