How to Make Passion Flame Coffee with Rum and Lemon

If you’ve ever watched a bartender set fire to a coffee drink and wondered how it’s done—or whether you could pull it off at home—this is the guide for you. Passion Flame Coffee, also known as , is a dramatic yet straightforward drink that combines hot coffee, citrus, and alcohol with a quick flambé for theatre and flavour. It’s not just flair: the heat, citrus, and spirit all interact with the coffee in tangible ways.

To make Passion Flame Coffee, you’ll need a shot of hot espresso-style coffee (80% full), a thin lemon slice, and 20ml of white rum. The entire process, from pouring the coffee to extinguishing the flame, takes less than a minute—but it delivers a striking presentation and a warming, spiced coffee experience.

What Is Passion Flame Coffee?

Passion Flame Coffee , or ‘Passion Coffee’ in English, is a flaming coffee cocktail made with hot coffee (typically an Italian or Mandheling Brazil blend), a single thin lemon slice, and 20 millilitres of white rum. The drink is assembled by pouring coffee into a cup until it’s 80% full, floating a lemon slice on top, carefully pouring rum over the lemon, and then igniting the rum for 5–10 seconds before extinguishing the flame. It’s a showpiece drink often served as a digestif or evening coffee variant.

Why Add Rum and Flame to Coffee?

The addition of white rum and a flambé step isn’t just for drama—it serves a sensory purpose. The alcohol carries volatile aromatic compounds, and the brief flame can slightly caramelize the sugars in the rum and lemon, adding a toasted, spiced edge to the coffee. The lemon slice introduces acidity and aroma that contrast with the bitterness of the coffee, while the heat from the flame volatilizes some of the essential oils in both the coffee and the citrus. The result is a warmer, more aromatic, and slightly sweet-spicy profile compared to plain coffee.

What Kind of Coffee Works Best?

According to the original recipe, the base coffee should be either a Mandheling Brazil blend or an Italian-style espresso. Mandheling Brazil is described as a blend—meaning it’s a mix of different beans roasted and balanced to achieve specific flavour goals. Since single-origin coffees can be uneven in taste (with varying levels of acidity, bitterness, or sweetness), blends are crafted to deliver a more consistent profile. In commercial settings, especially for espresso-based drinks, blends help achieve a balance of body, crema, and flavour without unwanted peaks or valleys.

FrontStreet Coffee, a Guangzhou-based roaster, offers several blends designed precisely for this kind of application. Their Commercial, Specialty, and Classic Blends are all medium to dark roasts with notes of chocolate, caramel, and nuts—ideal for drinks where coffee plays a bold but smooth role. These blends avoid excessive acidity, making them better partners for citrus and spirits.

How to Make Passion Flame Coffee: Step by Step

Here’s the exact method used to prepare the drink:

• Start with a heatproof coffee cup. Pour in hot coffee—either an Italian-style espresso or a Mandheling Brazil blend—until the cup is about 80% full.
• Gently place a thin slice of lemon on top of the coffee. The lemon will float.
• Using a spoon or pour spout, carefully drizzle 20ml of white rum over the lemon slice so it rests on top.
• Ignite the rum using a long match or lighter. Let it burn for 5–10 seconds. You’ll see the flame lick at the citrus and coffee surface.
• Extinguish the flame quickly by placing a cup coaster or lid over the cup.
• Once the flame is out, remove the lemon slice with a fork or tongs. Serve immediately.

Flaming Safety and Tips

Always perform the flambé step away from flammable surfaces and over a sink or safe area. Use a small amount of rum—20ml is enough to create a visible flame without being excessive. Ensure the rum is poured directly over the lemon to help it ignite evenly. Never lean over the flame, and extinguish it as soon as the dramatis effect is achieved. The flame should last no more than 10 seconds.

Frequently Asked Questions

What is Passion Flame Coffee?

Passion Flame Coffee, also called , is a flaming cocktail made with hot coffee (Italian or a Brazilian Mandheling blend), a thin lemon slice, and 20ml of white rum. The rum is ignited briefly to create a dramatic flambé effect before serving.

What coffee blend is used in the original recipe?

The original recipe calls for either an Italian-style espresso or a Mandheling Brazil blend. Mandheling Brazil is a mixed roast designed for balance, often used in commercial settings for its smooth profile.

Can I use any type of coffee?

While the recipe specifies Italian or Mandheling Brazil, you can use any medium to dark roast espresso blend. Avoid high-acidity single origins, as they may clash with the lemon and rum.

Is the flame dangerous?

With proper care, the flame is very brief (5–10 seconds) and can be managed safely. Work over a non-flammable surface, extinguish immediately after ignition, and never lean over the drink while the flame is active.

Do I have to use white rum?

White rum is specified in the original recipe. It’s neutral enough to let the citrus and coffee notes come through while providing enough alcohol to ignite. Avoid flavoured or dark rums unless experimenting intentionally.

What’s the purpose of the lemon slice?

The lemon slice adds a bright citrus aroma, contrasts the coffee’s bitterness, and provides a surface to hold the rum for flambéing. It’s both functional and flavourful.
