How Much Caffeine Is In A Shot Of Espresso? Is It More Or Less Caffeine Than A Cup Of Drip Coffee?

Q: A guy at work swears that there is actually more caffeine in a cup of coffee than a shot of Espresso.

A: He's right - IF you are talking about normal servings sizes. In other words, a cup of drip coffee is typically 8 oz and contains approx. 145 mg of caffeine, whereas a shot of Espresso is typically 1.5 oz, and contains approx. 77 mg of caffeine. If you have equal measures of drip coffee and Espresso (i.e. 1 oz. of each), Espresso shoots to the front with 51.33mg of caffeine per ounce as opposed to drip which is a mere 18.13mg of caffeine per ounce. If you want information on other drinks, check out the Caffeine Database at: is "regular coffee", just roasted differently than most drip coffees, although it is used in drip as well. concentrated in the shot, it's roughly equivalent in caffeine content, but Espresso roasted beans, when brewed in drip form, have slightly less caffeine than regular coffee. The roasting time to make it is slightly longer than a breakfast blend of coffee (the lighter the roast, the more caffeine [less roasting time] and the darker [bolder] have less). Think of it as roasting out the caffeine content. Espresso falls into the category of "bold" in the spectrum of mild/medium/bold/extra bold 1.5 ounces of Espresso has 77mg of caffeine. 8 ounces of drip coffee has 145 mg of caffeine. So, technically a serving of drip coffee has more caffeine per serving, but Espresso has more milligrams of caffeine per ounce.
