Nitro cold brew delivers about 215 mg of caffeine per 240 ml (8.1 fl oz) serving, the equivalent of roughly 2.2 cups of brewed coffee (a 240 ml cup is about 96 mg). That is about 119 mg more caffeine than a standard cup of coffee.
At 89.6 mg per 100 ml, Nitro cold brew is very concentrated by concentration — the fair way to compare it against drinks of a different size.
How long Nitro cold brew stays in your system
Caffeine leaves the body through first-order elimination with a population-average half-life of about 5.7 hours. Starting from 215 mg, roughly 149 mg is left after 3 hours, about 104 mg after 6 hours, and around 50 mg after 12 hours. Your personal rate varies — smoking speeds it up, pregnancy and some medications slow it down — which is why the calculator below lets you set your own half-life and bedtime.
Nitro cold brew and your daily limit
For most healthy adults the FDA points to about 400 mg of caffeine a day as an amount not generally linked to negative effects. One serving of Nitro cold brew is 54% of that ceiling. Pregnant people are usually advised to stay under about 200 mg a day, and the American Academy of Pediatrics discourages caffeine for children and adolescents. This is general guidance, not medical advice. The easiest way to stay under your own limit is to log every drink — CoffeeLog adds up your real daily total automatically.
