Espresso is stronger than cappuccino by concentration, not by caffeine. A standard cappuccino is a single shot of espresso with steamed milk poured over it, so the caffeine in the cup is the caffeine in the shot: the same amount, spread through five to six times as much liquid.
Does Espresso Have More Caffeine Than Cappuccino?
Not per serving. Both drinks are built on the same single shot, so both carry roughly the same caffeine.
A shot of espresso contains about 63 mg of caffeine, based on the USDA’s figure of 212 mg per 100 g. Starbucks lists 75 mg for a Tall cappuccino, which is also a single shot. The gap between the two numbers comes down to bean, dose and roast rather than to the drink itself.
Where the answer changes is size. Starbucks pours one shot in a Short and a Tall, and two in a Grande and a Venti, so a large cappuccino carries more total caffeine than a single espresso does. Our guide to how many shots are in a cappuccino breaks that down by size.
What Is The Difference Between A Cappuccino And Espresso?
| Espresso | Cappuccino | |
|---|---|---|
| Volume | 25-30 ml | 150-180 ml |
| Espresso shots | 1 | 1 (2 in larger sizes) |
| Caffeine per serving | ~63-75 mg | ~63-75 mg |
| Caffeine per 100 ml | ~210 mg | ~40 mg |
| What is in it | Espresso only | Espresso, steamed milk, foam |
The Istituto Espresso Italiano specifies a certified cappuccino as 25 ml of espresso with 100 ml of milk, steam-foamed until it grows to about 125 ml. Craig Dickson of Veneziano Coffee, a World Barista Championship judge, describes a competition cappuccino as “30 millilitres of espresso blended with milk in a 150-millilitre to 180-millilitre cup”, with at least one centimetre of microfoam.
Both specifications describe the same relationship: the espresso is identical in each drink, and the cappuccino adds milk to it. Milk is the bulk of a cappuccino, roughly four parts milk to one part espresso, which is covered in more detail in our breakdown of how many ml are in a cappuccino.
The same logic holds against a latte, which takes the same espresso and adds still more milk. See the difference between a latte and a cappuccino for that comparison.
Which Tastes Stronger, Espresso Or Cappuccino?
Espresso, and by a wide margin. The reason is the same dilution: nothing in the cup softens it. There is no milk to round out the bitterness and no foam to lighten the texture, so you taste the coffee at full concentration.
A cappuccino delivers that same coffee across a larger, milkier drink, which is why it reads as smoother rather than weaker. If you find espresso harsh, what you are tasting is concentration, not extra caffeine.
So Which Should You Order?
If you want the caffeine without the volume, order the espresso: the same hit in 30 ml, finished in one go. If you would rather the same coffee lasted, a cappuccino gives you identical caffeine in a longer, softer drink.
Neither is the stronger coffee in the way that affects how awake you end up. That only changes when a second shot goes in, which is worth knowing if you are wondering whether a cappuccino will keep you awake.
