How much caffeine is in different drinks?
Caffeine is the same compound regardless of source, but the amount consumed depends on the drink, serving size and preparation. Open a category for illustrative examples.
ColaOpen caffeine amounts
- 0.5 litres: approximately 47 mg of caffeine
- 1 litre: approximately 94 mg of caffeine
- 1.75 litres: approximately 165 mg of caffeine
The exact amount may vary by brand and product.

EspressoOpen caffeine amount
The caffeine in an espresso may vary considerably depending on the coffee beans, serving size and preparation. Caffeine from coffee also counts toward daily intake.
Energy drinkOpen caffeine amount
Subject to the exceptions set out in the legislation, drinks containing more than 150 mg of caffeine per litre must carry the required high-caffeine warning and state their caffeine content in mg per 100 ml. A typical 250 ml energy drink contains about 80 mg, but check the particular product.

A 300 ml cup of black tea in an earlier MESZ comparison contained 53 mg of caffeine. The amount can vary with the tea, quantity used and steeping time.
These are illustrative values, not fixed amounts for every product. Count caffeine from all sources when calculating daily intake. Caffeine intake and responsible consumption →
Total intake matters
Add up the caffeine amounts from every serving consumed. Even where two drinks contain the same caffeine quantity, they may differ in sugar content, serving size and the speed at which they are consumed.
The EFSA assessment of daily and single-dose caffeine intake is summarised on the Responsible consumption page.
