Ensure your espresso is freshly brewed and cooled to room temperature.

Chill your martini glass in the freezer or fill with ice water.

In a cocktail shaker, combine vodka, coffee liqueur, cooled espresso, and simple syrup.

Fill the shaker generously with ice.

Secure the lid and shake vigorously for 15-20 seconds, until the shaker is frosty and a thick foam forms.

Empty the chilled martini glass of any ice water.

Double-strain the cocktail into the prepared martini glass to ensure a smooth texture.

Garnish with three whole coffee beans floated on top of the foam.
