In the quiet hum of an Irish air terminal in the 1940s, weary travelers shivered from Atlantic winds. A chef reached for hot coffee, sugar, whiskey, and cream—simple ingredients that would soon ignite a global ritual.
The Irish Coffee is more than a drink; it’s an act of hospitality. A bridge between comfort and craft, warmth and spirit. Beneath its creamy top lies a story of ingenuity, Irish pride, and the pursuit of something that feels like coming home.
I. Origins
The Irish Coffee was born from cold and compassion.
In 1943, a Pan Am flying boat bound for New York was forced to turn back to Foynes Airbase, County Limerick—an important transatlantic refueling stop during the war. Passengers, weary and chilled, disembarked to find refuge in the terminal restaurant.
Chef Joe Sheridan, moved by their exhaustion, decided to serve something more comforting than plain coffee. He added Irish whiskey and brown sugar to the brew, then floated lightly whipped cream on top.
When a traveler asked if it was Brazilian coffee, Sheridan smiled:
“No,” he said. “That’s Irish coffee.”
It was hospitality in a glass—a fusion of warmth, strength, and sweetness that captured the Irish spirit itself.
II. Historical Evolution
From Foynes to the World
In 1945, Foynes was replaced by Shannon International Airport, and Sheridan continued his work there. Among his visitors was Stanton Delaplane, a travel writer for the San Francisco Chronicle, who brought the recipe back to the United States.
Delaplane shared it with Jack Koeppler, owner of The Buena Vista Café in San Francisco. Recreating the floating cream proved tricky—the cream either sank or mixed into the coffee.
Koeppler and Delaplane even traveled to Ireland to study Sheridan’s technique. Upon returning, they perfected the method by aging cream slightly and lightly whipping it to the ideal consistency.
By the early 1950s, the Buena Vista Café was serving thousands of Irish Coffees daily, cementing the drink as an American classic with Irish soul.
Mid-Century Expansion
Through the 1960s and 1970s, the Irish Coffee became a staple of hotel lounges and winter menus worldwide. Variations appeared—some with heavy cream, others with Bailey’s Irish Cream (invented in 1974). But purists always returned to Sheridan’s original formula: coffee, sugar, whiskey, and cream—no shortcuts.
Modern Revival
Today, Irish Coffee is experiencing a renaissance in craft bars, where bartenders respect its heritage while refining technique. Specialty coffee roasts, precise whiskey pairings, and temperature control have elevated it from comfort drink to high craft.
III. Ingredients & Technique
Irish Coffee is an architectural drink—each layer essential, each element demanding care.
Core Components
Coffee: Fresh, hot, and strong—preferably a medium-dark roast with nutty or chocolate undertones.
Whiskey: Irish whiskey for smoothness and gentle spice. Brands like Jameson, Powers, or Redbreast work beautifully.
Sugar: Demerara or brown sugar adds depth and a hint of caramel.
Cream: Fresh heavy cream, lightly whipped so it floats elegantly atop the coffee.
Temperature, texture, and timing are everything. The cream must float, not mix—creating a warm-below, cool-above contrast that defines the drink’s character.
IV. Cultural Significance
The Irish Coffee embodies Irish hospitality—simple, generous, and rooted in warmth.
It’s a drink of contrast and balance: hot vs. cold, bitter vs. sweet, sober vs. spirited. It’s both dessert and digestif, a gesture of care and craftsmanship.
In Ireland, it’s a symbol of national pride and storytelling—served at pubs and homes alike, especially during cold months and festive gatherings. Abroad, it became a cultural ambassador, introducing countless drinkers to Irish whiskey long before the global whiskey boom.
Beyond flavor, Irish Coffee captures something universal: the pleasure of slowing down and sharing comfort, one steaming cup at a time.
V. How to Make the Classic Version Today
Recipe — The Classic Irish Coffee
Ingredients
2 oz (60 ml) Irish whiskey
4 oz (120 ml) hot, freshly brewed coffee
2 tsp brown sugar (or 0.5 oz / 15 ml demerara syrup)
1 oz (30 ml) lightly whipped heavy cream
Method
Preheat an Irish Coffee glass with hot water, then discard the water.
Add brown sugar to the warm glass.
Pour in hot coffee and stir until sugar dissolves.
Add Irish whiskey and stir briefly.
Float lightly whipped cream over the back of a spoon to form a distinct top layer.
Serve immediately—no straw, no stirrer.
Specs
Glass: Irish Coffee mug or heatproof stem glass
Temperature: Hot coffee, cool cream
Garnish: None (the cream is the garnish)
Style: Layered, hot cocktail
Technique Notes
Whip cream only until thickened—not stiff. It should pour smoothly.
Use freshly brewed coffee; staleness destroys the balance.
Never add ice—the drink’s charm lies in the hot/cold contrast.
Variations & Lineage
Bailey’s Irish Coffee: Substitute half the whiskey with Irish cream liqueur.
Cold Brew Irish Coffee: Serve over ice with chilled coffee for a modern summer take.
Smoky Irish Coffee: Add a barspoon of peated Scotch for depth.
Spiced Irish Coffee: Infuse cream with cinnamon or nutmeg for festive flair.
Service & Pairing Tip
Perfect after dinner or during cold weather.
Pair with chocolate desserts, scones, or Irish soda bread.
VI. Modern Variations & Legacy
The Irish Coffee has evolved alongside coffee culture itself. Modern bartenders experiment with single-origin espresso, nitro cold brew, or even espresso martini hybrids, while staying faithful to Sheridan’s spirit.
In Ireland, many pubs still serve it with reverence—sugar cubes, rich whiskey, and a carefully floated cream cap. The Buena Vista Café continues to pour over 2,000 Irish Coffees a day, a living monument to one of the world’s great hospitality stories.
The legacy of the Irish Coffee lies not in novelty, but in execution. When made well, it’s perfect—an edible poem of comfort and balance.
As Sheridan himself once said:
“An Irish Coffee should be hot as hell, sweet as a kiss, and strong as a friendly hand.”
