Espresso Liqueur Recipe

Brew and concentrate

Brew 2 cups of very strong espresso. If you don't have an espresso machine, brew a strong dark coffee (use about double the normal grounds). While still hot, stir in 1 tablespoon instant espresso powder if using to intensify the flavor. Allow the coffee to cool to near room temperature (about 30–45 minutes).

Make simple syrup

Combine 1.5 cups granulated sugar and 3/4 cup water in a small saucepan. Heat over medium, stirring constantly until the sugar fully dissolves and the mixture just reaches a gentle simmer. Do not boil vigorously. Once clear and slightly thickened, remove from heat and let cool to warm (10–15 minutes).

Optional caramel note

For a deeper flavor, you may brown the sugar slightly: heat sugar alone until it begins to caramelize, then carefully add the water (stand back — it will steam) and stir until smooth. Cool before proceeding.

Mix base ingredients

In a clean, heatproof pitcher or bowl, combine the cooled espresso and the cooled sugar syrup. Stir until homogenous.

Add alcohol and flavor

Pour in 2 cups vodka and 1/4 cup dark rum or brandy (if using). Add the split vanilla bean (scrape seeds into the mixture and toss in the pod) or 1 tablespoon vanilla extract. Add 1 tablespoon coffee beans and a pinch (about 1 teaspoon) of salt to amplify flavors. Stir to combine.

Initial rest

Cover the mixture and let it rest at room temperature for 24 hours to marry flavors, stirring once or twice. If you prefer a stronger coffee profile, steep up to 48 hours, then strain.

Strain and clarify

After infusion, strain the liqueur through a fine-mesh sieve lined with cheesecloth or a coffee filter to remove grounds, vanilla pod pieces, and beans. If the liquid is cloudy, refrigerate for several hours and decant off any sediment, or filter again through a paper filter.

Adjust sweetness and proof

Taste the liqueur. If it's too strong or bitter, add a little more simple syrup (in 2–4 tablespoon increments). If too sweet, add a splash more vodka. Adjust until balanced.

Bottle and age

Transfer the strained liqueur to sterilized bottles or jars, seal tightly, and store in a cool, dark place. For best flavor, age at least 2 weeks before using; flavors will continue to meld and mellow for up to 3 months. Refrigeration is optional — it may thicken slightly when chilled.

Serve suggestions

Serve neat over ice, in espresso martinis, poured over ice cream, or used in cocktails. Shake or swirl before serving if any separation has occurred. Garnish with a few whole coffee beans if desired.
