Homemade Coffee Liqueur
This homemade liqueur has a balance of smooth coffee flavor, sweetness, and booziness. Start by making a batch of cold-brewed coffee, then stir in a brown-sugar simple syrup, aged rum, and half of a vanilla bean and let it infuse for 2 weeks. Pour the liqueur over ice to sip as is, add it to a creamy cocktail, or use it in desserts like a White Russian Milk Shake or Drunken Affogatos.
- 2 1/2 ounces coarsely ground coffee (about 3/4 cup)
- 2 1/4 cups water
- 1/2 cup packed dark brown sugar
- 1 cup aged rum
- 1/2 vanilla bean
1Place the coffee grounds in a 2-cup measuring cup or small pitcher, add 1 3/4 cups of the water, and stir to combine. Cover with plastic wrap and let steep at room temperature for at least 12 hours and up to 1 day.
2Line a fine-mesh strainer with a standard coffee filter and fit it over a medium bowl. Working in batches, slowly pour the coffee into the filter until all of the liquid has passed through the strainer (the coffee will pass through in a slow stream; don’t force it through); stop when you reach the solids at the bottom of the pitcher—don’t pour them in. Discard the grounds and the contents of the strainer. Transfer the coffee to a 1-quart container and set it aside.
3Place the remaining 1/2 cup of water and sugar in a small saucepan over high heat and bring it to a simmer, stirring to dissolve the sugar. Remove from the heat and let cool to room temperature, about 30 minutes.
4Add the cooled syrup and rum to the container with the coffee. Using a knife, split the vanilla bean in half lengthwise and scrape the seeds out of the bean, add both the seeds and pod to the coffee mixture (make sure the pod is submerged), and stir to combine. Tightly cover the container and let it sit at room temperature in a cool, dark place for at least 2 weeks, shaking once a week.
