What Is Irish Coffee and How Did It Start?

In the cobbled lanes of Dublin’s old city, where harp music drifts through narrow alleys and weathered stone walls glow under soft light, there’s a drink that tastes like nostalgia, warmth, and a touch of magic. It’s not just coffee with booze—it’s something deeper. But what exactly makes a real Irish coffee stand out, and why does it feel like a love story in a cup?

An authentic Irish coffee combines hot black coffee, Irish whiskey, brown sugar, and a whipped cream float—served in a warmed glass. The traditional recipe uses 1 shot (30ml) of Irish whiskey, 1 teaspoon of brown sugar, hot strong coffee to fill, and a final float of lightly whipped cream.

The Flavor of Authentic Irish Coffee

True Irish coffee is bold and warming. The base is freshly brewed black coffee—strong, not bitter—with a full-bodied mouthfeel. Irish whiskey adds depth and a slight smokiness, while brown sugar balances the bitterness with molasses-like sweetness. Topped with a float of cold, lightly whipped cream, the contrast is key: you sip the coffee through the cream, not stir it in. That first taste—warm, sweet, boozy, and creamy—is layered, nostalgic, and uniquely comforting.

The Romantic Legend Behind the Drink

The story goes back to Shannon Airport in the 1940s, but the version most people know happened at Foynes Flying Boat Terminal—and later, Dublin Airport. A bartender there, named Joe Sheridan, fell for a beautiful air stewardess. She always ordered coffee, never cocktails. One night, hoping to impress her, he mixed coffee with Irish whiskey and sugar, creating what we now know as Irish coffee. He even went so far as to create a special drinks list with just that one cocktail on it—for her. She didn’t try it for a whole year. When she finally did, Sheridan was so emotional he cried while making it, and a tear rolled into the drink. He wiped it away, but not before it left a salty-sweet trace on the rim. Some say that’s why the first sip of a well-made Irish coffee still carries a hint of bittersweet longing.

How to Make an Irish Coffee the Traditional Way

Making an Irish coffee isn’t hard, but there are key steps to get it right:

• Use freshly brewed strong black coffee—filter or plunger style works best.
• Preheat a stemmed glass (traditionally a clear tulip-shaped glass) by filling it with hot water, then dumping it out.
• Add 1 teaspoon of brown sugar to the warm glass.
• Pour in 150–180ml of hot coffee and stir until the sugar dissolves completely.
• Add 30ml of Irish whiskey (Jameson or Tullamore DEW are common, but any good-quality Irish whiskey works).
• In a separate bowl, gently whip heavy cream (don’t over-whip—it should be pourable, not stiff).
• Pour the cream over the back of a spoon so it floats on top of the coffee. Do not stir after adding the cream—the coffee is meant to be sipped through the cream.

Why the First Sip Feels Different

According to the legend, the very first Irish coffee ever served had a tear in it—a literal saltwater tear from the bartender. While we can’t confirm that detail, many who drink a properly made Irish coffee say the first sip feels deeper, almost nostalgic. Perhaps it’s the contrast of the cool cream against the warm coffee, or the gentle burn of the whiskey, or just the idea behind the drink. Either way, that first taste often lingers longer than others.

Frequently Asked Questions

What is the original Irish coffee recipe?

The original Irish coffee recipe includes hot black coffee, 30ml of Irish whiskey, 1 teaspoon of brown sugar, and a float of lightly whipped cream. The coffee is stirred to dissolve the sugar, whiskey is added, and then the cream is floated on top without mixing. The cream should be pourable, not stiff, and poured over the back of a spoon.

Do you stir Irish coffee?

No, you do not stir an Irish coffee after adding the cream. The coffee is sipped through the floating cream, which preserves the contrast between the hot, spiced coffee beneath and the cool, smooth cream on top.

What kind of whiskey is used in Irish coffee?

Traditional Irish coffee uses Irish whiskey, such as Jameson or Tullamore DEW. The whiskey should be smooth and not overly peaty, as the goal is to complement the coffee, not overpower it.

Why is there cream on top of Irish coffee?

The cream floats on top of Irish coffee to create a contrast in temperature and texture. You’re meant to sip the hot coffee through the cold cream, which enhances the drinking experience and balances the flavors.

Can you make Irish coffee with other types of alcohol?

Technically, you can, but it wouldn’t be an Irish coffee. The drink specifically uses Irish whiskey. Using other spirits would make it a different cocktail altogether.

What kind of coffee is best for Irish coffee?

A strong, full-bodied black coffee is ideal. Filter or French press coffee works well. Avoid espresso unless you want a much more intense, bitter profile. The coffee should be hot but not scalding.
