Where it came from

The Blue Blazer is one of the oldest American showpiece cocktails, attributed to Jerry Thomas in his 1862 Bartender’s Guide. Thomas built it as a flaming pour from one silver mug to another, with the burning whiskey arcing through the air in a long blue ribbon of fire. The drink is the bartending demonstration drink, designed to be watched as much as drunk.

It sits in the hot-toddy family with the Hot Toddy, the Irish Coffee and the Tom and Jerry. All four lean on hot water plus a spirit for the warming-pour character. The Blue Blazer separates itself with the ignite-and-pour technique, which toasts the whiskey vapour in the air and gives the finished drink a smoky-caramel note no other hot cocktail produces.

Best ordered at a heritage cocktail bar with bartenders who know the technique, not at a casual bar where the open flame is a hazard. The drink is theatrical, hot, and meant to be drunk straight from the metal mug while the rim is still warm.

What it tastes like

Sweet caramelised whiskey up front, soft warm water through the middle, smoky-toasted vapour on the finish. The ignite-and-pour technique burns off some of the alcohol while caramelising the sugars in the whiskey, giving the finished drink a softer character than a straight hot toddy. Reads as a warming spirit-and-water pour with a smoky lift.

Around 10 percent ABV in the mug once burned and mixed. Two shots of whiskey at 40 percent ABV plus six shots of water plus a small alcohol burn-off in the flame gives a moderate-strength warming drink. Each metal mug holds about eight ounces of the finished cocktail.

The technique

Heat the whiskey and water in two separate metal mugs over low heat until just steaming, not boiling. Ignite the whiskey with a long match. Pour the burning whiskey into the water mug in a long arc, then pour the mixture back into the original mug. Repeat the back-and-forth pour four to six times, keeping the arc steady. Pour into a heatproof serving glass and drink while warm.

The metal mug is the technique. Glass cracks under direct flame; only solid silver, copper or stainless steel mugs hold up to the heat. Use a long match and keep the arc above any flammable surface. The pour height needs to be at least eight inches for the flame to draw enough air to stay lit; too short and the flame snuffs out mid-pour.

Ingredient Spotlight

The bottles that make or break this drink.

The whiskey

Use: Scotch whisky, bourbon or any 40 percent ABV grain whiskey.
Skip: Cask-strength whiskey above 50 percent ABV. Burns too hot and unsafe.
Why: Whiskey is the spirit base and the flame source. Standard 40 percent ABV ignites cleanly and burns at a controlled rate; cask-strength flares out of control and risks overflow during the pour.

The metal mugs

Use: Solid silver, copper or stainless steel handled mugs.
Skip: Glass, ceramic or thin tin. Cracks or melts under the flame.
Why: Metal mugs hold the heat and the flame without breaking. The handle keeps the bartender’s hand off the hot rim during the back-and-forth pour; without solid metal mugs the technique cannot be performed safely.

Three Variations

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

The standard build

Blue Blazer, classic: Whiskey and water heated separately, ignite the whiskey, pour back and forth between metal mugs four to six times. Serve in a heatproof glass.

The lemon build

Blue Blazer with lemon: Add a strip of lemon peel and a teaspoon of sugar to the water before heating. Same flame technique, brighter citrus finish.

The single-mug build

Quick Blazer: Pour heated whiskey directly over heated sweetened water in a single metal mug, ignite once, stir until the flame dies. Loses the arc, holds the toasted-vapour character.

What if I don't have…

Quick substitutions for when the bottle shop is closed.

No metal mugs?

Skip this drink, do not use glass or ceramic. Try a Hot Toddy instead, which uses the same heat without the flame.

No long match?

A bbq lighter with a long arm works for the ignition. Do not use a short match; the flame is too close to the hand during ignition.

No bourbon or scotch?

Irish whiskey or rye work as substitutes; both ignite and pour the same. Avoid flavoured whiskeys; the additives can flare unpredictably in the flame.

No heatproof glass?

Drink directly from the metal mug once the flame has died and the mug has cooled to handling temperature.

Frequently Asked Questions

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

What is a Blue Blazer cocktail?

Two shots of whiskey and six shots of water, heated separately, the whiskey ignited and poured back and forth between two metal mugs four to six times. A flaming hot cocktail from the 1862 Jerry Thomas Bartender’s Guide.

Why is it called a Blue Blazer?

Named for the long blue ribbon of flame that draws between the two mugs during the back-and-forth pour. The blue colour comes from the alcohol vapour combusting at low oxygen; the blazer name riffs on the fire-arc shape.

Is the Blue Blazer safe to make at home?

Only with solid metal mugs, a long match or lighter, and a clear non-flammable workspace. The pour requires practice; first-timers should rehearse with cold water before adding flame. Keep a damp cloth nearby in case of spill.

How strong is a Blue Blazer?

Around 10 percent ABV in the finished mug. Some alcohol burns off during the flame but most remains; the drink is roughly equal to a standard drink per eight-ounce serving.

What does it taste like?

Sweet caramelised whiskey up front, soft warm water through the middle, smoky-toasted vapour on the finish. The flame caramelises the sugars and adds a smoky note no straight hot toddy produces.

Can I use a different spirit?

Any 40 percent ABV grain spirit ignites and pours the same. Brandy works as a substitute, giving a richer fruit note. Avoid spirits below 35 percent ABV; the flame will not stay lit.

How many times should I pour back and forth?

Four to six times is the standard count. Each pour cools the liquid slightly and adds toasted vapour notes; more than six and the drink loses heat, fewer than four and the smoky character does not develop.

Who invented the Blue Blazer?

Jerry Thomas, the American bartender often called the father of mixology. The recipe appears in his 1862 Bartender’s Guide, the first cocktail recipe book published in the United States.
