Espresso Martini

• 30 ml
  fresh espresso pulled fresh, cooled to room temperature — do not refrigerate
• 40 ml
  vodka clean and neutral — Ketel One, Grey Goose
• 20 ml
  coffee liqueur Kahlúa (classic) or Mr Black (more coffee-forward)
• 10 ml
  simple syrup optional if using Kahlúa, which is already sweet
• plenty
  ice vigorous shaking with cold ice creates the foam
• 3
  coffee beans as garnish — said to represent health, wealth, and happiness

1. 1

   Pull a fresh espresso and allow to cool to room temperature, 10–15 minutes. This is non-negotiable — hot espresso melts the ice and the drink will be warm and diluted.

   A quality espresso has three layers: crema (reddish-brown emulsified CO2 and coffee oils), body (dark liquid), and heart (very dark, concentrated liquid). The crema should be intact but the espresso must be at room temperature before shaking. The cooling process concentrates the oils slightly and allows the CO2 to partially off-gas — this dissolved CO2 is what creates the thick, persistent foam in the finished cocktail. Refrigerating the espresso causes the oils to separate and the foam potential decreases.
2. 2

   Chill a martini or coupe glass in the freezer.

   Technique Depth

   A frozen glass (−18°C) versus a room-temperature glass (20°C) is the difference between foam that holds for 8–10 minutes and foam that collapses in 60 seconds. The extreme chill sets the espresso oil foam on contact — the rapid temperature drop stabilises the air-liquid interface in the foam structure. This single step separates a technically correct espresso martini from a mediocre one.
3. 3

   Combine espresso, vodka, coffee liqueur, and simple syrup in a cocktail shaker.

   Technique Depth

   The ratio of espresso to spirits determines whether this is a coffee drink with alcohol or an alcohol drink with coffee. At 30ml espresso to 60ml combined spirits, coffee dominates the flavour. Mr Black (40% ABV, very coffee-forward) produces a drier, more bitter, coffee-centric result. Kahlúa (20% ABV, sweeter, with vanilla notes) produces a more balanced, dessert-leaning result. The simple syrup may be omitted entirely when using Kahlúa.
4. 4

   Add plenty of ice. Shake vigorously for a full 15 seconds — longer than you think. The vigour creates the foam.

   Technique Depth

   The vigorous shaking simultaneously chills the liquid, creates micro-emulsification, and mechanically generates the foam. The espresso contains proteins (primarily chlorogenic acid complexes) and lipids that behave like egg white proteins when agitated — they unfold and form a stable air-liquid interface under mechanical force. 15 seconds is the minimum; 20 seconds produces a measurably superior foam. The shaking force should be maximal, not moderate.
5. 5

   Double-strain immediately into the chilled coupe: use both the shaker strainer and a fine mesh strainer.

   Technique Note ↓
   Technique Depth

   The cocktail shaker strainer alone cannot remove ice chips smaller than 2–3mm. Fine mesh straining removes all chips, which would otherwise puncture the foam surface as they melt. The double-strain pours the cold liquid through the fine sieve at the last moment, so the foam arrives at the glass surface intact rather than broken by the filter. Speed matters — the foam begins to degrade within 30 seconds of leaving the shaker.
6. 6

   The foam should be thick and persistent. Garnish with three coffee beans in a triangle. Serve immediately.

   Technique Depth

   The three-bean arrangement traces back to Venetian custom, where three grains of coffee represent salute (health), soldi (money), and fortuna (luck). The beans must be placed on the foam without breaking the surface — place gently, do not drop from height. The foam has a finite life; serve within 2 minutes. A thick, caramel-coloured, persistent foam that holds the weight of three coffee beans is the quality standard.

Shake hard and long — 15 seconds minimum, 20 seconds for confidence. The foam is the product of violent aeration of coffee proteins in the freshly pulled espresso. Speed is critical: the espresso must be used within 30 seconds of pulling. After that, the crema separates, the proteins begin to break down, and the foam is compromised before the shaker is picked up.

• 1. Freshly pulled double espresso — 30 seconds old maximum. The crema is the foam source; stale espresso has no foam.
• 2. Kahlúa (the original) or Mr Black (Australian, more assertive coffee character, less sweet).
• 3. Ketel One or Grey Goose vodka — a neutral spirit that carries coffee rather than competing with it.
• 4. Three coffee beans as garnish, placed precisely — tradition, not decoration. Bradsell placed them himself on the first drink.
• 5. No additional sugar syrup if the liqueur is already sweet enough. Taste the Kahlúa first.

• The foam should be fine-grained and matt, not coarse bubbles.
• The colour: dark brown, uniform, not pale.
• A sip should deliver cold bitterness immediately, followed by warmth from the spirit, sweetness last.

• Vietnamese egg coffee (cà phê trứng) — whipped egg yolk foam over strong coffee. Different structure, same foam-on-coffee principle.
• Irish coffee — lightly whipped cream floated on hot coffee with whiskey. Same layered architecture, served hot.
• Japanese Kyoto iced coffee — pour-over directly onto ice, maximising crema preservation. Different delivery, same commitment to fresh extraction.
