Step 1

Add demerara sugar and water to a small saucepan. Cook over medium heat, stirring occasionally, just until all the sugar has dissolved, about 2 minutes.

Step 2

Allow the mixture to cool in the saucepan.

Step 3

Add vodka, espresso, coffee liqueur, and demerara sugar syrup to a cocktail shaker filled partway with ice.

Step 4

Shake until well-chilled and foamy, about 15 seconds. Strain into six, 2 ounce (60 ml) shot glasses.

Step 5

Optionally, garnish each shot with a coffee bean.
