Coffee, With a Kick

Coffee cocktails occupy an appealing middle ground: the ritual and bitterness of coffee paired with the pleasure of a well-made drink. Coffee may belong to mornings, and cocktails to evenings, but Boulder bartenders are making a persuasive case for ignoring the distinction.

Mixologists are embracing the pairing of coffee and spirits, creating cocktails that appeal to both the coffee-curious and the devoted cocktail lover. The Espresso Martini may be the most recognizable of the bunch, but it’s worth looking beyond the classic to discover the many creative interpretations bartenders have developed. Part of the attraction is obvious: Coffee brings richness, bitterness, and complexity to a cocktail, while spirits and liqueurs soften those darker flavors with sweetness and warmth. But the current enthusiasm for the pairing goes beyond flavor. In Boulder, coffee cocktails fit comfortably into the increasingly fluid territory between brunch, happy hour, dinner, and late night. 

Coffee also gives bartenders a familiar flavor profile to work with. Its bitter character can temper sweetness, while espresso adds body and aroma. Paired with spirits and liqueurs, coffee can move easily from aperitif territory toward dessert. 

The pairing has found an enthusiastic audience at Jill’s Restaurant & Bistro and T-Zero Lounge inside the St Julien Hotel & Spa. St Julien partners with one of Boulder’s favorite local coffee roasters for its in-house beverage program, including its Ozo Frozen Espresso Martini, made with Ozo Coffee Roasters espresso, Buffalo Trace bourbon cream, Colorado-made Marble Distilling Moonlight Expresso coffee liqueur, Tito’s Handmade Vodka, and Frangelico. The frozen format pushes the drink toward dessert, while espresso keeps the sweetness in check. On St Julien’s patio, with the Flatirons beyond the lawn, it also makes a convincing argument for lingering over an afternoon drink. When the weather turns cold, Jill’s rotates in a Coffee Negroni, offering a darker, more spirit-forward take on the coffee cocktail.

At Corrida, the Carajillo offers a distinct take on the coffee-and-spirits pairing. Perched on the rooftop of what was once the Daily Camera building, the restaurant’s patio offers the sensation of hovering above downtown Boulder. It’s version pairs coffee with Licor 43, the Spanish liqueur known for vanilla and citrus notes. Just a couple of blocks away at Gemini, you can find another Carajillo, where it can accompany an early evening of tapas on Pearl Street. The espresso is dark and earthy, while the cocktail itself is sweet and vanilla-forward, with the coffee providing a bitter counterpoint.

At Rosetta Hall, bartenders take the Espresso Martini in another direction with the Café Olé. Oat milk and cinnamon give the cocktail a creamy, horchata-like character. Pair it with lunch or dinner from one of Rosetta Hall’s eclectic culinary stalls.

The Espresso Martini may be the most familiar expression of the coffee cocktail, but Boulder bartenders are taking considerable liberties with the formula. Bitter Bar offers a more traditional interpretation, while C Bar swaps vodka for tequila and adds Licor 43. At Stella’s Cucina, the drink ventures further from the classic, with an amaro-driven build that brings bitter, herbal notes to the espresso.

Those variations point to what makes coffee such a compelling cocktail ingredient in the first place. Coffee balances sweeter ingredients while bringing enough roasted intensity to stand up to spirits ranging from vodka to tequila and mezcal, and its aroma and texture add dimension to a drink. Whether served frozen, paired with cinnamon and oat milk, or shaken into an inventive take on an Espresso Martini, coffee gives Boulder bartenders plenty to work with—and drinkers plenty of reason to linger over one more round.
