How to read the caffeine chart
Each row shows a typical serving of a drink and the caffeine it usually contains. Because caffeine depends on the ingredients and how a drink is made, the same drink can land above or below these figures — they're a starting point, not a guarantee.
What changes a drink's caffeine
Three things move the number the most: the bean or leaf (Robusta coffee beans have about twice the caffeine of Arabica), the serving size (a 16 oz coffee has far more than an 8 oz one), and the brew — longer contact with water, as in cold brew, pulls out more caffeine.
