The coffee not only brings a rich, roasted bitterness but also enhances the caramel and vanilla notes in the whiskey, creating a harmonious blend of flavors. Whether you’re looking for a new cocktail to impress your guests or a unique drink to enjoy on a quiet evening, the Dark Roast Whiskey Sour is sure to deliver.
This cocktail is versatile enough to be enjoyed year-round. In colder months, the warm, robust flavors of coffee and whiskey provide a comforting drink, while in the summer, its refreshing citrus notes and chilled presentation make it an excellent choice for warm evenings. It’s also a fantastic option for brunches, offering a caffeinated kick alongside the classic cocktail elements. Let’s dive into how you can create this delicious, sophisticated drink at home.
Ingredients
For the Cocktail:
- 2 oz (60 ml) bourbon or rye whiskey – Choose a high-quality whiskey with strong caramel or spice notes
- ¾ oz (22 ml) fresh lemon juice – Freshly squeezed for the best flavor
- ½ oz (15 ml) coffee syrup – Made from dark roast coffee and sugar (recipe below)
- ½ oz (15 ml) simple syrup – Adjust based on your sweetness preference
- 1 egg white (optional) – For a creamy, frothy texture
- Ice cubes – For shaking and serving
For the Coffee Syrup:
- ½ cup (120 ml) freshly brewed dark roast coffee – Cooled to room temperature
- ½ cup (100 g) granulated sugar – Dissolves to create a smooth syrup
- ¼ tsp vanilla extract – Adds depth and enhances the coffee flavor
Garnish:
- Luxardo cherry or maraschino cherry – For a sweet, elegant touch
- Orange twist – Adds a bright citrus aroma
- A few dashes of Angostura bitters (optional) – For added complexity
Preparation
Step 1: Make the Coffee Syrup
Start by brewing a strong cup of dark roast coffee. Let it cool to room temperature before proceeding. In a small saucepan, combine the cooled coffee and granulated sugar over medium heat. Stir continuously until the sugar has completely dissolved, which should take about 3-5 minutes. Remove the saucepan from heat and stir in the vanilla extract. Allow the syrup to cool completely, then transfer it to a sealed container. Store the syrup in the refrigerator, where it will keep for up to two weeks.
Step 2: Prepare Your Glassware
While you prepare the cocktail, chill your glassware to ensure the drink stays cold. Fill a coupe or rocks glass with ice water and set it aside. If you prefer a sweeter rim, you can lightly coat the edge of the glass with lemon juice and dip it into sugar before chilling.
Step 3: Mix the Cocktail
In a cocktail shaker, combine the bourbon or rye whiskey, fresh lemon juice, coffee syrup, simple syrup, and egg white if using. The egg white will give the drink a creamy texture and a beautiful frothy top. Begin with a dry shake, which means shaking the ingredients without ice, for about 15 seconds. This helps emulsify the egg white and create a smooth foam. After the dry shake, add ice cubes to the shaker and shake vigorously for another 15-20 seconds until the mixture is well-chilled.
Step 4: Strain and Serve
Discard the ice water from your chilled glass. Using a fine mesh strainer, double strain the cocktail into the glass. This ensures a smooth texture by removing any ice shards and bits of egg white. The result should be a silky, frothy drink with a rich, dark hue.
Step 5: Garnish
For the final touch, garnish your Dark Roast Whiskey Sour with a Luxardo cherry or maraschino cherry. If you prefer a citrusy aroma, express an orange twist over the drink by gently squeezing it to release the oils, then place it on the rim or drop it into the glass. For an added layer of flavor, consider adding a few dashes of Angostura bitters on top of the foam.
Variation
Spiced Dark Roast Whiskey Sour
Add a pinch of ground cinnamon or nutmeg to the coffee syrup while it’s simmering. This adds a warm, spiced note that pairs beautifully with the coffee and whiskey flavors.
Maple Coffee Whiskey Sour
Substitute the simple syrup with pure maple syrup for a richer, more complex sweetness. The maple flavor complements the coffee and adds a unique twist to the classic cocktail.
Smoky Dark Roast Whiskey Sour
Use a peaty Scotch whisky instead of bourbon or rye for a smoky, deep flavor profile. This variation adds an extra layer of complexity, perfect for those who enjoy smoky cocktails.
Decaf Version
For a caffeine-free version, simply use decaffeinated dark roast coffee to make the coffee syrup. You’ll still get the rich, roasted flavor without the caffeine kick.
Cooking Notes
When selecting your coffee, opt for a dark roast with bold, robust flavors. The coffee should have chocolatey, nutty, or caramel notes that will complement the whiskey. If you prefer a milder coffee flavor, you can use a medium roast instead.
The balance of sweetness and bitterness is key in this cocktail. Adjust the simple syrup and coffee syrup to your taste. If you prefer a sweeter drink, increase the simple syrup slightly. For a more bitter, coffee-forward profile, reduce the simple syrup or increase the coffee syrup.
If using egg whites, make sure they are fresh and of high quality. The dry shake is essential to properly emulsify the egg white and create the desired frothy texture. If you’re uncomfortable using raw egg whites, you can substitute with aquafaba, the liquid from canned chickpeas, which mimics the texture without altering the flavor.
Serving Suggestions
Serve the Dark Roast Whiskey Sour in a chilled coupe glass for a sophisticated presentation, or in a rocks glass over ice for a more casual feel. This cocktail pairs beautifully with dark chocolate, roasted nuts, or smoked meats, which enhance its rich, complex flavors.
It’s an excellent choice for after-dinner drinks, offering a perfect blend of coffee and whiskey to end the evening on a high note. It’s also a great addition to brunch menus, providing a caffeinated kick alongside classic brunch fare.
Tips
Use high-quality whiskey for the best flavor. A rich, full-bodied bourbon or spicy rye whiskey will elevate the cocktail and complement the coffee notes. Always use freshly squeezed lemon juice for the brightest, freshest flavor.
Shaking the cocktail properly is crucial. The dry shake helps incorporate the egg white for a smooth, frothy texture, while the second shake with ice chills the drink and dilutes it slightly for balance.
Experiment with different bitters to add complexity. Chocolate bitters or coffee bitters can enhance the flavors and add unique twists to the cocktail.
