How much caffeine is in Nitro cold brew?

One 240 ml serving of nitro cold brew contains 215 mg of caffeine, according to our open dataset (/dataset/).

Nitro cold brew is cold-brewed coffee infused with nitrogen for a creamy texture, and that 215 mg works out to 89.6 mg per 100 ml as reported in our open dataset (/dataset/), which is higher in concentration than a standard 240 ml cup of drip coffee at 96 mg per 240 ml in the same dataset.

At 215 mg the shot is roughly 2.2 times a single 240 ml cup of drip coffee (96 mg per 240 ml) as shown in our open dataset (/dataset/), and that concentration commonly produces alertness, reduced perception of effort and narrowed attention for most adults within 15–45 minutes after ingestion, according to clinical caffeine reviews summarized by the Mayo Clinic (Mayo Clinic caffeine chart) and the FoodData Central evidence base (USDA FoodData Central), which document acute stimulant effects after typical caffeinated doses.

How long Nitro cold brew stays in your system

The elimination of caffeine from blood follows first-order kinetics with a population-average half-life of 5.7 hours; using that half-life the remaining caffeine after t hours is calculated as remaining = dose × 0.5^(t / 5.7), where the half-life figure (5.7 hours) is the model parameter used on TrackCaffeine and described in our tools (/tools/caffeine-calculator/).

For a 215 mg dose the arithmetic is: 3 h → 215 × 0.5^(3/5.7) = 215 × 0.5^0.526315789 ≈ 215 × 0.699 = 150 mg (rounded to 149 mg in our decay summary), 6 h → 215 × 0.5^(6/5.7) = 215 × 0.5^1.052631579 ≈ 215 × 0.489 = 105 mg (rounded to 104 mg), 9 h → 215 × 0.5^(9/5.7) = 215 × 0.5^1.578947368 ≈ 215 × 0.343 = 74 mg (rounded to 72 mg), 12 h → 215 × 0.5^(12/5.7) = 215 × 0.5^2.105263158 ≈ 215 × 0.240 = 52 mg (rounded to 50 mg); these calculations use the 5.7-hour half-life that underpins the site calculator (/tools/caffeine-calculator/) and our open dataset (/dataset/).

As an applied example: if a person drinks this 240 ml serving at 15:00, roughly 150 mg remains at 18:00, about 105 mg remains at 21:00, about 74 mg remains at 00:00, and about 52 mg remains at 03:00, using the first-order half-life model (5.7 hours) described on the site (/tools/caffeine-calculator/) and the dose value in our dataset (/dataset/); these residual amounts are what the model estimates are still present in the body, not clinical thresholds for symptoms.

This 215 mg serving uses 54% of the 400 mg daily guidance for healthy adults; that 400 mg/day figure is the U.S. Food and Drug Administration's recommendation (FDA, 400 mg/day, https://www.fda.gov/consumers/consumer-updates/spilling-beans-how-much-caffeine-too-much) and the 54% share is calculated from the 215 mg dose in our open dataset (/dataset/).

If aiming to stay beneath 400 mg per day (FDA, https://www.fda.gov/consumers/consumer-updates/spilling-beans-how-much-caffeine-too-much), one 215 mg serving plus a 240 ml cup of drip coffee at 96 mg (our open dataset, /dataset/) would total 311 mg, leaving about 89 mg before reaching 400 mg; these are simple arithmetic totals using the dataset values.

For sleep timing: using the half-life model with t½ = 5.7 hours (model used on the site and described in our tools, /tools/caffeine-calculator/), a 215 mg dose consumed at 18:00 leaves about 105 mg at 00:00 and about 52 mg at 06:00, and experimental sleep studies show that 400 mg taken 6 hours before bedtime reduced total sleep time by over an hour in one clinical study (Drake et al., 2013) which underscores why many people use the site tool for latest-cup planning (/tools/last-cup-before-bed/).

Caveats for sensitive groups: pregnant people are commonly advised to limit caffeine to 200 mg per day (EFSA Scientific Opinion, 2015, https://www.efsa.europa.eu/en/efsajournal/pub/4102), so a single 215 mg serving exceeds that 200 mg pregnancy guidance when measured against our dataset dose (/dataset/); adolescents and people with cardiovascular or anxiety disorders should consult a clinician because recommended limits differ and sensitivity varies by individual, per clinical guidance summarized by Mayo Clinic and regulatory reviews (Mayo Clinic caffeine chart; EFSA Scientific Opinion, 2015).

Within the brewed-coffee category in our dataset, nitro cold brew at 215 mg per 240 ml (our open dataset, /dataset/) is higher than drip coffee at 96 mg per 240 ml and higher than cold brew at 200 mg per 240 ml in the same dataset, which positions nitro cold brew among the stronger brewed entries recorded.

Comparatively, a 240 ml pour over registers at 145 mg per 240 ml and a 240 ml French press at 107 mg per 240 ml in our open dataset (/dataset/), so the 215 mg nitro dose is substantially above those common brewed methods and slightly above the straight cold brew entry (200 mg per 240 ml) in our dataset; this indicates that nitro servings often use a concentrate or recipe that yields a higher caffeine concentration than many manual-brew methods.

If a reader wants a side-by-side numeric comparison, the site comparison tool can be used to place this drink directly against others (/tools/caffeine-comparison/) and the cold-brew reference page provides context for the close 200 mg per 240 ml cold brew value in our dataset (/caffeine-in/cold-brew/).

What changes the number for Nitro cold brew

The 215 mg figure is an average for a 240 ml serving recorded in our dataset and does not mean every nitro cold brew is identical; our open dataset (/dataset/) shows that serving size, extraction strength and concentration all move the number.

Two main factors change the caffeine load: total brewed-strength (the coffee-to-water ratio and the beans used) and serving volume; for example, a 240 ml cold brew in our data is 200 mg per 240 ml while a 240 ml pour over is 145 mg per 240 ml, both values listed in our open dataset (/dataset/), which illustrates how extraction method and recipe change caffeine in the same cup volume.

Other practical sources of variation include bean origin and roast (light roasts can contain more soluble caffeine per gram than dark roasts in some analyses reported to USDA FoodData Central), extraction time for the concentrate, the dilution used before nitro infusion, and whether a location uses a single- or double-strength concentrate; our open dataset (/dataset/) aggregates samples and therefore gives a representative but not universal single-number estimate.

• Decaffeinated variants: the dataset gives decaf coffee at 3 mg per 240 ml (/dataset/), so a nitro-style decaf will be near that 3 mg per 240 ml figure unless a nonstandard concentrate is used.
• Small and large sizes: a proportional increase in volume raises total mg linearly; doubling the 240 ml dose doubles the mg reported in our dataset (/dataset/).

Because of these variables the single reported value is best treated as a reliable central estimate for a 240 ml nitro cold brew in our collection, with real-world samples commonly varying by ±20% or more depending on recipe and barista practice, as reflected by comparisons across beverage entries in our open dataset (/dataset/).

Where this figure comes from

The 215 mg value for 240 ml nitro cold brew shown here is the aggregated figure recorded in our open dataset for that named drink and serving size, which is why we cite the dataset when reporting the numeric value (/dataset/); other published compilations such as USDA FoodData Central and manufacturer reports may give different single-serving numbers because their sampling methods, serving definitions and laboratory assays differ (USDA FoodData Central, https://fdc.nal.usda.gov/).

We will update the page and alter the reported mg if new, verifiable analytical measurements are submitted to our open dataset or if peer-reviewed sources report materially different averages for the same 240 ml serving and preparation; methodological differences (concentrate dilution, bean selection, roast and extraction) are the most common reasons for disagreement between sources and would trigger a change in our stated estimate.

Bottom line

A 240 ml (8.1 fl oz) nitro cold brew contains 215 mg of caffeine according to our open dataset (/dataset/), which is 89.6 mg per 100 ml and equals about 2.2× a 240 ml drip coffee at 96 mg in the same dataset; that single serving is 54% of the FDA 400 mg/day guidance (FDA, https://www.fda.gov/consumers/consumer-updates/spilling-beans-how-much-caffeine-too-much), and using a 5.7-hour half-life model the remaining caffeine is approximately 150 mg at 3 hours, 105 mg at 6 hours, 74 mg at 9 hours and 52 mg at 12 hours after ingestion (model and dose from our tools and open dataset, /tools/caffeine-calculator/, /dataset/).
