This potent cocktail marries apple spirit with rye whiskey and rich herbal Chartreuse. An after-dinner/nightcap tipple.
Adapted from Ted Saucier's 1951 Bottoms Up book in which the author calls for two parts rye whiskey, one part applejack and one part yellow Chartreuse. The Diamondback Lounge Cocktail, as its properly named, was the signature drink at the Diamondback Lounge bar which lie within the Lord Baltimore Hotel. This historic 22 story hotel opened in 1928 and still graces the skyline of Baltimore, Maryland to this day, although sadly the Diamondback Lounge has long gone.
The cocktail, and indeed the lounge bar where it originated, are named after the diamondback terrapin, a species of turtle common to the tidal marshlands of America's east coast which, as its name suggests, has a diamond pattern on top of its shell. Since 1932, the turtle has been the University of Maryland's school mascot and is also the Maryland State Reptile.
