How Much Caffeine Is in a Cappuccino? Count the Shots
A cappuccino has exactly as much caffeine as the espresso inside it. USDA data puts a single 1 fl oz shot at about 63 mg, making a double roughly 126 mg. Starbucks lists 75 mg per shot, so its Short and Tall cappuccinos land at 75 mg while the Grande and Venti hit 150 mg. Milk and foam contribute zero caffeine; only the shot count matters.
Caffeine in a Cappuccino by Shot Count
Multiply espresso shots by caffeine per shot. Two reference points: the USDA average for restaurant espresso, and Starbucks' published figure for its Signature Espresso Roast.
| Shots | USDA espresso (63 mg per 1 fl oz shot) | Starbucks Signature espresso (75 mg per shot) |
|---|---|---|
| 1 (single) | about 63 mg | 75 mg |
| 2 (double) | about 126 mg | 150 mg |
| 3 (triple) | about 189 mg | 225 mg |
Formula: shots x mg per shot. Milk and foam add no caffeine.
The USDA figure comes from FoodData Central entry 171891: 212 mg per 100 g of espresso, or about 62.8 mg per 1 fl oz shot. Starbucks publishes 75 mg for a solo and 150 mg for a doppio.
Starbucks Cappuccino Caffeine by Size
| Starbucks cappuccino | Cup | Espresso shots | Caffeine |
|---|---|---|---|
| Short | 8 fl oz | 1 | 75 mg |
| Tall | 12 fl oz | 1 | 75 mg |
| Grande | 16 fl oz | 2 | 150 mg |
| Venti (hot) | 20 fl oz | 2 | 150 mg |

A Tall and a Short both carry one shot (75 mg). A Venti and a Grande both carry two (150 mg). The extra ounces in the larger cup are steamed milk and foam.
A Blonde espresso swap changes the math. Starbucks does not list a Blonde cappuccino, but it lists its Blonde Vanilla Latte at 85 mg for one shot and 170 mg for two. The default cappuccino uses Signature Espresso Roast, so the table above applies unless you request the swap.
Cappuccino vs Latte, Flat White and Coffee at the Same Size
At Starbucks, a cappuccino and a caffè latte have identical caffeine at every size because they use the same number of shots. The flat white runs higher because it gets an extra shot, and brewed Pike Place roughly doubles the espresso-based drinks.
| Drink (hot) | Short 8 oz | Tall 12 oz | Grande 16 oz | Venti 20 oz |
|---|---|---|---|---|
| Cappuccino | 75 mg | 75 mg | 150 mg | 150 mg |
| Caffè Latte | 75 mg | 75 mg | 150 mg | 150 mg |
| Flat White | 130 mg | 130 mg | 195 mg | 195 mg |
| Caffè Americano | 75 mg | 150 mg | 225 mg | 300 mg |
| Pike Place Roast (brewed) | 155 mg | 235 mg | 315 mg | 390 mg |

The taste gap between a cappuccino and a latte is milk ratio, not caffeine. More foam, less liquid milk, stronger espresso flavor per sip. Starbucks lists the flat white at 130 mg even in the 8 oz Short.
Does a Cappuccino Have More Caffeine Than Coffee?
Usually no. A 16 oz Starbucks cappuccino has 150 mg; a 16 oz Pike Place has 315 mg. Brewed coffee is a full cup of extracted coffee; a cappuccino is one or two small shots topped up with milk.
The FDA puts a 12 fl oz cup of regular brewed coffee at 113 to 247 mg. A double-shot cappuccino at the USDA average is about 126 mg, near the low end of that range. Per ounce, espresso is denser (about 63 mg/fl oz vs roughly 9 to 21 mg/fl oz for drip coffee). Per cup, drip wins because you drink more of it.
Why Is a Bigger Cappuccino Not Stronger?
Because the shot count stays flat until the cup size forces a second shot. A Tall is 50% more liquid than a Short but zero milligrams more caffeine.
| Starbucks cappuccino | Caffeine per fl oz |
|---|---|
| Short (75 mg / 8 fl oz) | 9.4 mg |
| Tall (75 mg / 12 fl oz) | 6.3 mg |
| Grande (150 mg / 16 fl oz) | 9.4 mg |
| Venti (150 mg / 20 fl oz) | 7.5 mg |
The Short and the Grande tie as the most concentrated cappuccinos Starbucks sells, at 9.4 mg per fl oz. If you want the strongest flavor per sip and only need one shot's worth of caffeine, order the smallest cup.
What About Dunkin and McDonald's?
Neither chain publishes caffeine for its cappuccino in US nutrition materials. Dunkin's Nutrition Guide lists calories and macros for Small, Medium and Large cappuccinos but no caffeine column. McDonald's US product pages show calories only.
Third-party estimates exist, but they are not sourced from Dunkin or McDonald's. For Dunkin's other drinks, with each figure marked as published or estimated, see Dunkin caffeine content.
How Many Cappuccinos Reach 400 mg?
The FDA cites 400 mg a day for most healthy adults. Using Starbucks' numbers:
- Single-shot cappuccinos (75 mg): 400 / 75 = 5.3.
- Double-shot cappuccinos (150 mg): 400 / 150 = 2.7.
That 400 mg covers caffeine from every source: coffee, tea, supplements, all of it. It is a ceiling, not a target. Pregnant or breastfeeding? Talk to your health care provider about caffeine.

Frequently Asked Questions
Why does a cappuccino taste stronger than a latte if the caffeine is the same?
It comes down to foam. A cappuccino has a thicker layer of microfoam and less liquid milk, so each sip carries a higher ratio of espresso flavor to dairy. A latte pours more steamed milk into the cup, softening the taste. The shot count and caffeine are identical at every Starbucks size; only the texture and perceived boldness change.
How much caffeine is in a decaf cappuccino?
Starbucks does not list a caffeine figure on its cappuccino page for the decaf version. If you order decaf, the barista swaps to decaf espresso. Check the Starbucks app for the most current decaf espresso number, or ask at the counter.
Does Starbucks have an iced cappuccino?
Not on the current US menu as of Oct 2026. The closest iced espresso-and-milk option is the Iced Caffè Latte. For its sizes and caffeine, see Starbucks caffeine content.
Can you add an extra shot to a cappuccino?
Yes. Each additional Signature Espresso shot adds 75 mg. A Grande cappuccino with an extra shot becomes a triple at 225 mg.
Between the Morning Cappuccino and Dinner
A single-shot cappuccino delivers 63 to 75 mg of caffeine, about the same as one Roon pouch at 80 mg. The difference is what happens next. Coffee's caffeine clears at its normal rate; you feel the fade by early afternoon and either brew another cup or push through.
Roon pairs its 80 mg of caffeine with 60 mg L-theanine, 25 mg methylliberine (Dynamine), and 5 mg theacrine (TeaCrine). Methylliberine slows caffeine's clearance: a randomized, double-blind crossover PK study (n=12) found that co-administration cut caffeine's oral clearance from 41.9 to 17.1 L/hr and extended its half-life from 7.2 to 15 hours, with no increase in peak concentration. That study used 100 mg methylliberine and 150 mg caffeine, about 4x the methylliberine and 1.9x the caffeine in a single Roon pouch, so the mechanism applies directionally, not at the study's exact magnitude. A longer blood half-life is not the same as feeling it that long: expect roughly six to eight hours of steady lift from one pouch. Place it under the lip anywhere, no barista required, and give yourself at least eight hours before you plan to sleep.
Zero nicotine, zero sugar (contains sucralose), from $9.16 per tin of 15 pouches. Stay within 4 pouches a day and 400 mg of caffeine from all sources, cappuccinos included. Try Roon.
