What is the primary flavoring in a Black Russian?

The primary flavoring in a Black Russian is coffee liqueur. This cocktail is traditionally made by combining vodka and coffee liqueur, which is what gives it its distinctive rich and robust flavor profile. The coffee liqueur provides a deep, slightly sweet taste that complements the neutral spirit of the vodka, making it the star flavor of the drink.

Other options, while they may have their own unique tastes, do not contribute to the identity of a Black Russian in the same way. Chocolate liqueur, cream, and amaretto are not foundational to this cocktail's formulation and would lead to a completely different beverage. The importance of coffee liqueur in defining the drink's flavor is why it is recognized as the primary flavor in a Black Russian.
