Coffee Liqueur. It is marketed in a special bottle, with two sections separated by glass. In one of the sections, there is a black liqueur, made with coffee and whiskey. In the other, there is a white milk chocolate liqueur.
When serving, the white liqueur must be placed delicately over the black liqueur, and the glass that receives the drink must be tilted during this operation.
