In 2025, with the surge in home mixology and a growing interest in natural, small-batch alternatives, DIY coffee liqueur is more popular than ever. Whether you want to gift it during the holidays or enjoy a splash in your after-dinner coffee, this homemade recipe offers depth, smoothness, and versatility.
What Is Coffee Liqueur?
Coffee liqueur is a sweet, coffee-flavored alcoholic beverage typically made from brewed coffee or espresso, sugar, and a spirit base like vodka, rum, or brandy. The final product is syrupy, aromatic, and slightly bitter with a pronounced coffee taste and warm finish.
Store-bought versions often contain artificial additives and preservatives. By making your own, you control the sweetness, strength, and flavor profile—creating a liqueur that reflects your personal taste.
Why Make Coffee Liqueur at Home?
There are several good reasons to try making coffee liqueur at home:
- It’s cost-effective compared to premium bottled brands
- You can choose the quality and origin of your coffee and alcohol
- It’s a fun DIY project with delicious results
- It makes a thoughtful homemade gift
- You can adjust sweetness and strength to suit your preference
Ingredients You’ll Need
Here’s a simple list of what you’ll need to make about 750ml to 1 liter of coffee liqueur.
- 1 cup of freshly brewed strong coffee or ½ cup espresso
- 1 cup granulated sugar or brown sugar (for a richer taste)
- 1 cup water
- 1 tablespoon vanilla extract or one vanilla bean
- 1.5 to 2 cups of vodka (or dark rum for deeper flavor)
Optional ingredients:
- A pinch of cinnamon or cocoa powder
- A few crushed cardamom pods for a spiced twist
- Orange zest for citrus notes
Step-by-Step: How to Make Coffee Liqueur at Home
Step 1: Brew Strong Coffee
Start by brewing a strong cup of coffee. You want a bold, rich brew, so use a dark roast and double the amount of grounds you’d normally use. If you have an espresso machine or AeroPress, use those for a more concentrated result. Let the coffee cool completely.
Step 2: Make the Sugar Syrup
In a saucepan over medium heat, combine the sugar and water. Stir until the sugar is fully dissolved and the mixture becomes slightly thick, about 3 to 5 minutes. Remove from heat and let it cool.
If you’re using a vanilla bean, split it and add it to the syrup while it’s still warm to infuse flavor.
Step 3: Combine Ingredients
In a clean glass jar or bottle, combine the cooled coffee, cooled sugar syrup, vanilla extract or bean, and vodka or rum. Shake gently to mix.
For a stronger kick, go for 2 cups of alcohol. For a smoother, sweeter liqueur, use 1.5 cups.
Step 4: Let It Infuse
Seal the bottle or jar and let the mixture infuse in a cool, dark place for at least 7 days. Shake it once daily. You can also let it steep longer—up to 3 weeks—for a more developed flavor.
Step 5: Strain and Store
If you used a vanilla bean or added any spices, strain the mixture through a cheesecloth or coffee filter. Pour the filtered liqueur into a clean, sealable bottle. Store in the fridge or a cool cupboard.
Your homemade coffee liqueur will stay good for up to 3 to 6 months, though most people finish it long before that.
Flavor Variations to Try
The beauty of DIY coffee liqueur is how easily you can experiment with flavor. Try some of these variations:
Mocha Liqueur
Add 2 tablespoons of unsweetened cocoa powder to the syrup for a chocolatey depth.
Spiced Liqueur
Add whole cinnamon sticks, star anise, or clove during the infusion phase.
Coconut Coffee Liqueur
Use coconut sugar and add a splash of coconut extract or rum for a tropical twist.
Bourbon Coffee Liqueur
Swap vodka with bourbon for smoky, caramel undertones.
How to Use Homemade Coffee Liqueur
Once ready, your homemade coffee liqueur can be enjoyed in several ways:
- On the rocks as a post-dinner sipper
- Mixed into coffee for a spiked caffeine kick
- In desserts, drizzled over ice cream or used in tiramisu
- Cocktails, like a classic Black Russian or Espresso Martini
