Coffee cocktails - espresso martini and irish coffee
Coffee and alcohol meet in a glass more often than you might think, and two cocktails have grown into real classics: the espresso martini and irish coffee. The first is a cold, energising drink based on fresh espresso and vodka, with a characteristic foam on top. The second is a hot, warming drink of coffee, Irish whiskey, sugar and a layer of thick cream. Both show how well coffee can work with alcohol if made thoughtfully. They also have colourful histories, one from a London bar of the 1980s, the other from an Irish airport in wartime. Here is where they came from, what their secret is, why the quality of the coffee matters so much and how to prepare both at home so they truly taste good.
Two pillars of coffee cocktails
The espresso martini and irish coffee are two poles of the coffee cocktail world. The espresso martini is cold, elegant and stimulating, served in a cocktail glass with a foam of crema. Irish coffee is hot, creamy and warming, served in a handled glass with a floating layer of cream. They share the fact that in them coffee is not an addition but the main character, and alcohol its partner. Almost everything else differs: temperature, alcohol, manner of serving and mood. Interestingly, irish coffee arose nearly forty years before the espresso martini and can be considered its spiritual ancestor. Getting to know both is a good lesson in how differently coffee can shine in the company of alcohol.
The birth of the espresso martini
The espresso martini has one of the best anecdotes in the world of bars. It was created around 1983 by the legendary bartender Dick Bradsell in London’s Soho, when a customer asked for a drink that would wake her up and put her on her feet. Bradsell combined fresh espresso, sugar and vodka, creating a drink that was at once stimulating and intoxicating. At first he called it the vodka espresso and served it over ice, without coffee liqueur. Over time coffee liqueur was added, and by the end of the 1990s the drink moved into an elegant glass and took the name espresso martini. Today it is one of the most popular cocktails in the world. Its history shows that even iconic drinks often arise from a simple, concrete need of a guest at the bar.
Why crema decides
The secret of a good espresso martini is the crema, that is the creamy foam on the surface of fresh espresso. It is what forms the characteristic smooth layer on top of the drink, which is its hallmark. The key is to use hot, freshly brewed espresso and to shake it immediately with the rest of the ingredients. When the espresso cools, the crema disappears, and the drink loses its foam and look. Vigorous shaking with ice aerates the drink and sets the foam, which is why an espresso martini is always shaken, not stirred. This shows how strongly the quality and freshness of the coffee affect the final result. You can read more about crema and what it really means in the post on espresso crema. Without good crema there is no good espresso martini.
The classic espresso martini recipe
A good espresso martini rests on a few simple rules. The base is fresh, hot espresso, plus vodka, coffee liqueur and a touch of sugar syrup for balance. Everything goes into a shaker with plenty of ice and is shaken vigorously, until the drink is well chilled and aerated. It is strained into a chilled cocktail glass, and a layer of foam settles on top. The classic garnish is three coffee beans. The key is proportion: the drink should be neither too sweet nor too bitter, but balanced. The most common mistake is using cold or old espresso, which will not give foam. A well-made espresso martini is velvety, coffee-forward and stimulating, and its success starts with the quality of the coffee itself.
The birth of irish coffee
Irish coffee has an equally cinematic history, reaching back to wartime. It arose in 1943 in a small restaurant at the airport in Foynes, Ireland, when travellers were stranded due to bad weather. The chef Joe Sheridan prepared them hot coffee, to which he added local whiskey, sugar and a layer of thick cream on top. The frozen passengers are said to have asked whether it was Brazilian coffee, and Sheridan replied that it was Irish coffee. Thus the name and the legend were born. From Ireland the drink later reached the United States, where it gained enormous popularity. It is a beautiful example of how a simple idea to warm up frozen people grew into a classic drunk around the world.
The secret of the floating cream
The hallmark of irish coffee is the layer of cream floating on the surface of the hot coffee. This effect is not accidental and requires technique. The cream must be lightly whipped, to a thick but still pourable consistency, and gently poured onto the top of the hot, sweetened coffee, ideally over the back of a spoon. The sugar in the coffee is there not only for taste but for density, because it helps keep the cream on the surface. This way you drink hot, strong coffee through a cool, creamy layer, which creates a unique contrast. The key is not to stir the drink but to drink it through the cream. It is a simple but striking trick that distinguishes a real irish coffee from ordinary coffee with whiskey and whipped cream.
The classic irish coffee recipe
A good irish coffee also rests on a few rules. The base is hot, strong, freshly brewed coffee, to which Irish whiskey and sugar, thoroughly dissolved, are added. Lightly whipped cream is gently poured on top so that it forms a separate layer. It is served in a handled glass so it does not burn the hand. The key is that the coffee is really hot and the cream cool, because the contrast of temperatures is part of the experience. The drink must not be stirred after the cream is added. On the choice of the Irish whiskey itself, which gives the drink a smooth, slightly fruity character, you can read more in the post on Irish whiskey. A good irish coffee is a harmony of hot coffee, alcohol, sweetness and cool cream.
The role of coffee quality
In both cocktails coffee is the foundation, not the background, so its quality translates directly into the taste of the drink. Weak, over-roasted or old coffee will give a bitter, flat drink that no alcohol can save. In an espresso martini what counts is good, fresh espresso with a nice crema, ideally from coffee of a distinct but not burnt profile. In irish coffee a strong, aromatic coffee works, one that can cut through the whiskey and cream. It is worth choosing coffee with notes that complement the alcohol, for example chocolate or nut. This is a good argument for not using just anything in cocktails, but a deliberately chosen coffee.

Other coffee cocktails
The espresso martini and irish coffee are only two of many coffee drinks. The bar world knows far more of them, from hot variants with various spirits to cold, milky cocktails. Classic variations of irish coffee replace the whiskey with other spirits, creating for example versions with rum or brandy. The espresso martini has spawned countless flavour variations, with the addition of spices, nut liqueurs or salt. The common denominator is always good coffee as a base and the right balance of sweetness, bitterness and alcohol. It is a field for experiment in which it is easy to find your own successful combinations. Coffee cocktails show that coffee is not only a morning ritual but also a full member of the world of mixology, able to shine after dark.
What it means in the glass
For the drinker, both cocktails are two different pleasures based on the same ingredient. The espresso martini is cold, velvety, coffee-forward and stimulating, with a smooth foam and a clear espresso character. Irish coffee is hot, creamy and warming, with a contrast of strong coffee and cool cream. In both the key is the quality of the coffee and the technique, because they decide whether the drink is elegant or bland. It is worth treating them as an opportunity to appreciate coffee in a new role, not only as a morning drink. If you like to experiment, try matching a coffee of a specific profile to the cocktail and see how it changes the whole. Coffee cocktails are proof that good coffee can shine as brightly in the evening as in the morning, in the company of alcohol.
The key points
The espresso martini and irish coffee are two classic coffee cocktails of opposite characters. The espresso martini, created around 1983 by Dick Bradsell in London, is a cold drink of fresh espresso, vodka, coffee liqueur and sugar, whose secret is the crema, which is why the espresso must be hot and fresh and the drink shaken vigorously. Irish coffee, created in 1943 at Foynes airport, is hot coffee with Irish whiskey, sugar and a layer of floating cream that must not be stirred. In both, coffee is the foundation, so its quality and freshness decide the taste. They are two different ways to appreciate coffee in the company of alcohol, one cold and elegant, the other hot and warming.
