A proper espresso martini recipe comes down to one detail, the foam. You get a thick, stable foam on top of an espresso martini by shaking freshly pulled, hot espresso with the other ingredients for 10 to 15 seconds and straining it fast into a chilled glass before that foam has a chance to collapse. Skip any of those steps and you end up with a flat, watery drink that tastes thin and looks unfinished, whether it is served behind a bar or poured at a home counter.

Most failed attempts share the same causes, espresso that has sat too long, a half-hearted shake, or stale beans with no crema left to give. This guide works through the exact espresso martini recipe professional bartenders rely on, the ingredients that keep it balanced, and the technique that builds that signature foam every time. It also covers coffee selection, equipment for busy service, and how bars, caterers and event teams scale the drink without losing quality. We have been a family-run supplier of coffee equipment and beans since 1993, and the equipment guidance below draws on that experience. Read on for the measurements, the method, and the fixes for when foam refuses to form.

Key Takeaways

  • The classic recipe uses 50ml vodka, 25ml fresh espresso, 15ml coffee liqueur and 10ml simple syrup, shaken hard over ice.
  • Espresso needs to go from machine to shaker within a minute or two, since any longer and the crema that builds the foam is already gone.
  • A hard 10 to 15 second shake builds the foam head, not any single ingredient or brand of vodka.
  • Well-maintained espresso equipment matters more than premium spirits once you are pouring dozens of these drinks a night.
  • Bars and events need pre-batched components and trained staff to keep quality the same from the first drink to the last.

What Is An Espresso Martini?

An espresso martini is a shaken cocktail built from vodka, fresh espresso and coffee liqueur, and despite its name it contains no gin or vermouth at all. Bartender Dick Bradsell created the drink in 1980s London, reportedly after a customer asked for something that would wake her up and keep the night going, a history detailed in this espresso martini recipe guide, and the format has barely changed since.

The drink has become a fixture on coffee shop and bar menus because it sits between two cultures that share a customer base, people who want good coffee and people who want a well-made cocktail. For hospitality venues, office events and home entertaining alike, it works equally well as a dessert alternative or an evening showpiece drink. As with any cocktail, serve it responsibly: a single drink contains a double measure (50ml) of vodka as well as a shot of espresso.

Espresso Martini Ingredients You Need

Every espresso martini recipe worth repeating starts with four ingredients measured properly rather than poured by eye, and each one does a specific job in the glass. Get the ratio wrong in either direction and the drink tips into something too bitter, too sweet or too thin, which is why professional bars treat these measurements as fixed rather than flexible.

  • Vodka (50ml) forms the spirit base and should be clean and neutral rather than heavily flavoured, since its job is to carry the other ingredients without competing with the coffee. Mid-range and premium bottles both work well here, and the main requirement is a smooth finish with no harsh alcohol burn.
  • Fresh espresso (25ml) is the heart of the drink and needs to be pulled right before mixing, ideally within a minute or two of hitting the shaker. It should show a full, dark crema on top, since that crema is doing most of the work in building the drink’s foam later on.
  • Coffee liqueur (15ml), typically Kahlúa, adds sweetness and a second layer of coffee flavour that rounds out the sharper edges of the espresso. Some bars swap in Tia Maria or Mr Black for a different balance of sweetness to coffee intensity.
  • Simple syrup (10ml), made from equal parts sugar and water, balances the bitterness of the espresso without masking it. Bartenders sometimes adjust this measure up or down depending on how sweet their chosen coffee liqueur already is.

Which Coffee Works Best For An Espresso Martini?

Medium to dark roasts with chocolate, caramel or nutty notes generally work best, since these flavours stand up against the vodka and the sweetness of the coffee liqueur rather than getting lost behind them. Lighter, more acidic roasts can throw the drink’s balance off and introduce an unwelcome sourness.

Freshness matters just as much as roast level, since stale beans produce a thin shot with little crema and almost no foam potential at all. Our coffee beans range includes espresso blends known for a rich crema, giving bars and home baristas a dependable base for the espresso shot that anchors this cocktail.

How To Make An Espresso Martini Step By Step

Making an espresso martini properly follows a short, fixed sequence rather than a flexible process, and skipping or reordering steps is where most drinks go wrong. The method below reflects how professional bars build the drink from a cold glass through to the floated coffee bean garnish, and it works equally well for a single home-made cocktail or a run of drinks during a busy shift. Getting comfortable with this sequence turns the recipe below from a list of measurements into a drink you can repeat with confidence.

The Classic Recipe (Table)

The table below sets out the standard measurements used across most professional bars, scaled for a single serving.

Ingredient Measurement
Vodka 50ml
Fresh espresso 25ml
Coffee liqueur 15ml
Simple syrup 10ml
Ice Fill shaker halfway
Garnish 3 coffee beans

For batch service, multiply each measurement by the number of drinks needed, though espresso should still be pulled fresh for each round rather than batched in advance.

Step-By-Step Method

Start by chilling your martini or coupe glass in the freezer, then pull a fresh espresso shot as your final preparation step so it reaches the shaker while still hot. Add the vodka and coffee liqueur to a shaker filled halfway with ice, followed by the simple syrup, then pour in the hot espresso last so its heat begins working into the ice straight away.

Seal the shaker and shake hard for 10 to 15 seconds, which chills the drink and builds the foam at the same time. Strain through a Hawthorne strainer into the chilled glass, pouring steadily so the foam settles on top rather than breaking apart, then float three coffee beans on the surface and serve within half a minute while the foam is still at its thickest.

How Do You Get The Perfect Espresso Martini Foam?

The foam on top of a well-made espresso martini comes from two things working together: the natural crema in fresh espresso and the physical agitation of a hard shake. Neither alone produces a thick foam. A great espresso with no shaking still falls flat, and a long shake with stale, crema-less espresso produces almost nothing on top either. The shaking motion forces tiny air bubbles into the mixture, and compounds from the fresh espresso help those bubbles hold their shape instead of collapsing straight back into the liquid.

  • A dry shake, where all the ingredients are shaken without ice for around 10 seconds before ice is added for a second, harder shake, is a technique many bartenders use to build a thicker foam than a single shake alone. This two-stage approach gives the mixture more time to trap air before the ice starts diluting and chilling it.
  • Pasteurised egg white (around 15ml) is sometimes added for an even denser, longer-lasting foam, a technique borrowed from classic sour cocktails. Aquafaba, the liquid from tinned chickpeas, gives a similar result for venues or customers wanting a vegan option without sacrificing foam quality.

Common Foam Mistakes To Avoid

The two most common causes of a disappointing foam are espresso that sat too long before shaking and a shake that is too gentle or too short. Even a minute or two of delay lets the crema break down, while anything under 10 seconds of hard shaking rarely builds enough air into the mixture. A poorly maintained grinder producing uneven extraction causes the same problem from the start.

Equipment You Need For Consistent Results

Consistent results from one espresso martini to the next depend on a short list of tools rather than anything exotic, and the quality of that equipment matters more as volume increases. A home bar can get away with basic versions of each item, but a busy venue needs tools built for repeated, hard use night after night.

  • A Boston shaker holding at least 750ml gives enough room for ice and liquid to move properly during a hard shake, which matters for foam quality as much as it does for chilling. Cheap, flimsy shakers can dent or seize up under repeated use during a busy service.
  • A jigger measuring both 25ml and 50ml keeps pours accurate from one drink to the next, which matters for flavour balance and for training new staff quickly. Free-pouring by eye introduces variation that is hard to spot until a customer complains.
  • A Hawthorne or fine mesh strainer separates the drink from the ice while keeping the foam intact on top, and a fine mesh version catches any small espresso particles for a cleaner finish.
  • A reliable espresso machine is the single biggest factor in foam quality, since every other step depends on a good shot with a proper crema. A machine with clean group heads and correctly maintained seals produces that shot consistently, while a poorly serviced one will not, regardless of how good the beans are.
  • Pre-chilled martini or coupe glasses, kept in the freezer until needed, keep the finished drink cold and help the foam hold its shape for longer after it is poured.

Choosing The Right Espresso Setup For Volume Service

Venues pouring a lot of espresso martinis across a shift need equipment built for that pace rather than a machine designed for occasional home use. Self-serve and bean-to-cup machines built for dependable, repeated extraction reduce the gap between a trained barista’s shot and one pulled by newer staff during a rush, which matters when every drink needs the same crema to build a proper foam.

We supply commercial espresso machines and bean-to-cup coffee machines built for this kind of repeated, high-volume use, alongside espresso grinders that keep particle size consistent shot after shot. For bars, hotels and event caterers scaling up a cocktail offering, our espresso machine and grinder ranges are worth reviewing before committing to a single setup.

Espresso Martinis For Bars And Events: Scaling Up

Serving espresso martinis at volume, whether across a full bar shift or a one-off event, introduces problems that never come up when making a single drink at home. Staff need a written recipe they can follow without guessing, ingredients need to be pre-measured where possible, and someone needs to be responsible for tasting drinks periodically to catch any drift in quality before customers notice it.

  • Pre-batch the vodka, coffee liqueur and simple syrup into a single bottle ahead of service, so staff only need to add fresh espresso and ice at the point of shaking. This cuts preparation time considerably during a rush without touching the one ingredient that has to stay fresh at the moment of pouring.
  • Train every member of staff on the same recipe, pour amounts and shake duration, using a written card behind the bar rather than relying on memory. Consistency across different staff members is what keeps repeat customers ordering the same drink with confidence, event after event.
  • Keep a buffer stock of beans, coffee liqueur, syrups and spare parts for the espresso machine on site during busy periods, since running out mid-service or losing a machine to a minor fault can stall drink service for the rest of the night.

Supporting Equipment: Syrups, Grinders And Maintenance

Flavour variations such as a vanilla or salted caramel espresso martini rely on quality syrups rather than improvised substitutes, and keeping a small range on hand lets a venue offer variety without a new ingredient list for every drink. Our coffee syrup range includes vanilla, salted caramel, hazelnut and sugar-free options, covering most of the variations bars and cafés want on a seasonal menu.

Beyond ingredients, keeping espresso machines and grinders running during busy periods depends on dependable supply and fast servicing when something breaks. We deliver from our warehouse in Eastbourne and use our own engineers for installation and repairs, with free next-working-day delivery on orders over £69 ex VAT to mainland UK.

A good espresso martini is only as good as the shot underneath it. Get the coffee right, and the rest of the recipe just falls into place.

Putting It All Together

Three things separate a forgettable espresso martini from a properly made one, fresh espresso pulled right before shaking, measurements followed precisely rather than estimated, and a hard 10 to 15 second shake that builds the foam rather than just chilling the drink. Get those three right consistently and every other detail, from coffee choice to garnish, becomes a matter of preference rather than correction.

Whether you are running a coffee shop considering an evening cocktail menu, catering an event, or perfecting the drink at home, the equipment behind the espresso shot matters as much as the recipe itself. Our coffee beans and espresso machine ranges are worth a look, or call 0800 442299 for guidance on building a setup that holds up under regular use.

Frequently Asked Questions

Can I Make An Espresso Martini Without An Espresso Machine?

Yes, a moka pot, stovetop maker or strong French press concentrate can substitute, though none match the crema a pressurised espresso shot produces. Expect thinner foam as a result, so an espresso machine remains the better option for a proper, thick head.

Why Does My Espresso Martini Not Have Enough Foam?

The usual causes are espresso that sat too long before shaking, a shake that was too short or too gentle, or stale beans with no crema-forming oils left. Fix the timing and shake duration first, since those two factors account for most flat results.

What Is The Best Coffee Liqueur For An Espresso Martini Besides Kahlúa?

Tia Maria gives a creamier, softer profile, while Mr Black leans into stronger coffee flavour with less added sweetness. Either works well in the classic recipe, with the choice mostly coming down to how sweet or coffee-forward you want the drink.

How Long Does An Espresso Martini Stay Good After It’s Made?

It should reach the customer within about 30 seconds of straining, since the foam starts breaking down and the drink begins warming almost immediately once it leaves the shaker. There is no practical way to hold a finished cocktail and still serve it at its best.

Can Espresso Martinis Be Batch-Prepared For Large Events?

The vodka, coffee liqueur and simple syrup can be pre-batched into one bottle ahead of time, which speeds up service considerably. Espresso still needs to be pulled fresh and added just before each shake, since that is the ingredient that builds the foam.

What’s The Difference Between An Espresso Martini And A Regular Martini?

A regular martini is built from gin or vodka and vermouth, with no coffee involved at all. An espresso martini swaps that formula entirely, using vodka, fresh espresso and coffee liqueur instead, which makes it a martini in name only.
