The Irish Car Bomb is a beer-based cocktail made by dropping a shot of Irish cream and Irish whiskey into a glass of Irish stout, usually Guinness. The drink is controversial because its name references the car bombings associated with The Troubles in Northern Ireland, and some bartenders avoid the term or refuse to serve it. Alternative names include Irish Slammer, Irish Bomb Shot, and Dublin Drop.

Composition and preparation

The drink is usually made with Irish cream and Irish whiskey in a shot glass, which is then dropped into Irish stout such as Guinness. It is served and consumed immediately because the mixture can curdle or lose its intended texture.

Origin

Most modern references place the drink’s invention in the United States, with accounts commonly citing Connecticut and the late 1970s. The exact origin story varies across sources, but none identify it as an Irish creation.

Name and controversy

The name combines the Irish ingredients with a reference to car bombings, making it offensive to many people, including some bartenders and drinkers. As a result, some venues and publications prefer substitute names.
