How much caffeine is in Latte (large, 2 shots)?

A large 350 ml (11.8 fl oz) latte made with two espresso shots contains 126 milligrams of caffeine. This single serving provides the caffeine equivalent of approximately 1.3 standard cups of drip coffee—based on a 240 ml cup containing 96 mg of caffeine—and represents 32% of the 400 mg daily maximum recommended by the U.S. Food and Drug Administration. With a caffeine concentration of 36 mg per 100 ml, the dose is moderate compared to brewed coffee but substantially higher than a small latte made with a single shot (68 mg).

After ingestion, the caffeine typically reaches peak plasma levels within 45 to 60 minutes, producing increased alertness and focus. The milk content can slightly smooth the onset of effects compared to a straight espresso, but the total caffeine load remains unchanged. Because the serving volume is 350 ml, the drink also contributes to daily fluid intake, although caffeine’s mild diuretic action is mostly offset by its water content.

For most healthy adults without caffeine sensitivity, this amount rarely causes jitters or sleep disturbances when consumed in the morning or early afternoon. However, individual tolerance varies, and those with certain health conditions or altered caffeine metabolism may wish to monitor their response. The 126 mg figure is a representative estimate for a two-shot latte; actual values can shift based on bean variety, extraction technique, and shot volume, as detailed below.

How long Latte (large, 2 shots) stays in your system

Caffeine follows first-order elimination kinetics with a population-average half-life of 5.7 hours. Starting from a 126 mg dose, the amount remaining in the body can be calculated with the formula remaining = dose × 0.5^{(hours / 5.7)}. After 3 hours, approximately 87 mg remains (126 × 0.5^(3/5.7) = 87 mg). At 6 hours, the level drops to about 61 mg; at 9 hours, to 42 mg; and after 12 hours, roughly 29 mg still circulates—about 23% of the original dose—continuing to exert pharmacological effects. These figures align with the standard decay model and show that even half a day later a measurable quantity of caffeine persists.

To illustrate, consider drinking this large latte at 3:00 p.m. By 9:00 p.m., six hours later, approximately 61 mg remains—equivalent to a single espresso shot. At midnight, nine hours later, still about 42 mg lingers, more than half a cup of green tea (28 mg). According to Drake et al. (2013), even 400 mg of caffeine taken six hours before bed reduced total sleep by over an hour, and smaller residual doses can impair deep sleep in sensitive individuals.

Daily Limit and Sleep Timing

The 400 mg daily limit set by the FDA and EFSA means a healthy adult could consume up to three large lattes (378 mg total) and still remain within the recommendation. A fourth would push the total to 504 mg, exceeding the guidance. This assumes no other caffeine sources; adding tea, chocolate, or soft drinks would narrow the margin further. For context, one large latte uses 32% of the daily quota.

For sleep quality, the timing of your last dose is critical. With a 5.7-hour half-life, a 126 mg latte consumed at 3:00 p.m. leaves 61 mg at 9:00 p.m. and 42 mg at midnight. To minimize sleep disruption, many experts recommend stopping caffeine at least 8 hours before bedtime. For an 11:00 p.m. bedtime, that implies a cutoff around 3:00 p.m. Our latest cup before bedtime tool can refine this window. Pregnant women should limit total caffeine to 200 mg per day, per the EFSA; this single latte already accounts for 63% of that limit. Adolescents are generally advised to keep daily intake under 100 mg, so this drink alone exceeds their cap. Anyone with anxiety disorders or genetically slow caffeine metabolism should adopt more conservative limits.

How It Compares to Other Drinks

Among espresso-based beverages, the large two-shot latte at 126 mg falls in the upper tier. It has the same caffeine as a double espresso (126 mg) and an Americano (126 mg, with two shots), since all three are built on two espresso shots. The flat white (130 mg) is nearly identical, typically using two shots as well. In contrast, a small latte (68 mg) and a cappuccino (63 mg) contain roughly half the caffeine because they are most often made with a single shot. The cortado (79 mg) and macchiato (63 mg) are even lower, while a mocha (95 mg) adds one shot plus chocolate, which contributes negligible caffeine.

Compared to non-espresso benchmarks, the large latte’s 126 mg is 1.3 times a standard 240 ml drip coffee (96 mg). It surpasses a 250 ml can of Red Bull (80 mg) but falls short of a 473 ml Monster Energy (160 mg). A 355 ml Coca-Cola Zero (34 mg) has less than one-third the caffeine.

What changes the number for Latte (large, 2 shots)

Factors That Change Caffeine Content

The caffeine in a latte depends almost entirely on the number and type of espresso shots. A large latte in most cafés contains two shots, yielding 126 mg. A smaller 240 ml latte typically holds one shot, providing only 68 mg. Conversely, an extra-large latte often includes three shots, raising caffeine to around 189 mg. Milk volume does not affect caffeine; the shot count is the key variable.

Even with a fixed shot count, actual caffeine per shot varies. According to USDA FoodData Central and the Mayo Clinic, a single espresso shot ranges from 60 to 80 mg, influenced by:

• Bean origin and species: Robusta beans contain roughly twice the caffeine of Arabica.
• Roast level: Darker roasts can yield slightly less caffeine by volume, though weight-based differences are minimal.
• Grind fineness and water contact time: Finer grinds and longer extraction increase caffeine yield.
• Machine pressure and barista technique: Tamping pressure and shot duration alter extraction efficiency.

Decaf versions are not caffeine-free. FDA labeling permits decaffeinated coffee to retain up to 3–15 mg of caffeine per shot. A large decaf latte with two shots therefore delivers roughly 6–30 mg—comparable to a small cup of green tea (28 mg) at the upper end. This amount can still affect individuals highly sensitive to caffeine or those under medical restrictions. Always confirm shot count with the barista, as the term “large” may be interpreted differently across coffee shops.

Where this figure comes from

Where the Number Comes From

The 126 mg value is based on the average caffeine content of a standard espresso shot as reported by USDA FoodData Central and the Mayo Clinic—commonly 63 mg per 30–60 ml shot. Two shots thus yield 126 mg. Our open caffeine dataset aggregates such lab-analyzed values and is regularly reviewed against current research. Published values can differ because extraction yield varies with bean origin, roast, grind, machine type, and barista technique; a two-shot latte can realistically range from 100 to 150 mg. We select a defensible midpoint that aligns with the most authoritative sources.

If updated USDA or EFSA data revise the average espresso shot caffeine content, we will adjust this figure accordingly. Brand-specific values (e.g., Starbucks, Dunkin’) may differ slightly from the generic estimate and can be found in their respective nutritional guides. We link directly to the FDA and EFSA safety recommendations to provide context, as they represent the gold standard for public health guidance on caffeine intake.

Bottom line

A large 350 ml latte with two espresso shots delivers 126 mg of caffeine, which is equivalent to roughly 1.3 cups of drip coffee and represents 32% of the FDA’s 400 mg daily limit. This dose matches that of a double espresso or an Americano and places the large latte in the higher caffeine tier among espresso-based drinks.

After consumption, the caffeine follows a half-life of about 5.7 hours: half the original dose remains after nearly 6 hours, and a quarter persists after 12 hours. If you drink one at 3:00 p.m., about 61 mg will still be active at 9:00 p.m. and 42 mg at midnight—amounts that can affect sleep for sensitive individuals. Pregnant women, adolescents, and those with low tolerance should account for this dose when planning their daily caffeine cap.
