What Is Irish Coffee and How to Drink It

If you’ve ever wondered what makes Irish coffee so special—or why it feels like drinking a hug in a mug—you’re not alone. This iconic drink blends bold coffee, smooth whiskey, sugar, and cream into something more than the sum of its parts. But what does it really taste like, and where did it come from? The answer isn’t just in the recipe. It’s in the story.

A true Irish coffee contains hot brewed coffee, Irish whiskey (typically 1½ to 2 oz), 1 tsp of brown sugar, and is topped with lightly whipped heavy cream. The cream floats on top and is not mixed in—so you sip the coffee through it. That first legendary cup, allegedly created in 1942 at Shannon Airport, was made with a tear in the foam. Its signature bitterness comes from both the whiskey and that emotional backstory.

What Is Irish Coffee, Really?

Irish coffee is not just a coffee with booze in it—it’s a balanced cocktail where hot coffee meets Irish whiskey, lifted with sugar and crowned with floating cream. The coffee provides warmth and bitterness, the whiskey adds depth and fire, the sugar balances the flavors, and the cream softens the finish. Unlike a latte or a mocha, it is not a milk-forward drink. The cream should always be poured gently over the back of a spoon so it rests on top, creating contrast in each sip.

The Romantic (and Accidental) Origins of Irish Coffee

The drink was invented in 1942 at Foynes Airport (later moved to Shannon Airport) by a bartender named Joe Sheridan. One night, a group of American passengers arrived during a snowstorm. To warm them up, Sheridan added Irish whiskey to their coffee. One traveler asked, “Is this Brazilian coffee?” Sheridan replied, “No, that’s Irish coffee.” The story goes that Sheridan later created a special menu just for a flight attendant he admired. He added Irish coffee to it—but she didn’t order it for a full year. When she finally did, Sheridan was so moved he cried while making it—and a tear rolled into the cup, adding an extra note of bitterness to the foam. She became the first person to order his signature drink.

Why Irish Coffee Works: Flavor Science and Balance

The magic of Irish coffee lies in its contrasting elements. The hot, bitter coffee contrasts with the smooth, warming whiskey. Sugar bridges the two, while the cream acts as a silky buffer. It’s a layered drink: you taste the coffee first, then the whiskey as you sip, and finally the cream softens the finish. The traditional preparation calls for hot, strong brewed coffee—not espresso. Irish whiskey, typically around 40% ABV, is preferred for its smooth, slightly sweet profile. The cream must be lightly whipped, not too stiff, so it floats and can be sipped through.

Ireland Beyond Coffee: Landmarks and Lore

Beyond its coffee culture, Ireland is steeped in history and natural beauty. The River Shannon, at around 400 km long, is the country’s longest river. It originates near the Cuilcagh Mountains, with its source at Shannon Pot. The river flows through lakes, plains, and wetlands before reaching the Atlantic. Along its banks lie charming towns and historic sites. One such place is Clonmacnoise, a 6th-century monastic city known as the “Island of Saints and Scholars.” At the river’s mouth lies the town of Shannon, which hosts medieval banquets and an annual regatta that draws over 100,000 visitors. Dublin Castle, originally built in the 13th century and rebuilt after a fire in the 18th century, also offers a deep dive into Ireland’s colonial and cultural past, with its State Apartments and Saint Patrick’s Day celebrations.

Frequently Asked Questions

What is the correct way to make Irish coffee?

To make Irish coffee the traditional way, pour hot brewed coffee (not espresso) into a warmed glass mug, add 1 tsp of brown sugar, and stir until dissolved. Add 1½ to 2 oz of Irish whiskey, then carefully float lightly whipped heavy cream on top by pouring it over the back of a spoon. Do not stir after adding the cream—you sip the coffee through the cream.

What kind of whiskey is used in Irish coffee?

Irish coffee traditionally uses Irish whiskey, usually a smooth, around 40% ABV bottling. Popular choices include Jameson or Tullamore D.E.W., but any high-quality Irish whiskey with a clean, slightly sweet profile works well.

Do you mix the cream into Irish coffee?

No, the cream is not mixed in. It is poured on top of the coffee and whiskey mixture and should be sipped through. This layering is essential to the experience—the coffee and whiskey are tasted first, followed by the cream.

Why is it called Irish coffee?

It’s called Irish coffee because it was invented in Ireland, specifically at Foynes Airport (later Shannon Airport), by a bartender named Joe Sheridan. He added Irish whiskey to coffee to warm up cold passengers, and the name stuck.

Can you use espresso in Irish coffee?

Traditional Irish coffee is made with hot brewed coffee, not espresso. Using espresso changes the flavor balance and texture, making it more like a coffee liqueur drink. For authenticity, stick with brewed coffee.

The first legendary Irish coffee was made by bartender Joe Sheridan for American passengers during a snowstorm in 1942. Later, he created a private menu for a flight attendant he admired.
