This is a party starter, not a sipper, made for lively nights and a crowd that appreciates a bit of theatrical flair with their booze.

Where it came from

The Doctor Pepper shot likely emerged from the raucous energy of bar scenes in the late 20th century. Like many bomb shots, its exact genesis is murky, born more from bartender experimentation and customer daring than a formal creation. It’s a drink designed for speed and impact, popular in places where the vibe is more about celebration than contemplation.

This drink falls squarely into the bomb shot family, a category that includes the Jager Bomb, the Sake Bomb, and the Boiler Maker. What sets the Doctor Pepper apart is its unique flavor profile, replicating the soda’s taste, and the flaming element that adds a dangerous theatricality, making it an experience as much as a drink.

You’ll find the Doctor Pepper thriving in college bars, dive establishments, and any venue where the music is loud and the patrons are looking for a good time. It’s a group order, a round of shots to kick off an evening or keep the energy high. Not a quiet cocktail lounge offering, this one.

What it tastes like

On the palate, the Doctor Pepper delivers a swift, sweet punch of almond liqueur, quickly followed by the intense heat and boozy burn of overproof rum. The flame adds a subtle caramelization to the rum before the entire shot is submerged, diluting into the beer for a soft, malty, and slightly effervescent finish that truly mimics the soda’s distinct flavor.

With 0.25 oz of 151 proof rum and 0.75 oz of almond liqueur, the shot itself is roughly 37% ABV. When dropped into 8 oz of 5% ABV beer (assuming 0.5 of Draft means half a standard mug), the resulting 9 oz drink comes out to about 8.6% ABV. This means a single Doctor Pepper is significantly stronger than a standard beer and packs more pure alcohol than many standard 2 oz cocktails, so pace yourself.

The technique

To build a Doctor Pepper, pour half a mug of cold draft beer. In a separate shot glass, layer the almond liqueur first, then carefully float the overproof rum on top. Ignite the rum’s surface using a long lighter or match. Once flaming, quickly and carefully drop the entire shot glass into the beer. Consume promptly before the flame dies and the glass gets too hot.

The key technique is the swift and deliberate drop of the flaming shot into the beer. Hesitate, and the rum will burn off too much, diminishing the potent kick and the visual effect. A quick drop extinguishes the flame, cools the glass, and mixes the ingredients efficiently, ensuring the signature flavor and impact are delivered as intended.

Ingredient Spotlight

The bottles that make or break this drink.

Overproof Rum

Use: Bacardi 151 (as specified in the recipe), or Wray & Nephew White Overproof for a funkier profile. Any rum 75% ABV or higher will work.
Skip: Standard 40% ABV white rum. It won’t ignite properly and lacks the necessary punch for this drink.
Why: Essential for the dramatic flaming effect and provides a significant alcoholic backbone that cuts through the sweetness and beer.

Almond Liqueur

Use: Disaronno Amaretto, Lazzaroni Amaretto, or other quality almond liqueurs with a balanced sweetness.
Skip: Almond extract or non-alcoholic syrups. You lose the crucial alcohol content and the complex nutty depth that defines the drink.
Why: This ingredient is the primary flavor driver, providing the distinct cherry-almond taste that makes the drink resemble Doctor Pepper soda.

Three Variations

Three real ways bartenders riff on this drink. Same idea, three different jackets.

Funk Bomb

A more aromatic, high-octane kick: Swap the Bacardi 151 for Wray & Nephew White Overproof Rum for a more aromatic and robust Jamaican kick that adds a new dimension to the flame.

Dark Dr. Pepper

Richer, malty base: Use a stout or porter instead of a light lager for a richer, more malty, and less effervescent base that complements the amaretto and rum.

Root Beer Bomb

Similar soda-inspired flavor: Substitute the almond liqueur with a quality root beer schnapps for a different, but similarly nostalgic, soda-inspired flavor profile.

What if I don't have…

Quick substitutions for when the bottle shop is closed.

No OP Rum?

Use a high proof bourbon or rye whiskey. It will still flame, but the flavor profile will shift towards whiskey notes.

No Almond Liqueur?

Try a hazelnut liqueur like Frangelico for a similar nutty sweetness, or a cherry liqueur for a fruitier profile.

No Draft Beer?

Any cold, light-bodied lager or pilsner from a bottle or can will work fine as a substitute.

No shot glass?

A small, heatproof cordial glass or even a sturdy espresso cup can work in a pinch, just ensure it can withstand the heat.

Frequently Asked Questions

Direct answers to what people search for after Googling this drink.

What is in a Doctor Pepper?

A Doctor Pepper typically contains overproof rum, almond liqueur (amaretto), and draft beer. The rum and amaretto are layered in a shot glass, lit on fire, and then dropped into the beer.

Why is it called Doctor Pepper?

The combination of almond liqueur and overproof rum, especially when mixed with beer, creates a flavor profile that remarkably resembles the taste of Doctor Pepper soda.

Is it actually like Doctor Pepper soda?

Yes, many drinkers find the sweet, cherry-almond notes from the amaretto and rum, combined with the beer, to be a surprisingly accurate mimicry of the popular soda.

How strong is a Doctor Pepper shot?

It’s quite potent. The shot itself is around 37% ABV, and when combined with beer, the resulting drink is stronger than a typical beer, delivering a quick alcoholic kick.

Is it dangerous to light on fire?

While the flame is part of the spectacle, always exercise caution. Ensure the rum is properly floated, use a long lighter, and drop the shot quickly to extinguish the flame safely.

Can you make it without fire?

You can, but you lose the dramatic visual effect and a slight caramelization of the rum. It will still taste like a Doctor Pepper, but it won’t be the full experience.

What kind of beer works best?

A light, crisp lager or pilsner is generally preferred as it provides a clean base that doesn’t overpower the distinct almond and rum flavors.

Can I use different rum?

While Bacardi 151 is traditional, any high proof rum (75% ABV or higher) will work for the flame. Just be aware that different rums will impart their own unique flavor notes.
