There are few drinks in the world with a story as vivid and romantic as Irish Coffee. It was born not in a city bar or a grand hotel, but in a small flying-boat terminal on the banks of the River Shannon in County Limerick, during the bitter winter of 1943. Foynes was, in those extraordinary wartime years, one of the busiest transatlantic air hubs in the world — a stopping point for passengers making the long, turbulent crossing between Europe and North America. When a flight turned back to Foynes one stormy night after battling brutal Atlantic weather, the terminal chef, Joe Sheridan, was asked to prepare something warming for the cold and weary passengers. He brewed strong coffee, stirred in sugar and a generous measure of Irish whiskey, then floated softly whipped cream over the top. When one American passenger asked whether they were drinking Brazilian coffee, Sheridan reportedly smiled and replied: “No, that’s Irish Coffee.” (Read the full story of the chef who invented Irish Coffee for the complete tale.)
The drink spread slowly but surely across the world, carried in part by a San Francisco journalist named Stanton Delaplane, who encountered it at Shannon Airport in the early 1950s after Foynes had given way to the new terminal. He loved it so much he helped introduce it to the Buena Vista Café in San Francisco, where it became a sensation. But the heart of Irish Coffee remains firmly in Ireland — and nowhere more so than at the Foynes Flying Boat and Maritime Museum, where Joe Sheridan’s creation is still celebrated and served with enormous pride. To make it properly at home is to connect with that whole extraordinary chapter of Irish history.
The genius of Irish Coffee lies in its simplicity and its balance. Strong, bitter coffee; sweet sugar; warming whiskey; and cool, lightly whipped cream that sits on top and is sipped through rather than stirred in. It is not a cocktail to be fussed over with exotic syrups or flavoured creams. Done properly, it is one of the most satisfying drinks ever conceived — warming, rich, and utterly Irish.
Ingredients
- 150ml (5 fl oz) freshly brewed strong hot coffee — filter or cafetière, not instant
- 45ml (1½ fl oz / 1 standard measure) Irish whiskey — a blended whiskey such as Jameson or Powers works beautifully
- 1–2 teaspoons light brown or white sugar, to taste (brown adds a gentle depth)
- 60ml (2 fl oz) fresh double cream, lightly whipped to soft, barely-holding peaks — it must still be pourable

- Warm your glass. This step is not optional — a cold glass will chill the drink and prevent the cream from floating properly. Fill a heatproof stemmed glass (a 200–240ml / 7–8 fl oz capacity is ideal) with boiling water and leave it for thirty seconds, then pour the water away.
- Add the sugar. While the glass is still warm, spoon in your sugar. One teaspoon gives a gentle sweetness; two makes it noticeably sweeter. The sugar is not simply a garnish — it is part of the structure of the drink and helps the cream to float.
- Add the whiskey. Pour in your measure of Irish whiskey over the sugar.
- Pour in the hot coffee. Fill the glass to about three-quarters full with your freshly brewed, piping-hot coffee — roughly 150ml (5 fl oz). Stir well until the sugar is completely dissolved. The liquid should be very hot at this stage.
- Float the cream. This is the defining moment. Hold a large spoon upside down, curved side up, just above the surface of the coffee. Pour the lightly whipped cream slowly over the back of the spoon so it settles gently onto the surface of the hot coffee. It should form a distinct, smooth layer roughly 1cm (½ inch) deep. If the cream is too stiffly whipped it will sit in a lump; if it is too liquid it will sink. You are aiming for the consistency of a thick pouring cream — just holding its shape.
- Serve immediately, without stirring. The pleasure of Irish Coffee is in sipping the hot, whiskey-spiked coffee through the cool, silky cream.
Tips
- Use freshly brewed coffee — a strong cafetière or filter brew is ideal. Weak coffee will be overwhelmed by the whiskey and cream.
- The cream must be softly whipped. Whip it by hand or with a whisk until it just begins to hold — it should pour in a thick ribbon. Over-whipped cream will not float smoothly.
- A pre-warmed glass is essential every time. The temperature differential between hot liquid and cold glass is the most common reason Irish Coffee fails at home.
- Do not be tempted to use flavoured whiskies or cream liqueurs — they muddy the clean, honest balance that makes the original so wonderful.
- Brown sugar is traditional in many Irish households and adds a faint caramel warmth that sits beautifully with the whiskey.
There is something genuinely moving about making Irish Coffee at home — knowing that this simple combination of four ingredients was stirred together on a dark winter’s night in wartime Limerick to comfort cold travellers, and that it has been bringing warmth and pleasure to people ever since. Raise a glass to Joe Sheridan, to Foynes, and to the enduring, quietly brilliant generosity of Irish hospitality.
