Bigger cup does not mean bigger caffeine hit. In specialty coffee, a cortado and a latte usually contain the exact same amount, because both are built on the same standard double shot of espresso.
In most specialty cafés, that shared double shot delivers roughly 120 to 160 mg of caffeine in either drink. At big chains, the latte often pulls ahead, simply because larger cups get extra shots while the cortado stays fixed at two.
Milk contributes zero caffeine. Only the espresso decides the answer.
What Each Drink Actually Is
A cortado is espresso cut with a small, nearly equal amount of warm milk. Its name comes from the Spanish word “cortar,” meaning to cut, because the milk softens the espresso’s edge.
Standard specialty recipes keep the cortado tight, at a 1:1 to 1:1.5 ratio of espresso to milk in a 4 oz glass. A latte spreads the same base much thinner, at a 1:3 to 1:5 espresso-to-milk ratio, served in a 10 to 12 oz cup.
Both drinks rest on the same foundation. The Specialty Coffee Association’s espresso parameters call for a dry coffee dose of about 18 to 20 g for a standard double shot.
The Institute for Scientific Information on Coffee puts a typical single espresso shot at 60 to 80 mg of caffeine, and a double measure at 120 to 160 mg.
If you build these at home, the recipe matters more than the gear. Any espresso machine paired with a small steel milk frothing pitcher can produce either drink.
The Caffeine Numbers Side By Side
Use the table below to compare the most common café versions before you order.
| Drink | Typical Size | Espresso Shots | Approx. Caffeine |
| Cortado (specialty standard) | 4 oz | 2 (double shot) | 120-160 mg |
| Latte (specialty standard) | 10-12 oz | 2 (double shot) | 120-160 mg |
| Starbucks Tall latte | 12 oz | 1 | 75 mg |
| Starbucks Grande latte | 16 oz | 2 | 150 mg |
According to Starbucks’ published beverage nutrition information, shot count scales with cup size: one shot in a Tall, two in a Grande, and two in a hot Venti.
At specialty shops, the table above ends in a tie. Both drinks deliver the same double-shot payload.
Milk volume, in other words, changes the experience and never the total. That is also exactly where chains break the tie.
Why Coffee Chains Flip The Answer
At Starbucks, a two-shot cortado-style drink has more caffeine than a Tall latte, matches a Grande exactly, and trails an iced Venti latte. The cup sizes, not the drink names, decide the outcome.
Starbucks does not list a cortado on its core menu, but its espresso-forward drinks use a two-shot doppio base worth about 150 mg. That beats the one-shot, 75 mg Tall latte and ties the 150 mg Grande and hot Venti.
An iced Venti latte pulls three shots, about 225 mg, and overtakes the two-shot cortado. Once again, the shot count did the deciding.
The same shot-count logic carries over to other matchups. Our latte versus iced latte comparison walks through one of them in detail.
European chains like Costa similarly ramp shots upward with drink size, while a cortado keeps a fixed two-shot recipe nearly everywhere. Order a small latte and the cortado wins; order a large and the latte wins.
Caffeine Per Ounce, Where The Cortado Wins Big
Per fluid ounce, a cortado delivers roughly three to four times the caffeine of a latte. The totals stay close while the concentration differs enormously.
The USDA FoodData Central database lists brewed espresso at about 212 mg of caffeine per 100 grams, which works out to roughly 63 mg per fluid ounce of pure espresso. Dilute that espresso with milk and the density drops fast.
A 4 oz cortado holds its caffeine at roughly 30 to 40 mg per ounce of finished drink. A 10 to 12 oz latte lands far lower, around 10 to 16 mg per ounce.
Many drinkers feel a cortado “harder,” and the density explains it. The same caffeine arrives in under half the volume, often in fewer sips.

Beans, Shots, And Home Recipes Shift The Total
The bean itself moves the number. Pure arabica runs about 1.2 to 1.5 percent caffeine by dry weight, while robusta-heavy blends reach 2.2 to 2.7 percent and can push a single shot toward 100 to 140 mg.
Shot style adds small variations too. A ristretto pull, common in cortados, extracts slightly less total caffeine than a standard shot even though it tastes far more intense.
Cafés are not the only place where shot count rules the result. If you pull either drink at home, weigh your dose with a digital coffee scale rather than eyeballing the portafilter basket.
A machine with a built-in grinder and adjustable dosing also makes repeatable shots easier. The Breville Barista Express fits that description for consistent doubles at home.
- Machine type: semi-automatic espresso machine
- Grinder: built-in conical burr grinder
- Dose control: adjustable grind amount
- Milk: steam wand for texturing

The Ordering Rule To Remember
Count the shots and you already have your answer. Equal shots mean equal caffeine, every single time.
Three quick rules cover nearly every café case:
- Equal shots, including the classic two-versus-two specialty build, means a tie at roughly 120 to 160 mg.
- More shots always wins, no matter the drink name or the cup size.
- A latte ordered large is the likelier caffeine winner, because bigger sizes usually carry more shots.
The safest one-line answer: usually the latte, but only if it has more shots. Otherwise they are the same.
Count the shots before you count the ounces. Two shots means roughly 120 to 160 mg in either drink, a dead tie.
Ask your barista how many shots go into the cup, and you will know instantly which drink carries more caffeine.
