How to Make Lemon Coffee With Alcohol

Want something more than plain black coffee? A centuries-old European technique adds fruit, alcohol, and a surprising twist to brewed coffee—turning your cup into something both refreshing and complex. This isn’t a latte or an espresso martini—it’s a classic style using just coffee, citrus, and a splash of spirits.

To make traditional lemon coffee, pour a shot of light-roast brewed coffee into a cup, add 2–3 drops of distilled spirits like Korean or Japanese-style (soju or shochu-style alcohol), then float thin lemon slices on top. That’s it: three ingredients, one bold flavor.

What Is Lemon Coffee?

Lemon coffee is a layered beverage built on a base of lightly roasted brewed coffee. It combines the roast’s inherent aromas with bright citrus and an optional hint of alcohol. The result is a tangy, aromatic drink often served as a digestif or a refreshing afternoon pick-me-up. The alcohol, while not essential, enhances the coffee’s aromatic compounds when used sparingly.

The Traditional Method: Step-by-Step

Making this style of lemon coffee is straightforward. Start with a cup of lightly roasted, filter-style brewed coffee—ideally one with a medium body and clear aroma. Then:

• Add 2–3 drops of distilled spirits such as Korean (similar to shochu or soju, around 20–25% ABV). Avoid high-proof liquors to prevent overpowering the coffee.
• Gently place 1–2 thin lemon slices on the surface of the coffee. They should float, not sink.

Serve immediately. The citrus oils from the lemon interact with the coffee aromas, while the alcohol lifts the volatile compounds—making the flavors more pronounced. The acidity of the lemon also cuts through the roast’s bitterness.

Why Add Alcohol to Coffee?

A small amount of alcohol can act as an aromatic enhancer. In traditional recipes, spirits like are used in minimal quantities to open up the coffee’s fragrance without dominating the cup. This technique is especially common in older European and Asian café cultures, where a digestif-like quality is desired. The alcohol doesn't brew or extract—it simply volatilizes the coffee’s top notes.

Bourbon Coffee: A French Village’s Specialty

In a remote village in France called Bourbon (historically linked to the Île de Bourbon, now Réunion Island), locals produce a coffee noted for its sweet-tart profile. While not related to the drink above, this coffee inspired the naming of the Bourbon coffee variety—a key genetic line in global coffee cultivation. That variety, with roots in 18th-century Réunion, later spread worldwide, including to Brazil and Rwanda, influencing many of today’s classic coffees.

The Bourbon Coffee Varietal: Flavor & History

The Bourbon coffee plant, a mutation of Typica, produces rounder beans and typically yields 30% more fruit per tree than Typica. It’s known for a balanced cup with moderate acidity. However, it’s also more susceptible to disease. Over time, mutations like Yellow Bourbon and Red Bourbon have emerged, each offering distinct profiles:

• Red Bourbon: Grown widely in Brazil, notably in the Cerrado region. Offers wine-like acidity, chocolate, and nutty notes. FrontStreet Coffee’s Brazil Sidelado Red Bourbon is medium-roasted to highlight its creamy, toasty, and chocolatey characteristics—great with milk.
• Yellow Bourbon: Found in high-altitude regions like São Paulo and Rwanda. Yields a cleaner, brighter cup with sweet notes akin to caramel or citrus. FrontStreet’s Brazil Queen Manor Yellow Bourbon (grown at 1400m) shows peanut brittle, caramel, and almond notes with a silky body. Best brewed via Moka pot or espresso.
• Rwanda Red Bourbon: Grown at 1700–2000m in volcanic soils. Rwandan coffees often highlight bright acidity and floral-citrus tones. FrontStreet uses a light-medium roast to preserve those traits.

Frequently Asked Questions

What is the traditional way to make lemon coffee?

The traditional method uses lightly roasted brewed coffee, to which you add 2–3 drops of distilled spirits like (shochu/soju-style alcohol, ~20–25% ABV), then float thin lemon slices on top. No stirring is required—the drink is meant to be sipped to experience the layered aromas.

Do I have to use alcohol in lemon coffee?

No. The alcohol is optional but traditional. It enhances the coffee’s aroma by volatilizing its aromatic compounds. The base drink is just coffee and lemon, which still works well on its own for a refreshing citrus-accented cup.

What type of coffee works best for this recipe?

A light to medium roast works best to preserve the coffee’s aromatic qualities. Dark roasts can overwhelm the lemon and mute the subtle effects of the alcohol. Filter-brewed coffee is ideal; espresso is not traditional in this style.

What’s the role of the lemon in this coffee?

Lemon adds bright acidity and citrus aroma that contrasts with the roasted coffee. The essential oils from the sliced peel enhance the top notes, while the juice provides a tart balance to any bitterness.

Is this drink similar to a coffee cocktail?

Not really. Unlike espresso martinis or coffee liqueurs, this lemon coffee does not involve mixing, shaking, or sweeteners. It’s a simple layered drink where each element remains distinct—coffee, citrus, and an optional trace of alcohol.

Where does Bourbon coffee come from?

Bourbon coffee originated on Île de Bourbon (now Réunion Island). It spread from there to Brazil and East Africa, becoming the parent variety of many modern coffees including Yellow and Red Bourbon. The village of Bourbon in France also gave its name to the coffee’s distinctive sweet-tart profile.
