If you have ever wondered how much caffeine in a carajillo ends up in your glass, the short version is that it comes from the espresso, not the alcohol. A carajillo is a shot of espresso combined with a spirit or liqueur, so a single-shot pour carries roughly 63 mg of caffeine, while a double-shot build lands closer to 125 mg. Those numbers are rough averages that shift with the beans, the roast, and how the shot is pulled, so read them as ballpark figures.
Below we break down where that caffeine actually comes from, why the single-versus-double choice is the biggest variable, and how a carajillo stacks up against a plain espresso. For the full story on what a carajillo is and how it is built, see our carajillo recipe guide.
How much caffeine in a carajillo? The short answer
A carajillo's caffeine content is essentially the caffeine of its espresso base. The spirit - classically Licor 43, brandy, or rum - brings flavor, sweetness, and warmth, but it contributes no caffeine of its own. So if you know how many espresso shots went into the glass, you already have a solid estimate of the total.
As a hedged rule of thumb, a typical single espresso shot holds around 63 mg of caffeine, and a double holds roughly 125 mg. Real-world results vary widely - anywhere from about 50 mg to 80 mg per single shot is common depending on the coffee - so treat any single figure as an approximation rather than a precise reading. The point is that the coffee, not the cocktail element, is doing all the caffeine work.
One practical wrinkle: because a carajillo is also an alcoholic drink, it can be easy to lose track of how many shots you have had over an evening. If you like to know your caffeine intake, it helps to think of the drink as espresso first and cocktail second, and to count shots the same way you would count plain espressos.
Where the caffeine in a carajillo comes from
Every bit of caffeine in a carajillo arrives with the espresso. When hot water is forced through finely ground, tamped coffee under pressure, it extracts caffeine along with the oils and dissolved solids that give espresso its body and crema. That concentrated shot is the entire caffeine story here. For a closer look at the numbers behind a shot, see our guide to caffeine in espresso.
The alcohol side of the drink adds nothing to the caffeine total. Spirits and liqueurs such as brandy, rum, or a vanilla-forward liqueur are caffeine-free, so pouring more of them changes the drink as a cocktail but leaves the caffeine untouched. A boozier carajillo is not a more caffeinated one - the two are simply separate ingredients doing separate jobs.
This is also why bean choice and roast matter. A robusta-heavy blend generally carries more caffeine than a pure arabica, and the grind, dose, and extraction time all nudge the final figure up or down. Two carajillos made with the same method but different coffee can genuinely differ in their caffeine, which is part of why any published mg number is an estimate.
It is worth noting that total volume does not dilute the caffeine. A carajillo served long over a tall glass of ice holds the same caffeine as the same shot served short, because adding ice, spirit, or a splash of water spreads the drink out without removing any caffeine. The mg count is set the moment the espresso is pulled; everything after that is about taste, temperature, and dilution of flavor rather than caffeine.
Single vs double shot: the main lever
The single most important factor in a carajillo's caffeine is simple: how many shots of espresso are in it. Many bars build the drink on one shot, but plenty of versions - especially larger or iced servings - start from a double. That one decision can roughly double the caffeine, from around 63 mg to about 125 mg.
So does a carajillo have caffeine worth thinking about? Yes, but the amount is largely in your control. A single-shot carajillo sits in the same range as a small espresso drink, while a double-shot version is closer to a standard mug of drip coffee in caffeine terms. If you are keeping an eye on your intake, the easiest move is to ask whether the drink is built on one shot or two before you order.
A few things that do not change the caffeine, despite feeling like they might: the amount of spirit, whether the drink is shaken or stirred, whether it is served hot or over ice, and how much foam sits on top. None of those touch the coffee, so none of them touch the caffeine. The espresso count is the whole ballgame.
How a carajillo compares to a plain espresso
In caffeine terms, a carajillo and a plain espresso are close to identical for the same number of shots. The carajillo just arrives with a spirit stirred or poured in. A single-shot carajillo and a single espresso both hover around 63 mg; a double-shot carajillo matches a double espresso near 125 mg. If you want the fundamentals of the shot itself, our explainer on what an espresso shot is covers the basics.
The practical difference is not the caffeine - it is the alcohol and the serving style. A carajillo is often sipped as an after-dinner drink in places like Spain and Mexico, sometimes shaken cold over ice, whereas a straight espresso is usually a quick standalone hit at the bar. The caffeine math, though, stays tied to the espresso either way, which makes a carajillo easy to plan around if you already know your espresso habits.
Carajillo caffeine content at a glance
Here is a rough, hedged guide to carajillo caffeine mg by build. Actual figures depend on the shot size, the bean, and the roast, so read these as estimates rather than fixed values.
| Carajillo version | Espresso base | Rough caffeine |
|---|---|---|
| Single-shot carajillo | 1 espresso shot | ~63 mg (roughly 50-80 mg) |
| Double-shot carajillo | 2 espresso shots | ~125 mg (roughly 100-160 mg) |
| Decaf-based carajillo | 1 decaf shot | ~3-15 mg (trace only) |
The takeaway: the spirit never changes the caffeine, so the number of shots - and whether the coffee is caffeinated or decaf - is what actually moves the needle. If you enjoy the ritual but want to keep caffeine low, a decaf-based carajillo keeps the flavor and the spirit while dropping the coffee stimulant down to a trace, since even decaf shots carry a small residual amount rather than zero.
A note on moderation
For most healthy adults, a commonly cited general guide is up to about 400 mg of caffeine a day, which would cover several single-shot carajillos or a couple of double-shot ones - though that is a broad average, not a personal target. Our overview of how much caffeine per day puts that figure in context and explains why individual comfort levels differ.
The alcohol in a carajillo is a separate matter with its own sensible moderation, entirely unrelated to the caffeine. If you are sensitive to caffeine, are pregnant or breastfeeding, take medication, or are avoiding alcohol for any reason, it is worth asking your own healthcare provider what makes sense for you. Responses vary from person to person, and this is general information, not medical advice.
