The best coffee liqueur for an Espresso Martini is the one that tastes of coffee once it is shaken with ice, espresso and a spirit. That sounds obvious. It rules out more bottles than you would think. Here is what actually matters, how the UK options compare, and the recipe we use.
Why the liqueur matters more than the vodka
An Espresso Martini is three things in roughly equal measure: a spirit, a coffee liqueur, and a shot of espresso. The espresso is the one everyone worries about. The vodka is the one everyone spends money on. The liqueur is the one that decides how the drink tastes, because it is the only ingredient bringing both sugar and a second layer of coffee.
Shake the drink and the espresso's aromatics fade fast. What is left after twenty seconds of ice is the liqueur's coffee, the liqueur's sugar, and whatever the base spirit adds. If the liqueur is mostly sugar with a coffee flavouring, you get a sweet brown drink with a nice foam. If the liqueur is a real coffee extraction, you get a drink that still tastes of coffee at the bottom of the glass.
What to look for
Real coffee, and a named one. The label should tell you what the coffee is and how it was extracted. "Natural flavourings" is a warning sign. Cold brew is the method to look for. It pulls the chocolate and caramel out of the bean without the acidity and bitterness that hot extraction leaves behind, and it survives being shaken far better.
Less sugar than you expect. The espresso brings its own bitterness, so the liqueur needs some sweetness to balance it. But the mass-market bottles carry so much sugar that the drink ends up cloying, which is why so many recipes tell you to add syrup and then complain the result is sickly. A drier liqueur lets you control the sweetness yourself.
A base spirit that contributes something. Most coffee liqueurs sit on neutral grain spirit, which is fine and tastes of nothing. A few use rum, which adds warmth. Fewer still use a grape spirit like Armagnac or Cognac, which adds fruit and depth underneath the coffee. In an Espresso Martini, where the vodka is also neutral, a liqueur with a characterful base is the only place any complexity is going to come from.
Enough strength to hold up. Below about 20% ABV, a liqueur dilutes into the drink and disappears. Between 20% and 25% it holds its shape. Above that, you are effectively adding a second spirit and the drink gets hot.
After twenty seconds on ice, the espresso has faded. What is left is the liqueur.
Five UK options, honestly
Kahlúa (16% ABV, around £17). The default, and the reason most home Espresso Martinis taste the way they do. Rum base, a lot of sugar, coffee flavouring rather than a coffee extraction. It makes a drinkable Espresso Martini. It does not make a good one. If this is what you have, skip the sugar syrup entirely.
Tia Maria (20% ABV, around £18). Drier than Kahlúa, with a vanilla note and a Jamaican rum base. A genuine step up for the money and the best of the supermarket options. Still a flavouring-led liqueur rather than a coffee-led one.
Mr Black (23% ABV, around £30). The bottle that changed the category. Australian, cold brew coffee on a wheat vodka base, and unapologetically bitter. It makes a sharp, grown-up Espresso Martini. Some people find it too austere without a little syrup. If you like your coffee black, this is the benchmark.
Conker Cold Brew (25% ABV, around £28). Dorset-made, cold brew on a neutral base, cleaner and rounder than Mr Black. A good, honest coffee liqueur that sits comfortably in the middle of the field.
Elusa Coffee Liqueur (21.5% ABV, £35). Ours, so weigh what follows accordingly. The difference is the base. Instead of neutral spirit it is built on Blanche Armagnac, an unaged grape spirit from a family estate in Gascony, and the coffee is Dark Side cold brew, a dark roast of Central American and Asian beans, brewed for 18 hours at 4°C and filtered twice. Both ingredients hold Great Taste 2-star awards in their own right, and the liqueur took a Great Taste star of its own in 2026. In the glass that means chocolate and caramel from the coffee, fruit and warmth from the Armagnac underneath, and less sugar than the mass-market bottles.
If money is no object and you want the sharpest possible drink, Mr Black. If you want a drink with something going on beneath the coffee, ours. If you are on a budget, Tia Maria over Kahlúa every time. There is a longer comparison in our guide to the best coffee liqueurs in the UK.
The recipe we use
The proportions below are the ones on our Espresso Martini page. No sugar syrup is listed because the liqueur carries enough sweetness on its own; add 5ml if your espresso is particularly bitter.
Espresso Martini
- 35ml vodka, or Elusa Blanche Armagnac for a drink with more depth
- 25ml Elusa Coffee Liqueur
- 30ml freshly pulled espresso, cooled for a minute
- Three coffee beans, to garnish
Chill a coupe. Add everything to a shaker, fill it with ice, and shake hard for a full fifteen seconds. Hard matters: the crema on top comes from the espresso's oils being beaten into foam, not from any ingredient you add. Double strain into the coupe and float the beans on the foam. Drink it within a few minutes, before the foam settles.
If you want the drink without the sweetness of a liqueur at all, that is a different recipe, covered in Espresso Martini without Kahlúa.
Three mistakes that ruin a good liqueur
Instant coffee. It foams beautifully and tastes of nothing. If you have no espresso machine, a strong moka pot coffee or a shop-bought cold brew concentrate both work. Instant does not.
Hot espresso straight into the shaker. It melts the ice before you have started shaking, so the drink is over-diluted and under-chilled. Pull the shot first, then chill the glass, then build the drink.
Too much of everything. The drink is small on purpose. A 90ml pour into a coupe is right. Doubling it into a rocks glass turns a cocktail into a coffee milkshake.
The short version
The best coffee liqueur for an Espresso Martini is one made from actual coffee, with restraint on the sugar and a base spirit that adds something. Kahlúa is fine, Tia Maria is better, Mr Black is the sharpest, and ours is the one with Armagnac underneath. Whichever you pick, shake it harder than feels reasonable.
