How much caffeine is in a Starbucks coffee?

It depends enormously on what you order: from 75 mg for a tall latte to 410 mg for a venti brewed coffee. On one menu, the spread runs more than fivefold.

And the ranking surprises almost everyone: black coffee climbs highest, far ahead of the espresso drinks.

Drink	Short	Tall	Grande	Venti
Latte, cappuccino	75 mg	75 mg	150 mg	150 mg
Americano	75 mg	150 mg	225 mg	300 mg
Brewed coffee	—	235 mg	310 mg	410 mg

Figures published by Starbucks, checked in August 2026. Recipes can vary by country.

Brewed coffee is the real surprise

A grande brewed coffee delivers 310 mg, and a venti 410 mg — which is more than the 400 mg daily reference, in one cup.

It isn’t an extravagant recipe: it’s arithmetic. Brewed coffee runs around 20 mg per fluid ounce, and a venti is 20 ounces. Volume does all the work.

Against the espresso drinks the gap is striking. A venti latte holds 150 mg; a venti brewed, nearly three times that. The plainest-looking drink on the menu is by far the heaviest.

The large-size trap on milk drinks

Here’s the information that saves money, and it’s counter-intuitive.

On hot milk drinks — latte, cappuccino — the shot count rises once and then stops: one shot in short and tall, two in grande, and still two in venti. Going from grande to venti therefore adds only milk. You pay more, you drink more, you don’t get a milligram of extra caffeine.

On black drinks it’s the reverse: the americano adds a shot at every size, from 75 mg short to 300 mg venti.

The rule to carry to the counter: with milk, size buys volume; without milk, size buys caffeine. It’s the same principle covered in does milk change the caffeine.

A Starbucks shot is 75 mg

Slightly more than a café espresso, which runs 60 to 80 mg. The gap comes mainly from a more generous dose of grounds, not from any particular technique.

It’s the most useful unit of account for reading any chain menu: count the shots, multiply by 75. A grande latte at two shots is 150 mg. A venti americano at four shots, 300 mg. The whole espresso side of the menu follows from that one multiplication.

And if you add an extra shot — offered at most chains — you’re adding exactly 75 mg.

Where it sits across a day

The general reference for a healthy adult is about 400 mg a day and 200 mg in a single sitting.

• A grande latte (150 mg) leaves plenty of room.
• A venti americano (300 mg) passes the 200 mg single-sitting mark.
• A venti brewed coffee (410 mg) passes the whole day’s reference by itself.

None of which is alarming in itself — but it’s the kind of order placed without much thought, while working, that fills the meter in one go. The reference points are detailed in how much caffeine per day.

Reading any chain menu in ten seconds

The method works beyond one brand, because every chain runs on the same principle: standardised espresso shots, counted per drink.

Three questions, in this order:

• Is there milk in it? If so, size is a poor guide: it mostly adds volume, and the shot count caps out quickly.
• How many shots? That’s the only real question. Multiply by 70 to 75 mg and you have your figure, give or take the chain.
• Is it brewed coffee? If so, forget everything above: brewed plays in its own category, and volume alone decides.

That grid works on any menu, including the many that publish no milligram figures at all.

The rest of the menu

Three quick markers:

• Decaf follows the same logic as everywhere: a few milligrams per shot, not zero.
• Iced espresso drinks hold the stated shot count, exactly like their hot equivalents — ice changes nothing.
• Teas and matcha sit considerably lower, in the range of brewed tea.

What to take away

One espresso shot = 75 mg, and the rest of the menu calculates from there. A latte is one or two shots; an americano, one per size.

Brewed coffee is the exception, by a long way: 310 mg grande, 410 mg venti. It’s the least conspicuous drink on the menu and the most loaded. To place all of it against everything else you drink, the full table is in caffeine content by drink.

CaffIQ counts shots rather than sizes — because on a chain menu that’s the only unit that reflects what you actually drank.
