Dec 13, 2020 Diamondback Cocktail The Diamondback cocktail first appeared in Ted Saucier's book Bottom's Up, published in 1951. Created at the Diamondback Lounge once located in the Lord Baltimore Hotel in Baltimore, Maryland. The lounge & cocktail were named after the Diamondback terrapin turtle. This turtle species is very common to the east coast and is the Maryland state reptile and the University of Maryland's mascot.The Diamondback consists of Rye whiskey, Calvados, and Yellow Chartreuse. It has lovely herbaceous notes and slight sweetness from the Chartreuse. The rye brings the spiciness, and the apple brandy helps balance everything. It's a fantastic cocktail for Chartreuse lovers, as it's the star in this classic.- Tiffany Glidden
