A Starbucks Cortado has 230mg of caffeine. That is the number straight off the Starbucks Cortado nutrition page, and it holds for every size because the Cortado only comes one way: an 8 fl oz short cup built on three ristretto shots of Starbucks Blonde Espresso.
So the small cup is the trap. People see 8 ounces and assume it is a light drink. It is not. Three ristretto shots of Blonde is one of the heaviest caffeine loads on the menu, packed into the smallest hot cup Starbucks sells.
Why a tiny drink hits so hard
Two things stack here. First, it is three shots, not one or two. Second, those shots are Blonde. Blonde Espresso runs higher in caffeine than the standard Signature roast, so swapping in three of them is about as concentrated as Starbucks espresso drinks get without going custom.
Ristretto matters less than people think for caffeine. A ristretto pulls a shorter shot with less water, so the flavor is more concentrated, but the caffeine per shot lands in the same range as a normal shot. The 230mg comes from the shot count and the Blonde roast, not from the ristretto pull. If you want the roast breakdown on its own, we covered Starbucks Blonde Espresso caffeine separately.
For context on where 230mg sits: a tall brewed Pike Place is around 235mg, and a standard latte with two shots is far lower. The Cortado is delivering near-drip-coffee caffeine in a third of the volume.
Starbucks Cortado caffeine and nutrition
All figures below are from the Starbucks nutrition pages for the Cortado and the Brown Sugar Oatmilk Cortado. The Cortado is a fixed-size drink, so there is no tall, grande, or venti to compare.
| Drink | Size | Espresso | Caffeine | Calories | Sugar |
|---|---|---|---|---|---|
| Cortado (classic) | 8 fl oz short | 3 ristretto Blonde shots | 230mg | 90 | 6g |
| Brown Sugar Oatmilk Cortado | 8 fl oz short | 3 ristretto Blonde shots | 230mg | 120 | Varies with syrup |
The caffeine does not move between the classic and the flavored versions because the espresso base is identical. Adding brown sugar syrup and oatmilk changes the calories and sugar, not the caffeine.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
Practically, that means one Cortado is already more than half of the FDA reference amount. Two Cortados in a day puts you at 460mg, past the line, before any other coffee, tea, or soda. If you are a two-cup morning person, the Cortado is not a like-for-like swap for a latte.

FAQ
Does the Cortado come in different sizes with more caffeine? No. The Starbucks Cortado is only sold as an 8 fl oz short with three ristretto Blonde shots, so the caffeine is fixed at 230mg. There is no tall or grande Cortado to size up.
Does the Brown Sugar Oatmilk Cortado have less caffeine than the classic? No, both have 230mg. The espresso base is the same three ristretto Blonde shots. The flavored version only adds calories and sugar from the syrup and oatmilk.
Is a Cortado stronger than a latte? On caffeine, yes, by a wide margin. A standard Starbucks latte is built on two shots, while the Cortado uses three Blonde ristretto shots in a much smaller cup, so it delivers more caffeine in less liquid.
