What is the ratio of vodka to Kahlua in a Black Russian?

In a Black Russian, the traditional recipe calls for a specific ratio of vodka to Kahlua that creates a strong, rich flavor profile. The correct ratio is 2/3 vodka to 1/3 Kahlua. This balance allows the vodka's strength to complement the sweetness and coffee flavor of Kahlua without overpowering it.

The drink typically consists of two principal ingredients, and the emphasis on the vodka reflects the cocktail's identity as a robust, spirit-forward beverage. By using more vodka, the drink maintains its intended character, allowing for the distinctive taste of Kahlua to enhance the overall experience without becoming too sweet.

Understanding this ratio is essential for bartenders as it affects not only the taste but also the consistency of the drink served. A proper adherence to the recipe ensures that customers receive a Black Russian as it is traditionally intended, with the right blend of flavors.
