Black Russian
The Black Russian is a cocktail of vodka and kahlua. It contains 50 ml vodka and 20 ml coffee liqueur, per IBA specified ingredients.

The drink is made by pouring the vodka and coffee liqueur over ice cubes or cracked ice in an old-fashioned glass and stirring. The Black Russian is often garnished with a lemon slice and a Luxardo maraschino cherry on a stick.

History 
The Black Russian cocktail first appeared in 1949 and is ascribed to Gustave Tops, a Belgian barman, who created it at the Hotel Metropole in Brussels in honor of Perle Mesta, then United States Ambassador to Luxembourg. The cocktail owes its name to the use of vodka, a typical Russian spirit, and the blackness of the coffee liqueur.
