How Much Caffeine Is In A Latte? | Espresso Counts

You order a latte thinking you’re getting a serious caffeine delivery system. In reality, that 12-ounce cup is mostly steamed milk—usually eight to ten ounces of it—with just one or two small shots of espresso running the show. The milk does the heavy lifting for volume, not the caffeine.

The honest answer to how much caffeine is in your latte comes down to one question: how many espresso shots did the barista pull? A single shot contributes about 63 mg of caffeine, while a double shot brings that to roughly 120–160 mg. This article breaks down what drives that number and how a latte stacks up against other coffee drinks.

What Determines a Latte’s Caffeine Content

A latte starts with one or two shots of espresso, followed by steamed milk and a thin cap of foam. The caffeine lives entirely in the espresso — the milk adds volume, texture, and calcium, but zero caffeine.

A single 1-ounce espresso shot contains about 63 mg of caffeine on average. That number can shift based on the bean variety, roast level, and how the barista pulls the shot. A double shot (2 ounces) therefore carries roughly 126 mg, though many cafés pull slightly larger or smaller shots.

Some shops offer a ristretto shot (less water, more concentrated) or a lungo shot (more water, slightly larger volume). These change the flavor and caffeine extraction, but the difference is usually modest — ristretto may extract slightly less caffeine, lungo slightly more, within a range of roughly 50–75 mg per shot.

Why the Milk-to-Coffee Ratio Confuses People

A 12-ounce latte and a 12-ounce mug of black coffee look similar in size, so it’s natural to assume they carry similar caffeine. But they’re built differently — the latte’s volume is mostly milk, while brewed coffee is all coffee. Here’s how the comparison plays out:

• Latte vs. brewed coffee: An 8-ounce mug of brewed coffee contains about 140 mg of caffeine, more than a single-shot latte (63 mg) and comparable to a double-shot latte (126–160 mg).
• Latte vs. cappuccino: Both use the same amount of espresso — usually one or two shots — so caffeine content is nearly identical. The difference is milk texture and foam volume, not caffeine.
• Latte vs. flat white: A flat white also uses double espresso but less milk and a thinner foam layer. Caffeine is the same as a double-shot latte, roughly 120–160 mg.
• Latte vs. americano: An americano is espresso diluted with hot water — no milk. Same espresso shots, same caffeine, just a different mouthfeel.
• Iced latte sizing: A 16-ounce iced latte usually gets the same two shots as a 12-ounce hot version. The extra volume is ice and more milk, not more coffee.

The takeaway: size alone doesn’t tell you much. You have to ask how many espresso shots are inside.

Comparing Latte Caffeine to Other Coffee Drinks

The table below shows how a latte’s caffeine stacks up against common coffee and tea drinks. Mayo Clinic’s latte definition and espresso details confirm that a single 1-ounce shot delivers about 63 mg of caffeine, which means a double-shot latte lands somewhere between brewed coffee and instant coffee in total caffeine.

Drink	Typical Size	Approximate Caffeine
Single-shot latte	8 oz	~63 mg
Double-shot latte	8–12 oz	~126–160 mg
Brewed coffee	8 oz	~140 mg
Instant coffee	8 oz	~100 mg
Black tea	8 oz	~75 mg
Energy drink	8.4 oz	~80 mg

The big surprise for most people: a single-shot latte has less caffeine than an 8-ounce mug of black tea. If you’re looking for a gentler morning jolt, a single-shot latte is one of the milder coffee-based options.

Factors That Affect Your Latte’s Caffeine Hit

Even within the same café, the same drink order can vary in caffeine from day to day. These five factors play the biggest role:

1. Number of espresso shots: This is the single biggest variable. A single shot gives you ~63 mg; a double shot gives ~126–160 mg. Some cafés default to double shots for all hot lattes, others use singles for smaller sizes.
2. Bean origin and roast level: Lighter roasts retain slightly more caffeine by weight than darker roasts, though the difference is small — maybe 5–10 mg per shot. Bean variety (Arabica vs. Robusta) matters more: Robusta beans contain roughly twice the caffeine of Arabica.
3. Extraction method and pull time: A shorter pull (ristretto) uses less water and may extract slightly less caffeine. A longer pull (lungo) extracts more. Standard espresso pulls aim for about 25–30 seconds, but barista technique varies.
4. Brand and café differences: Starbucks reports that a 16-ounce grande latte made with two espresso shots contains 150 mg of caffeine. La Colombe’s 9-ounce Double Draft Latte (oatmilk) lists 120 mg per can. Brand sourcing and shot recipes shift the final number.
5. Size of the drink: Many coffee shops use the same two espresso shots for a 12-ounce, 16-ounce, or even 20-ounce latte — only the milk volume changes. Ordering a larger size does not mean more caffeine unless you ask for an extra shot.

How Latte Caffeine Stacks Up Against Common Alternatives

People often wonder whether a latte or a standard mug of brewed coffee delivers more caffeine. Cleveland Clinic’s comparison of 140 mg caffeine per 8-ounce cup shows that a double-shot latte lands in roughly the same range, while a single-shot latte has about half the caffeine. For anyone tracking intake, the distinction matters — especially during pregnancy, where the recommended limit is 200 mg per day, roughly equal to one double-shot latte.

Latte Size and Shots	Approximate Caffeine
Single-shot (8 oz)	~63 mg
Double-shot (8–12 oz)	~126–160 mg
Starbucks grande (16 oz, 2 shots)	~150 mg
Triple-shot (12–16 oz)	~189–240 mg

A latte with three shots pushes past most standard caffeine limits in a single drink. Most cafés will happily add an extra shot if you ask, but it’s worth knowing where your latte lands before you order that third pour.

The Bottom Line

A latte’s caffeine comes down to one number: the espresso shot count. Single-shot lattes deliver about 63 mg, double-shot lattes roughly 120–160 mg, which is comparable to an 8-ounce mug of brewed coffee. Ignore the cup size — more milk doesn’t mean more caffeine. Ask your barista how many shots are in your size, and add an extra if you want the boost.

If you’re counting caffeine for pregnancy, heartburn sensitivity, or a general health check, your barista or the café’s nutrition page can confirm the shot count — and your doctor can help you set a daily target that fits your specific situation.
