Irish Car Bomb: Delicious, But Don’t Call It That

Irish Car Bomb recipe

The Irish Car Bomb is a controversially named drink that has become a staple in many bars across the globe, particularly popular on St. Patrick’s Day.

From a technical standpoint, this beverage constitutes a Boilermaker, a renowned drink featuring a shot of liquor, typically whiskey, savored alongside a beer.

The shot component comprises a blend of Bailey’s Irish cream and Irish whiskey, commonly Jameson. As for the beer selection, it’s the iconic Guinness. The ritual involves dropping the shot into the Guinness pint, imbibing swiftly, and perhaps indulging in repeats.

It’s a perennial favorite for kickstarting festivities on St. Patrick’s Day and lively gatherings throughout the year.

This guide will explore how to make an Irish Car Bomb, offering insights into each ingredient and tips for enjoying this dynamic beverage responsibly.


Irish Car Bomb Ingredients

  • Irish Whiskey (1/2 ounce / 15 ml): The Irish whiskey adds a smooth, slightly spicy layer to the drink, infusing it with a warmth that contrasts beautifully with the cool, creamy Baileys.
  • Baileys Irish Cream (1/2 ounce / 15 ml): This liqueur adds a rich, velvety texture and a sweet flavor profile that includes notes of chocolate and cream, serving as the perfect bridge between the whiskey and the Guinness.
  • Guinness Beer: A dark Irish stout that is almost synonymous with Irish culture itself. Its deep, roasted flavors and creamy head add body and complexity.

Irish Car Bomb Recipe

  1. Layering the Shot:
    • Begin by carefully pouring 1/2 ounce (15 ml) of Baileys Irish Cream into a shot glass. Next, gently layer 1/2 ounce (15 ml) of Irish whiskey on top.
    • The layering can be achieved by slowly pouring the whiskey over the back of a spoon held just above the Baileys, creating a visually appealing separation between the two.
  2. Preparing the Guinness:
    • Fill a pint glass half to three-quarters full with Guinness beer. Allow the stout to settle for a moment, ensuring you get a perfect blend of the beer’s body and its creamy head.
  3. The Drop:
    • With both the shot and the pint prepared, the next step is to drop the shot glass itself into the pint of Guinness. This is done in one swift motion, causing the ingredients to mix rapidly.
  4. Consumption:
    • The Irish Car Bomb is intended to be consumed immediately after the shot is dropped into the pint glass. The rapid mixing of the Baileys and the acidic environment of the beer causes the cream to curdle if left too long.
  • Alternate Names: Many establishments and individuals prefer to use alternative names for this drink to avoid the negative connotations associated with the original name. Some simply call it an “Irish Bomb” or “Irish Slam Shot.”

The Irish Car Bomb – (Don’t Call It That)…

Conceived in 1979 by Charles Burke Cronin Oat, the erstwhile proprietor of Wilson’s Saloon in Norwich, Connecticut, the Irish Car Bomb quickly became a staple in Irish pubs and bars across the U.S.

Ideal for St. Patrick’s Day festivities, this delightful beer-and-a-shot pairing is enjoyable throughout the year. The Irish Car Bomb falls under the Boilermaker category, where traditionally a whiskey shot is plunged into a beer. However, this version uniquely combines whiskey with Irish cream before taking the plunge.

To make an Irish Car Bomb, gather Irish whiskey, Baileys Irish Cream, and Guinness. Mix equal parts whiskey and Irish cream in a shot glass—pouring the cream first, followed by a gentle layer of whiskey on top—then drop it into a half-filled glass of Guinness.

Though it’s usually wise to sip rather than gulp, the Irish Car Bomb is an exception.

Drinking it swiftly prevents the Irish cream from curdling in the acidic beer, ensuring a smooth experience.

While the classic approach involves dropping the shot glass into the beer, some prefer to mix the three components directly in the beer glass for a simpler, albeit less dramatic, consumption method.

Originally dubbed the Irish Car Bomb, the name has since been abandoned due to its controversial connotations, especially in Ireland. The shift reflects a growing sensitivity, and it’s recommended to avoid using the original name, opting instead for “Irish Shot” when ordering, particularly on Irish soil.
