How much caffeine is in Costa Cappuccino (Medio)?

One medium Costa Cappuccino (Medio) contains 277 mg of caffeine.

Caffeine is a central nervous system stimulant; the value 277 mg comes from the TrackCaffeine open dataset (TrackCaffeine dataset, accessed 2026-08-02) and equals about 77 mg per 100 ml (calculated as 277 mg ÷ 360 ml × 100 ml), so this drink is substantially stronger per volume than a standard 240 ml drip cup at 96 mg (Drip coffee, 240 ml, 96 mg; TrackCaffeine dataset, accessed 2026-08-02). The stimulant effects commonly begin within about 15–45 minutes and peak around 30–60 minutes after ingestion (Mayo Clinic, 2018), and a 277 mg dose delivers a sustained measurable amount of caffeine for many hours because of the human elimination half-life (see the half-life section below). For instant logging or trial calculations, use our caffeine half-life calculator at /tools/caffeine-calculator/ or inspect the raw numbers in the public /dataset/ (TrackCaffeine dataset, accessed 2026-08-02).

How long Costa Cappuccino (Medio) stays in your system

This specific dose of 277 mg decays according to a first-order elimination model with a population-average half-life of 5.7 hours (half-life definition: the time it takes for the body to eliminate half of the circulating caffeine). Using remaining = dose × 0.5^(hours / 5.7), the arithmetic for 277 mg is: 3 h → 277 × 0.5^(3/5.7) = 277 × 0.6948 ≈ 192 mg; 6 h → 277 × 0.5^(6/5.7) = 277 × 0.4819 ≈ 134 mg (calculations based on half-life 5.7 h population average; TrackCaffeine dataset dose, accessed 2026-08-02).

If someone drinks this Medio at 15:00, the model predicts about 192 mg remains at 18:00, about 134 mg at 21:00, about 92 mg at 00:00, and about 64 mg at 03:00 (those are the same arithmetic points: 192 mg at 3 h, 134 mg at 6 h, 92 mg at 9 h, 64 mg at 12 h after ingestion), and the sleep-cost study by Drake et al. (2013) found that 400 mg consumed 6 hours before bedtime reduced total sleep time by roughly an hour on average (Drake et al., 2013), so residual amounts from a 277 mg cup taken late afternoon can still affect sleep for sensitive sleepers (Drake et al., 2013).

For personalized timing of the last cup before bed based on your own estimated half-life and bedtime, run the interactive tool at /tools/last-cup-before-bed/ (TrackCaffeine dataset dose used as input if selected).

A single Medio at 277 mg uses about 69% of the 400 mg/day guidance for healthy adults (277 mg ÷ 400 mg = 0.6925 → 69%), where 400 mg/day is the reference for healthy adults reported by EFSA (2015). That means one cup already consumes most of the commonly cited daily cap and leaves roughly 123 mg of margin under the 400 mg recommendation (400 mg − 277 mg = 123 mg; EFSA, 2015).

For sleep planning: because 277 mg yields about 134 mg remaining six hours after ingestion by the model above (277 × 0.5^(6/5.7) ≈ 134 mg; TrackCaffeine dataset dose, accessed 2026-08-02) and Drake et al. (2013) found that 400 mg taken 6 hours before bedtime reduced total sleep time by ≈1 hour, a late afternoon Medio can plausibly shorten sleep for susceptible people (Drake et al., 2013). To estimate your personal latest safe cup before a 23:00 bedtime, run our last-cup calculator at /tools/last-cup-before-bed/ and consider that pregnant people are advised to limit caffeine to about 200 mg/day (EFSA, 2015) and adolescents are recommended to take significantly less than adult guidance (EFSA, 2015).

Those with high sensitivity, pregnancy, medication interactions, or adolescents should exercise caution since a single 277 mg dose exceeds the 200 mg pregnancy guideline (EFSA, 2015) and approaches or exceeds many lower recommended limits; consult a clinician for personalized medical advice (EFSA, 2015).

This Medio Costa Cappuccino at 277 mg sits near the top of common coffee-shop cappuccinos in our dataset: it contains 277 mg versus Starbucks Cappuccino (Grande) at 150 mg (Starbucks Cappuccino (Grande), 473 ml, 150 mg; TrackCaffeine dataset, accessed 2026-08-02), so the Costa Medio has about 127 mg more caffeine than that Starbucks Grande cappuccino at the listed serving sizes. Compared with a straightforward brewed drip cup (240 ml, 96 mg), the Medio equals roughly 2.9 times that amount (2.9× drip coffee equivalent; TrackCaffeine dataset, accessed 2026-08-02), which means the Costa Medio concentrates espresso-based caffeine into a mid-sized cup more densely than many mainstream cappuccinos.

Within the same coffee-shop category the Costa Medio (277 mg) is below Starbucks Pike Place Brewed (Grande) at 310 mg (Starbucks Pike Place Brewed (Grande), 473 ml, 310 mg; TrackCaffeine dataset, accessed 2026-08-02) but above drinks such as Starbucks Caffè Latte (Grande) at 150 mg (Starbucks Caffè Latte (Grande), 473 ml, 150 mg; TrackCaffeine dataset, accessed 2026-08-02) and Dunkin' Original Blend (Medium) at 210 mg (Dunkin' Original Blend (Medium), 414 ml, 210 mg; TrackCaffeine dataset, accessed 2026-08-02).

What changes the number for Costa Cappuccino (Medio)

The single figure 277 mg is an estimate for Costa Cappuccino (Medio) in our dataset and can move for several reasons: espresso shot strength, the number of shots, milk-to-coffee ratio, and shop-to-shop extraction. TrackCaffeine records a Medio as this specific 360 ml serving in one or more sampled locations (TrackCaffeine dataset, accessed 2026-08-02), but shot pull variability can change caffeine by tens of milligrams per serving.

Espresso-based drinks vary because espresso concentration and shot count matter: a single espresso shot is listed in our dataset at 63 mg per 30 ml (Espresso single, 30 ml, 63 mg; TrackCaffeine dataset, accessed 2026-08-02) so swaps in shot number or a stronger pull will alter the final caffeine. A decaffeinated cappuccino variant will typically register under 10–15 mg per serving in many analyses, but decaf values are not recorded for this specific Medio entry (TrackCaffeine dataset, accessed 2026-08-02).

Practical sources of variation include: bean roast and blend (arabica vs. robusta), grind and extraction temperature, and barista shot timing; combined these factors produce a plausible within-category range of roughly ±20–30% for a given café recipe (USDA FoodData Central and TrackCaffeine cross-comparisons, accessed 2026-08-02). If precise logging is required, compare options side-by-side using our comparison tool at /tools/caffeine-comparison/ or inspect the underlying samples in the public /dataset/ (TrackCaffeine dataset, accessed 2026-08-02).

Where this figure comes from

The figure 277 mg is taken from the TrackCaffeine open dataset entry for Costa Cappuccino (Medio) and is cited here as TrackCaffeine dataset (accessed 2026-08-02); published values from other sources differ because of sampling method, serving-size definition, and analytical technique (TrackCaffeine methodology notes, /dataset/, accessed 2026-08-02). We would change the listed value if new verified laboratory assay data or a store-level nutritional update showed a different average for the 360 ml Medio (TrackCaffeine dataset, access and provenance records, 2026-08-02).

For guidance-level comparisons we reference EFSA for the 400 mg/day and pregnancy limits (EFSA, 2015) and rely on Drake et al. (2013) for sleep-timing effects; those references support the contextual recommendations and sleep implications given above (EFSA, 2015; Drake et al., 2013; links: EFSA https://www.efsa.europa.eu/en/efsajournal/pub/4102 and Drake https://jcsm.aasm.org/doi/10.5664/jcsm.3170).

Bottom line

Bottom line: Costa Cappuccino (Medio) contains 277 mg of caffeine (TrackCaffeine dataset, accessed 2026-08-02), which is about 77 mg per 100 ml and equals roughly 2.9 times a 240 ml drip cup at 96 mg (TrackCaffeine dataset calculations). One cup uses about 69% of the 400 mg/day guidance (EFSA, 2015) and, using a 5.7 h half-life model, leaves roughly 134 mg after six hours (277 × 0.5^(6/5.7) ≈ 134 mg; TrackCaffeine dataset dose, accessed 2026-08-02).
