This old-timey cognac drink is a classic cocktail for hair-of-the-dog hangover relief. The Corpse Reviver family of cocktails was traditionally consumed as hair-of-the-dog hangover relievers, meant to refresh after a night of heavy drinking. Revivers were popular during the late 19th and early 20th century, but faded away after Prohibition. Unlike its brother, the No. 2, the Corpse Reviver No. 1 has a rich mixture of spirits with a strong Cognac base.
