The amount of caffeine in coffee drinks, including decaf varieties, can vary greatly depending on how they’re made. Though it may seem stronger, a shot of espresso has less caffeine than a cup of brewed coffee. Black tea, meanwhile, has less caffeine than coffee, green tea has less caffeine than black tea, and chocolate has less than all of them.
This chart shows approximately how much caffeine is in some popular beverages and foods. Keep in mind that there will be a lot of variation in these numbers — light-roast coffee has considerably more caffeine than dark roast, for example.
|Food/Beverage||Serving Size||Amount of Caffeine|
|Dark chocolate||1 ounce (about 1/3 bar)||12 mg|
|Green tea||12 ounces||40–50 mg|
|Black tea||12 ounces||60–70 mg|
|Espresso||1 ounce (one single shot)||75 mg|
|Caffeinated soda||12 ounces||90–115 mg|
|Brewed coffee||12 ounces||150 mg|
|Energy drink||8 ounces||200–300 mg|
