Irish Coffee

Irish Coffee: From 1940s Limerick to Global Phenomenon

1. The Birth of Irish Coffee: A Fateful Night in Limerick

Let's travel back in time to Shannon Airport in Ireland in the early 1940s. Weary travelers fill the terminal, grounded by bad weather and seeking warmth after long journeys across the Atlantic. The rainlashed windows reflect the melancholy mood.  

On one such stormy evening, the passengers of a New York flight find themselves back on Irish soil, their attempted journey home thwarted by the turbulent Irish skies. As the group sits dismayed in the terminal, longing for comfort after their ordeal, a creative chef named Joe Sheridan observes their disappointment.

In a moment of inspiration, Sheridan decides to provide spiritual warmth to these disheartened souls. After all, is not whiskey the very elixir of Ireland, known to raise sagging spirits the world over? And what better way to dispel the gloom than with robust Irish coffee, as quintessential a taste of home as exists in all of Ireland?

Joe Sheridan's Fateful Invention

Faced with a group of dejected travelers that storm-tossed night in Foynes, County Limerick, Joe Sheridan combined strong black coffee, Irish whiskey, brown sugar, and cream into an uplifting elixir that would become world-famous as Irish coffee.

The former chef and bartender at Foynes was no stranger to welcoming weary American and European travelers grounded by the temperamental Irish weather. But on this particular evening in 1942, Sheridan was moved by the bedraggled state of the New York-bound passengers who returned to the airport terminal frustrated by their aborted journey.  

Drawing on Ireland’s legendary hospitality and spirit of fun even in trying times, Sheridan improvised what was essentially hot coffee laced with Ireland’s most iconic national drink. The warmth of the steaming coffee and the kick of the whiskey indeed seemed to lift the spirits of the stranded travelers. And so was born one of the world’s most enduring coffee cocktails.

A Recipe Unchanged Through Time

Sheridan’s original Irish coffee recipe endures virtually unchanged to this day: strong black coffee brewed from quality Arabica beans, a healthy pour of whiskey, and a teaspoon of brown sugar to balance the bitterness, all crowned by a floating layer of lightly whipped heavy cream.

The coffee establishes the foundation, the alcohol provides a delightful kick, the sugar balances the bite, and the cloud-like cream adds a whimsical flourish. Each ingredient complements the others in what many aficionados consider the perfect alcohol-coffee marriage.

2. The Method and Ritual of Irish Coffee

To a large extent, Irish coffee remains popular because of the soothing ritual it inspires. More than merely a drink slapped together, Irish coffee demands care and finesse to yield that perfectly balanced first sip. 

Choosing the Ingredients

  • Coffee: Any old diner swill would do this regal drink a disservice. Only fresh high-quality coffee properly does justice to what came out of Joe Sheridan’s impromptu airport bar all those years ago. Many modern craft roasters offer specialty Irish coffee blends.
  • Irish Whiskey: Single malt is the most common choice, although single pot still or blended can also produce delicious results. Smooth tipples like Jameson, Bushmills, Tullamore Dew, or Kilbeggan work beautifully.  
  • Sugar: Some prefer simple syrup, but brown sugar has always been canon in Irish coffee for its slight molasses hint that tempers bitterness.
  • Cream: Purists insist on lightly sweetened double or whipping cream with around 35% milk fat content to allow it to float magnificently atop the coffee-whiskey blend.
The Art of the Correct Build

Making proper Irish coffee is indeed an art requiring care, technique, and a delicate touch, as follows:

  1. Warm the glassware: Heat retains flavor.
  2. Add coffee and sugar: The hot coffee dissolves the sugar.  
  3. Pour in whiskey: The magic touch of Irish spirit.
  4. Spoon float the cream: The pièce de résistance!

Pouring the cream using the back of a spoon to gently “float” it atop the coffee is the final flourish that delights both eye and tongue. In many Irish coffee bars, the floating of the cream draws oohs and aahs for its showmanship, as it transforms a humble drink into a magnificent layered spectacle.

3. How Irish Coffee Charmed America 

Irish coffee likely would have remained an obscure regional airport drink had San Francisco newspaperman Stanton Delaplane not been mesmerized by it during a 1952 trip to Ireland, bringing it triumphantly back to the City by the Bay.

Stanton Delaplane's Pivotal Role

During a flight delay at Shannon Airport in 1952, a former lawyer turned journalist Stanton Delaplane sampled his first Irish coffee. The drink dazzled his palate and warmed his spirit. Like all great journalists, he sensed a story. 

Upon returning to his native San Francisco, Delaplane convinced the legendary Buena Vista Cafe to start serving Irish coffee using the recipe he transported from Shannon. The cafe nailed the ratio after some effort and the drink became a San Francisco sensation. America at large would soon develop a fascination with Irish coffee as well.  

Perfection through Collaboration 

Replicating the delicate Irish coffee made at Shannon Airport would frustrate The Buena Vista Cafe for months until they brought over a bartender from Foynes to demonstrate the technique first-hand. The visiting Irishman revealed that the secret to floating the cream was partially whipping it first to just the right airy thickness. And so, thanks to cross-continental collaboration, flawless Irish coffee finally took hold in America.

By 1962, following a glowing endorsement by San Francisco columnist Herb Caen, The Buena Vista was serving a staggering 2,000 Irish coffees daily and sustainably popularizing the indulgent drink across America in the process.

4. The Global Spread and Evolution of Irish Coffee

The seductive taste and comforting ritual of Irish coffee has over the past half-century spawned countless interpretations globally, all riffing on Joe Sheridan’s original airport eye-opener.

International Variations 

From Asia to Australia and everywhere between, every culture that has embraced Irish coffee has also left its subtle imprint through tweaks to ingredients, technique, or presentation, including:

  • Japanese Irish coffee often features local whiskey.
  • In Italy, a shot of thick espresso sometimes augments the coffee component.  
  • Vegans float aquafaba or coconut cream rather than dairy.
  • In warmer climates like Australia, chilled Irish coffee is served over ice.
  • Some Parisian mixologists infuse funky flavors like cardamom, rose water, or elderflower into the cream.
Modern Innovations

Just as Joe Sheridan riffed on classic Irish hospitality to create the original, contemporary mixologists everywhere continue to reinvent Irish coffee while remaining true to its soul.

  • Alcohol variations now extend to aged rum, butterscotch liqueur, bourbon, or coffee-infused tequilas and vodkas.
  • Some high-end coffee bars use prized single-origin beans like Jamaican Blue Mountain in their Irish coffee.
  • Certain elite bars employ theatrical tableside service where steaming coffee is poured simultaneously into three glasses held aloft by the server.

5. Irish Coffee in Today's Craft Coffee Culture   

The global specialty coffee revolution has shone a spotlight on coffee cocktails like Irish coffee, with artisan roasters crafting complex custom blends to shine through milk and alcohol.

The Third Wave Coffee Influence 

Today’s discerning drinkers demand a higher caliber of coffee. This has pushed modern Irish coffee beyond commodity beans drowned in cream and booze into the realm of true craftsmanship.

Many specialty roasters now craft custom Irish coffee blends that stand out through flavor notes like toasted marshmallow or Madagascar vanilla instead of merely acting as an alcohol delivery vehicle. Some even experiment with partial-decaf beans to temper overstimulation from all that whiskey and caffeine!

Low Acid Beans Appeal to Modern Palates

The brightness and tanginess that today’s consumers expect from artisan coffee get neutralized by sweetened dairy and whiskey. Hence low-acid coffee varietals are gaining popularity as the base for Irish coffee, lending it more perceived acidity and a less cloying richness:

  • Beans from Brazil or Sumatra grown in mineral-rich volcanic soil offer inherent mellowness.
  • High-altitude Central American beans also display very subtle acidity owing to slower cherry maturation.
  • Partial sweeter roasts that avoid excess caramelization preserve delicate acidity otherwise destroyed via darker roasting.  
Contemporary Interpretations  

Today’s best bars approach Irish coffee with reverence - almost as a competitive sport. Custom coffee blends, small-batch artisanal whiskeys, and unexpected touches now abound, including:

  • Some acclaimed mixologists infuse cardamom or rose essence into lightly sweetened double cream for aromatics and delicate acidity to balance the sugar and whiskey. 
  • Certain West Coast bartenders add a micro foam layer between coffee and cream by shaking the dairy first in a cocktail shaker, almost cappuccino-style.  
  • Instead of sugar, acclaimed London bars may stir in chestnut honey or spiced plum preserves to bridge coffee and cream with intrigue.

6. The Cultural Significance of Irish Coffee

For legions of global devotees, Irish coffee has matured into far more than a comforting alcoholic caffeine-delivery mechanism. It endures today as a resonant touchstone of Irish culture, lore, and the very spirit of generous hospitality.

An Icon of Irish Hospitality 

Irish coffee likely endures precisely because it embodies cherished Gaelic hospitality traditions: warming weary guests with soothing drinks, entertaining visitors with delighted pomp, and sharing lively stories cementing bonds of friendship.

In Irish coffee, the steaming coffee signifies the warm mass fáilte (welcome). The whiskey mirrors Ireland’s distilling legacy spanning lifetimes. The brown sugar represents the land’s natural sweetness. And the creamy dairy floating atop reflects the emerald countryside’s verdant grazing pastures dotted with contented cattle.

Woven Into Literature, Media and Popular Culture

Irish coffee’s prominence in Ireland’s cultural identity permeates global literature, television, movies, music, and art:

  • Both classic Irish writers like Brendan Behan and contemporary ones frequently employ Irish Coffee as shorthand to connote Gaelic hospitality. Irish coffee features prominently in Irish plays and novels as both stand-in and ritual.
  • Singers Van Morrison and Sinéad O’Connor penned odes to Irish coffee’s comforting charms and role in bringing people together.  
  • On screen, everyone from gun-running IRA operatives to lovelorn Dublin poets are depicted turning to Irish coffee to warm hearts and spirits in equal measure.

Indeed, beyond just a popular drink, Irish coffee the world over denotes Gaelic generosity, joviality, and joie de vivre bottled in a steaming mug crowned by a white layer of dairy decadence. Much more than a mere beverage or cocktail, it has evolved over eight decades into a resonant cultural emblem.


As we raise our mugs in celebration of Joe Sheridan’s heartwarming 1942 invention, we honor so much more than a popular coffee drink. This simple yet gorgeous blend encapsulates everything joyous about being Irish. 

It whispers of rainy mornings on the bog. It connotes generations of smooth whiskey-making traditions. It channels sameness and community across lively pub tables. And it signifies soul-stirring Ballads sung arm-in-arm while a roaring hearth fire crackles alongside. 

Sláinte, Irish coffee - you enduring, a wondrous harbinger of Gaelic generosity and soul! May your perfect ratios and indulgent rituals forever inspire imbibers across all lands toward brotherhood, revelry, and raising a steaming mug in symbolic cèad mile fáilte.
