This is a unique little cocktail that host of "The Cocktail Spirit," Robert Hess, created a few years ago. It is an excellent way to illustrate the the valuable role that dry vermouth can play in a properly balanced drink.

To mix the black feather cocktail you will need brandy, vermouth, Cointreau, and bitters. Watch this video beverage making tutorial and learn how to mix the black feather cocktail.
