A cocktails of this name appeared in the series Black Mirror. The episode was Hotel Reverie. In the series the cocktail appears clear and a poison was added.
As far as the real Black Rose presented here I think it is excellent.
Excellent, this one really surprised me. The Cognac and Grenadine create an almost cherry like sweet/tart combo that is perfect when paired against the Bourbon. Don't skimp the Peychaud's - it is essential to that underlying sweetness. This is an underrated classic, IMO.
A nice combination that starts with the oakiness from the Bourbon and finishes with the fruitiness of the Cognac. Used a very chilled Gibraltar rocks glass.
I tend to drink my drinks a little too fast. I'm a firm believer in "a warm cocktail is a sad cocktail"! Especially in this case served without ice, this as others state needs a well chilled glass.
