The amount of caffeine in a cup of coffee can vary greatly depending on the type, method of preparation, and size. Many coffee shops offer drinks with "shot" options—like espresso or other highly-concentrated coffee drinks—which typically contain much higher levels of caffeine. A standard 8-ounce cup of brewed coffee can contain, on average, 95 milligrams of caffeine, according to the Mayo Clinic.
Espresso shots, meanwhile, tend to contain around 64 milligrams of caffeine, though individual coffeeshops serving additional-size shots may pack even higher concentrations of caffeine. Large 14-ounce cups of brewed coffee can contain up to 165 milligrams of caffeine, while cold-brew coffee, made by steeping grounds in cold water, can contain as much as 250 milligrams of caffeine, according to WebMD.
Caffeine levels still vary greatly depending on factors like bean type, brewing time, and size of cup. Studies suggest that light, mellow coffees like Arabica contain less caffeine than dark, bold coffees like Robusta. While the caffeine content in uncooked Robusta beans can be up to twice as high as Arabica beans, Arabica coffee grounds pack more of a caffeine punch when brewed, the World Coffee Research organization reports. Therefore, overall, the amount of caffeine in any given cup of coffee can range wildly.
Overall, knowledge of the amount of caffeine in a standard cup of coffee can help individuals make an informed decision when consuming their favorite hot beverage. From a shot of espresso to a large cup of cold brew, it is important to be aware of the range of caffeine levels present in each type of coffee. Knowing the caffeine level can help ensure that coffee lovers stay safe and informed about their morning pick-me-up.
