How much caffeine is in Starbucks Cold Brew (Grande)?

205 mg of caffeine is in a Starbucks Cold Brew (Grande, 473 ml) according to TrackCaffeine's dataset (/dataset/, accessed 2026-08-02).

Caffeine is a central nervous system stimulant that typically reaches peak blood levels within about 30–60 minutes after drinking, according to the Mayo Clinic (Mayo Clinic, accessed 2026-08-02); in practical terms, the Cold Brew's stimulant effects usually appear within an hour. The drink's concentration is about 43 mg per 100 ml calculated from 205 mg in 473 ml (205 mg ÷ 4.73 = 43.36 mg per 100 ml), with that arithmetic and source noted in TrackCaffeine's dataset (/dataset/, accessed 2026-08-02). Compared with a standard reference cup of drip coffee at 96 mg per 240 ml from the same dataset (/dataset/, accessed 2026-08-02), this Cold Brew equals roughly 2.1 times a 240-ml drip cup, which is the 2.1× figure listed in the dataset (/dataset/, accessed 2026-08-02). The immediate subjective effects—alertness, narrower focus, reduced sleepiness—vary by sensitivity and timing, but onset and magnitude follow the same pharmacokinetic pattern described below.

How long Starbucks Cold Brew (Grande) stays in your system

TrackCaffeine models caffeine elimination as first-order kinetics with a population-average half-life of 5.7 hours (model parameter: half-life = 5.7 h, TrackCaffeine /tools/caffeine-calculator/, accessed 2026-08-02); the mathematical formula used is remaining = dose × 0.5^(hours / 5.7). For this drink that arithmetic looks like: remaining = 205 mg × 0.5^(hours / 5.7) (formula and dose from TrackCaffeine dataset, /dataset/, accessed 2026-08-02).

Using that formula for common intervals gives: at 3 hours: remaining = 205 × 0.5^(3/5.7) = 205 × 0.6948 ≈ 142 mg; at 6 hours: 205 × 0.5^(6/5.7) = 205 × 0.4824 ≈ 99 mg; at 9 hours: 205 × 0.5^(9/5.7) = 205 × 0.3340 ≈ 69 mg; at 12 hours: 205 × 0.5^(12/5.7) = 205 × 0.232 ≈ 48 mg (all calculations based on half-life = 5.7 h, TrackCaffeine /tools/caffeine-calculator/, accessed 2026-08-02). As an example timeline: if the Grande Cold Brew is consumed at 15:00, about 142 mg remains at 18:00, about 99 mg at 21:00, about 69 mg at 00:00, and about 48 mg at 03:00, using the arithmetic above and the TrackCaffeine decay model (/tools/caffeine-calculator/, /dataset/, accessed 2026-08-02).

The 205 mg in this Grande Cold Brew equals 51% of a 400 mg daily guidance value and therefore uses slightly more than half of that nominal limit (51% calculation and base guidance: 205 mg ÷ 400 mg = 0.5125, and the 400 mg guidance is from EFSA (2015)).

The European Food Safety Authority gives 400 mg/day for healthy adults and a 200 mg/day recommendation in pregnancy (EFSA Scientific Opinion on Caffeine, 2015); because this single Cold Brew contains 205 mg it exceeds the 200 mg pregnancy recommendation in the same EFSA report (EFSA, 2015). For sleep timing, Drake et al. (2013) found that a 400 mg dose taken 6 hours before bedtime still reduced total sleep time by more than an hour (Drake et al., 2013), so using the half-life arithmetic above is prudent: if a 473-ml Cold Brew is consumed at 17:00, about 99 mg remains at a 23:00 bedtime (calculation and model: 205 mg × 0.5^(6/5.7) ≈ 99 mg, TrackCaffeine /tools/caffeine-calculator/, accessed 2026-08-02). If a precise cutoff is needed for planning sleep, run the numbers for your timing with our last-cup tool (Last Cup Before Bed, accessed 2026-08-02) or use the half-life calculator (Caffeine Half-Life Calculator, accessed 2026-08-02).

Special populations: pregnant people should note the EFSA pregnancy limit of 200 mg/day (EFSA, 2015), adolescents and people with heightened sensitivity will often need much lower totals (sensitivity caveat based on clinical guidance summarized by the Mayo Clinic, Mayo Clinic, accessed 2026-08-02), and anyone tracking intake by weight can consult our safe daily limit tool (Safe Daily Limit by Body Weight, accessed 2026-08-02).

Within Starbucks large-format drinks in our dataset, the Cold Brew’s 205 mg places it below the brewed Pike Place at 310 mg and slightly below an Americano at 225 mg (comparisons: Pike Place Brewed, 310 mg, accessed 2026-08-02; Caffè Americano, 225 mg, accessed 2026-08-02). It is higher than many milk-based Grande lattes and mochas—examples include the Caffè Latte at 150 mg and the Caffè Mocha at 175 mg in our dataset (Caffè Latte, 150 mg, accessed 2026-08-02; Caffè Mocha, 175 mg, accessed 2026-08-02).

Against generic coffee benchmarks, the Cold Brew equals about 2.1 standard 240-ml drip cups (96 mg per 240 ml reference in our dataset), which illustrates that Cold Brew is a concentrated, higher-caffeine option compared with a single drip coffee cup (2.1× figure and drip reference: TrackCaffeine /dataset/, accessed 2026-08-02).

What changes the number for Starbucks Cold Brew (Grande)

What moves the 205 mg figure for a Starbucks Cold Brew? The three main variables are brew concentration, serving size/dilution, and product variant (for example, nitro or added milks and syrups); this description and the examples below are based on observed variation in our open dataset (/dataset/, accessed 2026-08-02). Cold brew is made by long steeping coarse grounds in cold water; stronger concentrate or less dilution raises the mg per 473 ml, while dilution or added dairy reduces mg per serving proportionally (process description and expected direction of change, TrackCaffeine /dataset/, accessed 2026-08-02).

Measured variation within similar Starbucks Grande drinks in our dataset illustrates real differences: Starbucks Pike Place Brewed (Grande) measures 310 mg while a Starbucks Caffè Latte (Grande) measures 150 mg, showing that brew method and formula matter (numbers and links: Starbucks Pike Place Brewed (Grande), 310 mg, accessed 2026-08-02; Starbucks Caffè Latte (Grande), 150 mg, accessed 2026-08-02). One shot of Starbucks Blonde Espresso is 85 mg per 30 ml in our dataset, which explains why milk-forward drinks can sit lower in total caffeine (Starbucks Blonde Espresso (shot), 85 mg, accessed 2026-08-02).

• Batch-to-batch: beans, roast, and extraction time cause lab-measured variation; our open dataset documents these laboratory and menu-source differences (/dataset/, accessed 2026-08-02).
• Serving changes: ordering a Trenta or a double-strength concentrate will change the 205 mg number by straightforward proportion (serving-size arithmetic and caveat: TrackCaffeine /dataset/, accessed 2026-08-02).
• Decaf options: decaffeinated cold brew is available at some shops and follows the decaf guidance in our decaf pages (see Starbucks Decaf: How Much Caffeine is Really in Decaf?, accessed 2026-08-02).

Because of these variables, the 205 mg figure is a best single-value estimate for a Grande Cold Brew in our dataset, not an absolute laboratory certainty for every cup; the page updates when new batch-level laboratory data or official manufacturer disclosures change the figure (/dataset/, accessed 2026-08-02).

Where this figure comes from

The 205 mg number shown on this page comes from the TrackCaffeine open dataset entry for Starbucks Cold Brew (Grande) and reflects the best available menu data and laboratory reports we have collected; the dataset record is published at /dataset/ and was accessed for this page on 2026-08-02 (TrackCaffeine /dataset/, accessed 2026-08-02). Published values disagree across vendors and laboratory assays because extraction method, bean blend, and dilution vary; where Starbucks or laboratory disclosures change, we update the dataset entry and this page (/dataset/, accessed 2026-08-02).

We link to external scientific guidance when giving health thresholds: the 400 mg/day guidance and the 200 mg/day pregnancy recommendation are from EFSA (2015), and sleep-effect timing cited here references Drake et al. (2013); those external sources are the basis for the daily- and sleep-context statements on this page (EFSA, 2015; Drake et al., 2013).

Bottom line

Starbucks Cold Brew (Grande, 473 ml) contains 205 mg of caffeine (TrackCaffeine dataset, /dataset/, accessed 2026-08-02), which is about 43 mg per 100 ml and equals roughly 2.1 standard 240-ml drip cups (96 mg per 240 ml reference, TrackCaffeine /dataset/, accessed 2026-08-02). That 205 mg is 51% of the 400 mg/day guidance from EFSA (2015), and using a population half-life of 5.7 hours (TrackCaffeine /tools/caffeine-calculator/, accessed 2026-08-02) leaves approximately 142 mg at 3 hours, 99 mg at 6 hours, 69 mg at 9 hours, and 48 mg at 12 hours after consumption (arithmetic shown earlier).
