How many different liqueurs are used in a B-52?

A B-52 is a layered shot that traditionally consists of three distinct liqueurs, which contribute to its unique flavor profile and visual presentation. The liqueurs commonly used are Kahlúa (coffee liqueur), Baileys Irish Cream (cream liqueur), and Grand Marnier (orange-flavored liqueur). Each layer is poured carefully to create a striking appearance, with Kahlúa at the bottom, followed by Baileys, and finished with Grand Marnier on top.

The use of these three different liqueurs not only enhances the drink's complexity but also showcases the bartender's skill in layering, which is an important technique in cocktail preparation. This is why the answer indicating three different liqueurs is correct. The drink embodies a balance of flavors from the coffee, cream, and citrus notes that come from the three ingredients.
