Starbucks Caramel Macchiato (Grande)에는 카페인이 얼마나 들어 있나요?

A Starbucks Caramel Macchiato (Grande, 16 fl oz) contains 150 mg of caffeine. This amount comes from two shots of Starbucks’ signature espresso roast, which are poured over steamed milk and vanilla syrup, then topped with a crosshatch of caramel sauce. Neither the milk, the syrup, nor the caramel adds caffeine, so the entire stimulant load is delivered by the espresso.

At 473 ml, the drink’s caffeine concentration is roughly 31.7 mg per 100 ml. By comparison, a standard 240 ml cup of drip coffee brewed at home averages 96 mg of caffeine, or 40 mg per 100 ml. The Caramel Macchiato is therefore slightly less concentrated than plain black coffee, but because it is served in a larger volume, the total caffeine lands at 1.6 times that of an 8-ounce cup of drip. Most people begin to feel the effects—increased alertness, a modest lift in energy—within 15 to 45 minutes. The peak effect occurs around the one-hour mark, after which the body starts breaking down the caffeine through first-order elimination.

With 150 mg, this drink accounts for 38% of the 400 mg daily limit that the U.S. Food and Drug Administration considers safe for most healthy adults. That leaves 250 mg of additional caffeine headroom for the rest of the day, equivalent to about two more 8-ounce cups of coffee or a second Grande Caramel Macchiato with room to spare.

Caffeine follows first-order elimination kinetics, meaning the body removes a constant fraction of the drug per unit time. The population-average half-life—the time it takes for the plasma concentration to drop by 50%—is 5.7 hours in healthy adults. For a 150 mg dose, the amount remaining after any number of hours can be calculated as 150 × 0.5^{(hours / 5.7)}. At 3 hours post-consumption, roughly 104 mg remains (150 × 0.5^0.526 ≈ 104 mg). At 6 hours, the figure drops to about 72 mg. By 9 hours, it is approximately 50 mg, and at 12 hours, only 35 mg is still circulating. These numbers are averages; individual metabolism varies with genetics, liver function, and whether the person is a smoker or takes oral contraceptives, both of which can alter the half-life. A caffeine half-life calculator can model a personal decay curve.

To put that timeline into a real-world context, imagine finishing a Grande Caramel Macchiato at 15:00 (오후 3시). By 18:00, 104 mg of caffeine is still active—more than a single shot of espresso (63 mg). At 21:00, with 72 mg on board, the stimulant effect is roughly equivalent to having recently consumed a small energy drink. By midnight, 50 mg remains, which is more than the caffeine in a 355 ml can of Coke Zero (34 mg). Even at 03:00, 12 hours later, 35 mg lingers. Research by Drake et al. (2013) demonstrated that a 400 mg dose taken six hours before bedtime still reduced total sleep time by more than an hour and increased nighttime awakenings. While 150 mg is a smaller dose, the residual 72 mg at six hours can still interfere with deep sleep in sensitive individuals. For a 23:00 bedtime, finishing this drink no later than early afternoon minimizes sleep disruption.

With 150 mg of caffeine, a single Grande Caramel Macchiato uses 38% of the FDA’s 400 mg daily ceiling for healthy adults. A person could consume two of these drinks in a day and still remain 100 mg below the limit, or have one plus several other modest sources like tea or soda without exceeding the guideline. However, the European Food Safety Authority also recommends that single doses stay at or below 200 mg to avoid potential side effects such as jitteriness or a racing heart, and this drink falls comfortably within that boundary at 150 mg.

For sleep, timing matters. Caffeine blocks adenosine receptors, and even when the stimulant feeling fades, residual caffeine can disrupt deep sleep and reduce total sleep time. For a 23:00 (11 p.m.) bedtime, finishing a Grande Caramel Macchiato by 14:00 (2 p.m.) leaves approximately 50 mg in the system at lights-out—a level that may still fragment sleep in sensitive individuals. Pushing the finish time to 15:00 leaves about 72 mg at 23:00, which is enough to delay sleep onset for many people. The latest cup before bedtime calculator can model a personal cutoff based on typical bedtime and sensitivity. Pregnant individuals and those with certain medical conditions face stricter limits: EFSA advises a maximum of 200 mg per day during pregnancy, so one Grande Caramel Macchiato already accounts for 75% of that allowance. Adolescents should limit caffeine to no more than 3 mg per kilogram of body weight per day, according to EFSA, meaning a 50 kg (110 lb) teenager would reach their daily limit with this single drink.

Individual sensitivity also plays a large role. Genetic variations in the CYP1A2 enzyme mean some people metabolize caffeine twice as slowly as the population average, effectively doubling the half-life. For a slow metabolizer, the 150 mg dose could feel more like 300 mg and linger well into the night. If tolerance is uncertain, starting with a smaller size or a decaf version is a practical way to gauge response.

Among Starbucks’ Grande espresso beverages, the Caramel Macchiato sits at the lower end of the caffeine spectrum. It shares its 150 mg total with the Caffè Latte and Cappuccino, all of which are built on two espresso shots. Drinks that add extra shots or use a different base pull ahead: the Flat White contains 195 mg, the Caffè Mocha has 175 mg, and the Caffè Americano reaches 225 mg. The Cold Brew (205 mg) and the brewed Pike Place (310 mg) are substantially more caffeinated, making the Caramel Macchiato a moderate choice for those who want a noticeable lift without the intensity of a full brewed coffee.

Outside the Starbucks menu, the 150 mg dose compares to a 473 ml can of Monster Energy (160 mg) and is nearly twice the 80 mg in a 250 ml can of Red Bull. It is also 25% more than a Dunkin’ Latte Medium (119 mg). Against a simple cup of home-brewed drip coffee (96 mg per 240 ml), the Grande Caramel Macchiato provides the caffeine equivalent of roughly 1.6 cups. For someone accustomed to a single morning mug of coffee, this drink delivers a slightly larger caffeine hit, though the experience is softened by the sweet, creamy flavor profile.

What sets the Caramel Macchiato apart is not its caffeine strength but its composition. It is one of the few Starbucks drinks where the espresso is poured on top of the milk, creating a layered effect. The caffeine content, however, remains firmly in the middle of the pack—enough to be functional, but not so high that it dominates the daily budget.

The caffeine in a Caramel Macchiato is determined almost entirely by the number and type of espresso shots used. The standard Grande recipe calls for two shots of Starbucks’ signature espresso roast, each contributing approximately 75 mg of caffeine. Any change to the shot count or the espresso blend directly alters the total. The milk, vanilla syrup, and caramel drizzle are caffeine-free, so adjusting those ingredients—such as opting for a non-dairy milk or extra caramel—does not affect the stimulant content.

Size is the most straightforward lever. A Tall Caramel Macchiato (12 fl oz) is built with one espresso shot, yielding roughly 75 mg of caffeine. The hot Venti (20 fl oz) also uses two shots, so it matches the Grande at 150 mg. An iced Venti (24 fl oz), however, receives three shots, pushing the caffeine to approximately 225 mg. Because Starbucks does not publish separate caffeine figures for every size and temperature combination on its website, these numbers are based on the standard shot counts and the average 75 mg per shot; actual totals may differ slightly from visit to visit.

• Blonde Espresso: Substituting Starbucks’ Blonde Espresso—a lighter roast with a higher caffeine content per shot—raises the caffeine. A single Blonde shot contains 85 mg, so a Grande made with Blonde espresso would deliver 170 mg, a 13% increase.
• Decaf: A decaf Caramel Macchiato uses decaffeinated espresso shots, which typically retain 3–15 mg of caffeine per shot. A Grande decaf would therefore contain between 6 mg and 30 mg, making it a low-caffeine option suitable for late-day consumption.
• Extra shots: Requesting an additional shot adds roughly 75 mg (or 85 mg for Blonde), so a Grande with three signature shots would contain about 225 mg.

Even under the standard recipe, shot-to-shot variation exists. The caffeine content of an espresso shot can fluctuate by ±10% or more depending on the coffee bean harvest, roast profile, grind size, and the barista’s technique. The 150 mg figure is therefore best understood as a reliable midpoint, not a laboratory-grade measurement for every cup. Starbucks updates its nutrition information periodically, and independent lab tests sometimes report slightly different values; the number on this page reflects the most recent data published by the company.

The 150 mg caffeine figure for a Grande Caramel Macchiato comes directly from the nutrition information published by Starbucks on its official website and in-store menus. Starbucks, like other large coffee chains, periodically commissions laboratory analyses of its beverages to ensure accuracy and updates the numbers when recipes or bean blends change. The value on this page reflects the most recent data made publicly available by the company. It is part of our open caffeine dataset, which aggregates manufacturer-reported caffeine content for thousands of drinks and is updated whenever a brand releases new information.

Different sources sometimes report slightly different numbers for the same drink. The USDA FoodData Central, for example, may list a generic “latte with caramel” with a different caffeine value because it tests a composite of samples from multiple outlets or uses a different serving size. Independent lab tests of individual store purchases can also show variation due to natural shot-to-shot fluctuation. We treat the manufacturer’s own published figure as the most authoritative reference for a branded product, but we acknowledge that any single cup may deviate by a few milligrams. If Starbucks were to reformulate the Caramel Macchiato—by changing the default shot count, for instance, or by switching to a different espresso roast—we would update this page promptly to reflect the new official number.

요약

A Starbucks Grande (16 fl oz) Caramel Macchiato contains 150 mg of caffeine, supplied entirely by its two shots of espresso. That is equivalent to roughly 1.6 eight-ounce cups of drip coffee and accounts for 38% of the FDA’s 400 mg daily maximum for healthy adults. The drink sits in the moderate range among Starbucks offerings—matching the Caffè Latte and Cappuccino, and well below the Pike Place Brewed Coffee (310 mg) or Cold Brew (205 mg). After six hours, about 72 mg of caffeine remains in the body, so finishing one by mid-afternoon helps protect sleep. Pregnant individuals should note that this single drink provides 75% of the EFSA’s recommended 200 mg daily limit during pregnancy. The figure is based on Starbucks’ official nutrition data and reflects the standard recipe; customizations like Blonde espresso or extra shots will raise the total.
