You’re tired. It’s 10:00 PM on a Friday. You want a drink that feels sophisticated, something that bites back a little, but you also don’t want to be asleep before the second act of whatever movie you just rented. Enter the bourbon espresso old fashioned. It’s basically the "adult" version of the espresso martini, minus the shaker tins and the foam that looks like dish soap.
Honestly, the drink is a bit of a contradiction. Bourbon is heavy. It’s oaky, vanilla-forward, and usually makes you want to curl up by a fire. Espresso is the opposite. It’s jittery. It’s sharp. But when you marry them with a bit of sugar and bitters, something weird happens—they actually start to like each other. The bitterness of the coffee cuts through the corn-heavy sweetness of the bourbon, and the result is a cocktail that tastes like expensive dark chocolate and expensive leather.
Most people mess this up. They use cheap instant coffee or they drown the spirit in too much simple syrup because they're afraid of the bite. Don't do that. If you’re going to make a bourbon espresso old fashioned, you have to respect the ingredients, or you’re just drinking cold, boozy breakfast.
The Science of Why Coffee and Corn Work
There is a real chemical reason why this pairing works so well. Bourbon is aged in charred new American oak barrels. During that aging process, the wood releases compounds like vanillin (which smells like vanilla) and guaiacol (which gives that smoky, woody aroma). Coffee beans undergo the Maillard reaction during roasting, creating similar smoky and toasted flavor profiles.
When you sip a bourbon espresso old fashioned, your brain is picking up on those shared aromatic molecules. It’s a bridge.
Let's talk about the espresso part for a second. If you don't have a high-end machine, don't panic. You can use a moka pot or even a very strong cold brew concentrate (like Stumptown or a homemade 24-hour steep). The key is the concentration. You want the "oiliness" of the coffee to provide a mouthfeel that matches the viscosity of the whiskey. A watery drip coffee will ruin the drink. It’ll just taste like a sad, diluted mess.
Choosing Your Bourbon
Not all bourbon is created equal for this specific task. If you pick something with a very high rye content—think Bulleit or Old Grand-Dad—the spice might clash with the acidity of the coffee. It can get a little "noisy" on the palate.

Instead, look for a wheated bourbon or something with a classic, high-corn mash bill. Maker’s Mark is a solid, accessible choice because the wheat makes it softer and sweeter. If you want to go higher end, Woodford Reserve Double Oaked is incredible here. Because it’s aged in a second barrel that has been heavily toasted, it carries massive notes of caramel and dark chocolate that feel like they were literally made to be stirred with espresso.
Buffalo Trace is another winner. It has a balanced profile that doesn't try to fight the coffee for dominance. You want a partner, not a competitor.
The Ritual of the Build
Forget the cocktail shaker. You aren't making a sour. You are making an Old Fashioned variant. That means you stir. Stirring keeps the texture silky and prevents the drink from getting too much aeration, which would dull the rich flavors of the bourbon.
Start with your sweetener. A standard simple syrup works, but if you want to be a pro, use demerara syrup. It’s darker, unrefined, and has a molasses undertone that bridges the gap between the bean and the barrel. Use about a quarter ounce.
Add your bitters. Two dashes of Angostura are mandatory. If you want to get fancy, add one dash of chocolate bitters or orange bitters. Orange is actually the secret weapon here. The citrus oil brightens the whole drink and prevents it from feeling too heavy or "muddy."
Now, the espresso. You need it to be chilled or at least room temperature. If you pour a hot shot of espresso directly onto ice with your bourbon, the ice will flash-melt. Dilution is the enemy of a good bourbon espresso old fashioned. Pull your shot, let it sit for five minutes, or put it in the fridge while you prep everything else.

The Stir Matters
Fill a mixing glass with plenty of ice. Big cubes. Pour in two ounces of your chosen bourbon and one ounce of the espresso. Stir for about 30 seconds. You want the outside of the glass to feel cold to the touch. This isn't just about temperature; it's about getting just enough water from the melting ice to open up the aromatics of the whiskey.
Common Mistakes People Make (and how to fix them)
- Using flavored syrups: Just don't. Vanilla syrup or caramel syrup makes this taste like a Starbucks drink that fell into a liquor cabinet. Keep it classic with demerara or plain sugar.
- The Wrong Garnish: A maraschino cherry is fine for a standard Old Fashioned, but here, it feels out of place. Use a wide swath of orange peel. Express the oils over the top of the glass—twist it until you see the tiny spritz of oil land on the surface of the drink—and then drop it in. The aroma of the orange peel as you take a sip is half the experience.
- Bad Ice: If you're using those tiny, cloudy ice cubes from your freezer's automatic dispenser, they're going to melt in three minutes. Your drink will be watery. Invest in a $5 silicone mold for large clear spheres or cubes. It makes a massive difference in how the drink holds its integrity over twenty minutes.
Why This Drink is Taking Over Bars
You’ve probably noticed the bourbon espresso old fashioned appearing on more menus lately. It’s part of a broader trend where people are moving away from the "sugar bomb" cocktails of the early 2000s and toward drinks that offer depth and a bit of a functional kick.
Bartenders love it because it’s a "bridge" drink. It appeals to the person who usually drinks coffee all day and the person who treats bourbon like a religion. It’s also incredibly photogenic, though that shouldn't be the reason you make it. The dark, mahogany hue of the liquid against a large clear ice cube looks classic.
According to spirits historians and enthusiasts, the Old Fashioned itself is the "original" cocktail. Adding coffee isn't some new-age sacrilege; it's a natural evolution. People have been adding spirits to coffee for centuries (think Irish Coffee or the Venetian Caffè Corretto). This is just the cold, refined version of that tradition.
The Caffeine Factor
Let’s be real for a second. Mixing caffeine and alcohol is a specific choice. It produces a "wide-awake drunk" feeling that can be fun, but you should be mindful of it. A single shot of espresso has about 63mg of caffeine. That’s enough to keep you up if you’re sensitive to it. If you love the flavor but need to sleep, a high-quality decaf espresso works surprisingly well. The flavor profile is 95% the same, especially when diluted with bourbon and bitters.
Practical Steps to Mastering the Drink

First, chill your glassware. Put your rocks glass in the freezer for ten minutes. A cold glass keeps the ice from melting too fast. Second, pull your espresso shot first so it has time to lose its heat. While that’s happening, measure your bourbon.
The Golden Ratio:
- 2 oz Bourbon
- 1 oz Chilled Espresso
- 1/4 oz Demerara Syrup
- 2 dashes Angostura Bitters
- 1 dash Orange Bitters (optional but recommended)
Combine everything in a mixing glass with a lot of ice. Stir until the vessel is cold. Strain it into your chilled rocks glass over one large cube. Take an orange peel, squeeze it over the glass to release the oils, and rub the peel along the rim of the glass before dropping it in.
If you find the drink too bitter, add a tiny—and I mean tiny—pinch of salt. Salt suppresses bitter receptors on your tongue and actually makes the caramel notes of the bourbon pop. It’s a pro tip used by high-end bartenders to balance out coffee-based drinks.
Stop settling for watery cocktails or over-sweetened lattes. The bourbon espresso old fashioned is the middle ground where bold flavors actually make sense. Get the right ice, find a bourbon you actually like sipping neat, and don't rush the stir.
