Cocktail History
The Endless Night is a modern cocktail that was created by author Jassy Davis and was first published in her book Winter Warmers: 60 Cosy Cocktails for Autumn & Winter. Based on the Black Russian, it calls for the classic’s combination of spirit and coffee liqueur but substitutes the vodka for molasses-rich dark rum and tops it all with aromatic bitters and soda.

To make this cocktail, you’ll need the following ingredients:
Coca-Cola: This is a carbonated soft drink made with coca leaf extract, caffeine, sugar, and carbonated water.
Smith & Cross Rum: This is a type of rum made with molasses or sugarcane juice, spices, and alcohol that has been barrel aged for a long period of time. This recipe specifically calls for Smith & Cross Traditional Jamaican Rum.
Coffee Liqueur: This is a liqueur made with coffee, spices, sugar, and alcohol. I used Kahlúa Coffee Liqueur.
Aromatic Bitters: This is a food product made with botanicals, herbs, and alcohol. I used Angostura Aromatic Bitters.

Jigger: This is used to measure and pour ingredients. I used the Japanese jigger from the A Bar Above 14-Piece Silver Bar Set.

Tasting Notes

Kendall’s Rating: ⭐⭐⭐⭐
Kendall’s Take: “I only recently picked up a bottle of Smith & Cross rum, which is notorious for its uniquely funky flavor. I’ll admit, I don’t think I really cared all that much for any of the other drinks I’ve tried it in because I like a more classic rum flavor, but this cocktail might change my mind if I have it a few times. I do think I’d like this even more with another less prominent rum, but overall, it was very tasty. The soda cuts the rum well, while the coffee liqueur rounds out the aftertaste with a noticeable sweetness. The Endless Night probably won’t land in my at-home rotation because I try to avoid soda, but I would drink this again in a pinch at a bar since most would likely have the ingredients on hand.”
