Irish coffee explained
Irish coffee has a well-documented origin and a simple recipe. It still trips people up, mostly at the cream. Here is where it came from and how to make one that looks and tastes right.
A drink with a well-told origin
The usual story is well documented. In the 1940s Joe Sheridan, a chef at the flying boat terminal at Foynes in County Limerick, served hot coffee laced with whiskey and topped with cream to cold, tired transatlantic passengers. In 1952 the travel writer Stanton Delaplane brought the idea to the Buena Vista Cafe in San Francisco, where it became famous.
Whatever the embellishments, the drink has stayed close to that original: hot coffee, Irish whiskey, sugar and cream. It is a rare cocktail whose recipe has barely changed in eighty years. That stability makes it a good drink to learn on, because when it goes wrong the fault is almost always in the technique rather than the recipe.
Irish whiskey is a defined spirit
Irish whiskey must be distilled and matured on the island of Ireland, in wooden casks, for at least three years. Within that rule there are several styles, including single malt, grain and single pot still, made from malted and unmalted barley together. Our guides to the rules that define Irish whiskey and single pot still go deeper.
For Irish coffee, a smooth, standard blended Irish whiskey is the norm. Its soft, slightly sweet profile sits well with coffee. A pot still whiskey gives a spicier, oilier version that many bartenders prefer.
Four parts and a proportion
A common build uses a stemmed, heat-proof glass of around 200 ml:
- About 120 ml of hot, strong black coffee.
- Two teaspoons of brown sugar.
- 40 ml of Irish whiskey.
- A layer of lightly whipped cream about 2 cm thick.
Warm the glass with hot water first and tip it out. Add the sugar and coffee and stir until the sugar fully dissolves. Add the whiskey. Then float the cream on top.
Sugar is what holds the cream up
The sugar is not only for sweetness. Dissolved sugar makes the coffee denser, which helps the cream float in a clean layer rather than sinking into a muddy mix. Skip the sugar and the cream often slumps through.
Whip the cream until it has just thickened and still pours, like melted ice cream. Stiff peaks sit on top in a lump and do not blend as you drink. Pour it slowly over the back of a warm spoon held just above the coffee. Indian packaged fresh cream is often lower in fat than whipping cream and floats less reliably. Use whipping cream if you can find it and keep it well chilled.
Drink it through the cream
Do not stir an Irish coffee. You sip the hot, sweet, boozy coffee through the cold cream collar, so every mouthful has both temperatures. That contrast is the point of the drink.
Serve it straight away. The cream warms and the coffee cools within a few minutes. Then the effect is gone. Make one at a time rather than lining up a tray.
Coffee choices in India
Use freshly brewed coffee, not instant. A French press or a strong pour-over works well. South Indian filter coffee, often blended with chicory, is strong and dark, which suits the drink. Chicory adds bitterness, so you may want a touch more sugar.
Brew it stronger than you would drink it black, since the whiskey and cream will soften it. Arabica from the hills of Karnataka, Kerala or Tamil Nadu gives a smoother cup than a harsh dark roast.
Common mistakes
- Cold glass. The drink cools before you finish it. Always preheat.
- Too much whiskey. Beyond 40 to 50 ml the alcohol fights the coffee and the drink becomes harsh.
- Weak coffee. The cream and whiskey need a strong brew to stand up to them.
- Aerosol cream. It dissolves into the coffee almost at once and tastes of very little.
- Stirring. It ruins the layered effect that makes the drink.
Fix those five and your Irish coffee will be better than most served in bars. None of them needs special equipment, just attention to temperature and order.
Caffeine does not sober you up
Irish coffee combines alcohol and caffeine. The caffeine may make you feel more alert, but it does not reduce the effect of the alcohol. Treat it as a single after-dinner drink and never drive after it.
Your first step: make one with decaf to practise the cream float without the late-night buzz. Once your cream sits in a clean layer every time, switch to your usual coffee and pay attention to how the whiskey's sweetness meets the bitterness of the brew.
Common questions
Why does my cream sink in Irish coffee?
The cream is usually overwhipped or underwhipped, or there is not enough sugar in the coffee. Whip it to a pourable thickness and pour over the back of a spoon.
What whiskey should I use for Irish coffee?
A smooth blended Irish whiskey is traditional. Single pot still whiskey gives a spicier version.
Should you stir Irish coffee?
No. Drink the hot coffee through the cold cream layer so each sip has both.
