The caffeine in a latte comes almost entirely from its espresso, so a standard latte built on a single shot usually carries roughly 63 to 80 mg of caffeine, while one made with a double shot lands closer to 125 to 160 mg. The steamed milk that fills the cup adds none — it only softens and dilutes the coffee, not the buzz. Because most big cafe lattes are pulled as doubles, the drink often has more caffeine than its mellow, milky character suggests. These are averages, though, and the real number swings with the beans, the shot count and the size the cafe pulls.
The short answer: caffeine in a latte
If you want to know how much caffeine is in a latte in one line: it is really just the caffeine in its espresso. A single espresso shot generally holds about 63 to 80 mg of caffeine, so a one-shot latte sits in that same range. A double shot roughly doubles it to about 125 to 160 mg, which is where most standard cafe lattes end up. The frothy layer of steamed milk on top contributes essentially zero caffeine — it changes the texture and the flavor, but not the stimulant load.
Treat those figures as ballpark numbers rather than a precise measurement. Caffeine per shot varies with the coffee itself, so the exact espresso figure is a topic of its own — for the full breakdown of what a shot holds and why it moves around, see our guide to the caffeine in espresso. What matters for a latte is simple: count the shots, and you have your answer.
Why the milk does not change the caffeine
It is a common assumption that a bigger, milkier drink must be "weaker" in caffeine — but caffeine comes from the coffee, not the dairy. Milk, whether whole, skim or a plant-based alternative, has no caffeine to give. Pouring more steamed milk into the cup makes a latte taste smoother and look larger, yet the caffeine stays locked to the espresso underneath.
This is why a latte, a cappuccino and a flat white made with the same number of shots all land at roughly the same caffeine level. A cappuccino simply carries more foam and less liquid milk; a flat white uses less milk and thinner microfoam; a latte drowns the shot in the most steamed milk of the three. Different textures, different volumes — but the caffeine tracks the espresso, so their stimulant content is broadly similar. If you know the shot count, the milk ratio is a distraction.
One shot versus two: the shot count is the whole story
The single biggest lever on a latte's caffeine content is how many shots go into it. Everything else is secondary.
- One shot (~63 to 80 mg): Small cafe lattes and most home-machine lattes are typically built on a single shot. If you pull one shot and steam your milk on top, that is your caffeine.
- Two shots (~125 to 160 mg): Larger cafe sizes usually get a double, because a single shot would be lost in all that milk. Many chains default their medium and large lattes to two shots.
- Three shots (~190 to 240 mg): The biggest sizes at some cafes, or a drink you have asked for "extra," can climb to a triple.
The practical takeaway is that a latte's caffeine is not really about the cup size in ounces or milliliters — it is about how many shots the barista dropped in. A large latte with a single shot has less caffeine than a small latte with a double. If you are watching your intake, the most useful question to ask is simply, "How many shots?"
How a latte compares to other coffee
The easiest way to make sense of latte caffeine content is to line it up against other everyday drinks. Set beside them, a single-shot latte is on the gentler side, while a double-shot latte creeps up toward — and can pass — a regular cup of coffee. Here is a rough comparison. Every figure is an approximation that varies by bean, brew and serving size.
| Drink | Approx caffeine per serving |
|---|---|
| Latte (single shot) | ~63 to 80 mg |
| Latte (double shot) | ~125 to 160 mg |
| Cappuccino or flat white (same shots) | Similar to the matching latte |
| Straight single espresso | ~63 to 80 mg |
| Brewed / filter coffee (8 oz / 240 ml) | ~95 mg |
| Decaf latte | A few mg (often ~2 to 15 mg) |
A single-shot latte sits a little below a standard mug of drip, while a double-shot latte usually edges above it. For the numbers behind a plain cup — and why filter coffee often out-caffeinates a small latte despite tasting milder — see how much caffeine is in a cup of coffee. The espresso figure itself is covered in depth in our dedicated espresso guide, so we keep it as a range here.
What changes the number
Even with the shot count fixed, a few things nudge a latte's caffeine up or down. All of these are reasons to treat any single figure as a hedge rather than a hard fact:
- Single, double or triple shot: By far the largest factor, as above — each extra shot adds roughly another 63 to 80 mg.
- Bean type: Robusta beans carry close to twice the caffeine of arabica, so a blend with robusta pulls a stronger shot than a pure-arabica one.
- How the cafe pulls its shots: Dose, grind, extraction time and shot volume all shift how much caffeine ends up in the cup, which is why two "doubles" from different shops can differ.
- Size defaults: Cafes set their own rules for how many shots each size gets, so a "large" at one place is not the same as a "large" at another.
- Decaf: A decaf shot is not caffeine-free, but it drops the total to just a few milligrams.
Decaf and flavoured lattes
A decaf latte is the low-caffeine option: decaffeination removes most, but not all, of the caffeine, so a decaf latte typically holds only a few milligrams per shot rather than tens. It is not truly zero, which is worth knowing if you are highly sensitive, but it is a fraction of a regular latte.
Flavoured lattes — vanilla, caramel, hazelnut, pumpkin spice and the like — do not change the caffeine math. Those flavors come from syrups, sauces or spices, which add sugar and calories, not caffeine. A caramel latte and a plain latte with the same shots have the same caffeine. The exceptions are lattes built on something other than plain espresso, such as a matcha latte or a chai latte, which draw their caffeine from tea instead of coffee and follow entirely different numbers.
How a latte fits your daily caffeine
To put it in context, health authorities often cite up to about 400 mg of caffeine a day as a reasonable ceiling for most healthy adults. Against that rough guide, a single-shot latte uses a small slice, and a double-shot latte a bigger one — you could have two or three standard lattes and still sit under the commonly cited limit, though everything else you drink counts too. For the fuller picture on daily ceilings, see our guide to how much caffeine per day.
That 400 mg figure is a general benchmark, not a personal prescription. Caffeine sensitivity varies widely, and pregnancy, certain medications, heart conditions, anxiety and sleep issues can all lower the amount that feels comfortable — some people notice a single latte in the afternoon keeps them up at night, while others are unaffected. Responses vary from person to person, and this is general information, not medical advice; if caffeine affects your sleep, health or medication, ask your own healthcare provider about what is right for you.
The bottom line
The caffeine in a latte is the caffeine in its espresso and nothing more: about 63 to 80 mg for a single shot and roughly 125 to 160 mg for the double that most cafe lattes use. The milk, the foam, the size and the syrup all change how a latte tastes and how big it feels, but the shot count is what decides how much caffeine you actually drink. Next time you order, that one question — single or double — tells you nearly everything you need to know.
