How much caffeine is in McDonald's McCafé Latte (Medium)?

A medium McDonald's McCafé Latte contains 110 mg of caffeine. This 350 ml (11.8 fl oz) serving delivers a caffeine concentration of approximately 31.4 mg per 100 ml, which is lower than a typical brewed coffee but comparable to other espresso-based milk drinks. The caffeine content is equivalent to roughly 1.1 cups of standard drip coffee (using a 240 ml cup containing 96 mg of caffeine as the reference). For most healthy adults, this represents 28% of the 400 mg daily limit suggested by the FDA.

A latte is made by combining one or more shots of espresso with steamed milk and a small layer of foam. Because espresso forms the base, the caffeine delivery follows a similar pattern: onset within 15–30 minutes after consumption, peak alertness around 60 minutes, and a gradual decline over several hours. The milk in a latte does not alter the total caffeine but can moderate the perception of the stimulant’s effects by slowing gastric emptying slightly, making the rise in alertness feel smoother compared to a straight espresso shot.

This drink sits in a moderate zone — it provides enough caffeine to sharpen focus without approaching the rapid spike of a strong drip coffee or energy drink. The 110 mg figure is a population average derived from McDonald’s standard recipe and testing; individual servings may vary slightly due to natural variations in coffee beans and preparation factors. As with any caffeinated beverage, the actual experience depends on personal tolerance, metabolism, and whether it is consumed with food.

How long McDonald's McCafé Latte (Medium) stays in your system

Caffeine follows first-order elimination kinetics, with a population average half-life of 5.7 hours. This means that after drinking a medium McCafé Latte, the amount of caffeine remaining in the body decreases predictably. Starting from 110 mg, the decay model remaining = dose × 0.5^(hours / 5.7) yields: after 3 hours, approximately 76 mg; after 6 hours, about 53 mg; after 9 hours, around 37 mg; and after 12 hours, roughly 26 mg. These values are estimates based on an average half-life; individual rates can range from 2.7 to 9.9 hours depending on factors like genetics, liver function, and pregnancy status. For personalized projections, the caffeine half-life calculator shows how the remaining caffeine level evolves minute by minute for this specific drink size.

To put these numbers in context: if you drank this latte at 15:00, by 21:00 you would still have about 37 mg of caffeine in your system — slightly more than a 355 ml can of Coca-Cola Coke Zero (34 mg). By bedtime at 23:00, the remaining 26 mg is equivalent to less than a third of a single espresso shot and may still interfere with deep sleep in sensitive individuals. For those who want to minimize sleep disruption, the latest cup before bedtime calculator can personalize the cutoff time based on your target bedtime and the drink’s caffeine dose.

With 110 mg of caffeine, a single medium McCafé Latte uses about 28% of the FDA and EFSA recommended maximum daily intake of 400 mg for healthy adults. This means that consuming up to three such lattes in a day (330 mg total) would still leave a buffer before hitting the limit, though individual sensitivity varies widely. For pregnant individuals, the same health authorities recommend a limit of 200 mg per day, making one latte already 55% of the allowance; a second would exceed the guidance. Adolescents are often advised by health organizations to limit caffeine to 100 mg per day, so this single drink exceeds that conservative threshold, cautioning against regular consumption in younger age groups.

Considering sleep hygiene, the timing of consumption is critical. Research published in the Journal of Clinical Sleep Medicine (Drake et al., 2013) demonstrated that 400 mg of caffeine consumed even six hours before bedtime can reduce total sleep by over an hour. With a 110 mg dose, the effect is less dramatic but still measurable. Using the half-life decay, if one aims for less than 50 mg of caffeine in the system at bedtime (roughly the amount in a strong cup of tea), and assuming a bedtime of 23:00, the latte should be consumed by approximately 16:30. To have nearly complete elimination (below 10 mg) at bedtime, it would need to be finished by 12:00 noon. Caffeine blocks adenosine receptors, which build up sleep pressure throughout the day; even low residual levels can disrupt deep sleep architecture.

Individual differences in caffeine metabolism mean these guidelines are starting points. Factors such as oral contraceptive use, pregnancy, liver disease, and certain medications can extend caffeine’s half-life by up to 2–3 times. People who experience jitteriness, anxiety, or heart palpitations even with moderate doses may need to set a lower personal limit. The safe daily limit by body weight calculator translates the general 400 mg recommendation into a more personalized figure based on body mass, which can be a helpful benchmark for those unsure of their tolerance.

Among major coffee chain drinks in our dataset, the McDonald's McCafé Latte (Medium) at 110 mg falls on the lower half of the caffeine spectrum. When normalized for volume, it contains about 0.31 mg/ml, which is nearly identical to the Starbucks Caffè Latte (Grande), which delivers 150 mg in 473 ml (0.32 mg/ml). Both are espresso-and-milk drinks, so their similar caffeine density suggests a comparable number of espresso shots relative to total volume. In contrast, a Starbucks Pike Place Brewed (Grande) packs 310 mg in the same volume — nearly three times the caffeine per milliliter due to its different brewing method (filtered drip vs. espresso). This underscores how the preparation method and coffee-to-water ratio dramatically influence caffeine content, even at identical serving sizes.

Looking more broadly, the McCafé Latte sits below the Dunkin' Original Blend (Medium) at 210 mg (414 ml) and the Starbucks Cold Brew (Grande) at 205 mg. It is comparable to Starbucks' flavored espresso drinks like the Caramel Macchiato (150 mg) and Cappuccino (150 mg), though those are served in larger volumes. Against reference drinks outside coffee shops, 110 mg is 38% more caffeine than a 250 ml Red Bull (80 mg), 31% less than a 473 ml Monster Energy (160 mg), and nearly four times the caffeine of a 240 ml cup of green tea (28 mg). This positions the medium latte as a moderate-strength choice — not as potent as a Cold Brew or Pike Place, but more substantial than a single espresso shot (63 mg) or a standard tea. To directly compare multiple drinks side-by-side, the caffeine comparison tool allows users to stack up to four beverages and see cumulative caffeine intake and decay profiles.

What changes the number for McDonald's McCafé Latte (Medium)

The 110 mg value is specific to the medium (350 ml) McCafé Latte, but McDonald's offers multiple sizes. The caffeine content will differ primarily because the number of espresso shots and the total volume change. While McDonald’s does not publicly disclose exact shot counts, a common industry practice is that a small latte may use 1 shot, a medium 1 or 2, and a large 2 shots. For example, if the medium contains 1 shot, scaling down to a small (around 250 ml) could yield roughly 71 mg, while a large (around 470 ml) might contain 142 mg, assuming a single shot provides the same caffeine output. However, these are approximations; actual caffeine amounts can deviate due to the automatic espresso machine’s calibration and the specific coffee blend used. In some international markets, the recipe may differ, so travelers should check local nutritional information.

Another significant variant is the decaf McCafé Latte. Decaffeinated coffee is not completely caffeine-free; an FDA guideline permits up to 2.5% of the original caffeine content. A decaf latte of equivalent size could contain anywhere from 2 to 5 mg of caffeine, depending on the decaffeination process. McDonald’s lists its decaf coffee as having 2–5 mg per 473 ml serving, so a medium decaf latte would likely fall in that lower range. For consumers who need to avoid caffeine altogether due to medical advice or pregnancy, it is worth noting that even “decaf” can contribute a small amount.

Batch-to-batch variations in coffee beans also play a role. Coffee caffeine content varies with the species (Arabica vs. Robusta), growing conditions, roasting level, and brewing method. McDonald’s uses 100% Arabica beans, which typically contain about half the caffeine of Robusta beans. Roasting darker reduces caffeine slightly by mass, but the difference is marginal in a prepared drink. Additionally, extraction efficiency in espresso machines can vary with grind size, tamping pressure, and water temperature, leading to a natural range of ±10–15% in caffeine per shot. Therefore, while 110 mg is a representative value, any single latte might deliver between 95 and 125 mg.

Other modifications, such as requesting an extra shot of espresso or choosing a flavored syrup, affect caffeine only if the espresso quantity changes. Flavor syrups contain no caffeine. McDonald’s also offers a caramel version; the caffeine remains the same as the standard latte unless the recipe alters the number of shots. The iced McCafé Latte uses the same espresso base and milk, so its caffeine content matches the hot version of equivalent size. In the US, the McCafé Latte is prepared with whole milk by default, but substituting non-dairy milks does not alter caffeine. Understanding these variables helps consumers gauge their intake more accurately, especially if they are monitoring their daily consumption.

Where this figure comes from

The caffeine value of 110 mg for a medium McDonald’s McCafé Latte is sourced from McDonald’s official nutrition information. Fast-food chains regularly publish detailed nutritional data, which are typically verified by third-party laboratories and made available on their websites and in-store materials. This figure is also cross-checked with entries in the USDA FoodData Central where applicable, and with academic literature on caffeine content in commercial espresso beverages. Discrepancies between different databases often arise because of laboratory testing methodology, seasonal blending adjustments, and occasional recipe changes. For instance, McDonald’s may source its Arabica beans from multiple regions, and while their roasting profile and espresso extraction parameters aim for consistency, small batch-to-batch variations are inevitable.

It is not uncommon to find alternative numbers online, ranging from 100 mg to 120 mg for the same drink. Older or crowd-sourced databases may reflect a previous era when a medium latte had a different size or shot count. We monitor official disclosures and, when a chain updates its published data, we revise our figures accordingly. In 2024, McDonald’s US confirmed the 110 mg value for the medium McCafé Latte, and we reflect that here. The broader context of caffeine guidance referenced on this page comes from the U.S. Food and Drug Administration and the European Food Safety Authority’s 2015 scientific opinion, both of which represent the best-available consensus on safe intake levels. If you encounter a figure that differs significantly from ours, we invite you to consult our open caffeine dataset, where we document data sources and revision histories to maintain full transparency.

Bottom line

A medium McDonald’s McCafé Latte provides 110 mg of caffeine, making up 28% of the recommended daily maximum of 400 mg. This amount is equivalent to roughly 1.1 cups of standard drip coffee and positions the drink as a moderate caffeine option compared to many other coffee chain beverages. After consumption, caffeine levels decay with a half-life of about 5.7 hours, leaving approximately 53 mg after 6 hours and 26 mg after 12 hours — a relatively gentle decline that can still affect sleep if consumed too late in the day.

For most healthy adults, up to three such lattes can be accommodated within the daily limit, whereas pregnant individuals and adolescents should exercise more caution given the 200 mg and 100 mg respective recommendations. Variations in size, decaffeination, and individual metabolism mean the actual dose may vary modestly, but the 110 mg figure is the best current estimate based on McDonald’s official nutrition data. When used alongside personal tolerance and timing tools, this number provides a reliable foundation for making informed decisions.
