Which cocktail uses vodka as the base with a black coffee liqueur, served on the rocks?

• A. Moscow Mule
• B. White Russian
• C. Black Russian
• D. Gin and Tonic

Answer: (C)

Recognize a simple, two-ingredient cocktail built on vodka with a coffee-flavored liqueur, served over ice. The drink described uses vodka as the base and a black coffee liqueur, poured over ice in a rocks glass, which is exactly the Black Russian. It’s known for its straightforward mix of vodka and coffee liqueur (often Kahlúa) without any dairy or other modifiers. The key contrast is with a White Russian, which adds cream or milk and becomes a creamy, lighter variation. The other drinks in the list don’t pair vodka with a coffee liqueur: a Moscow Mule is vodka with ginger beer and lime, and a Gin and Tonic pairs gin with tonic water. So, the cocktail fitting the description is Black Russian.
