Is There More Caffeine in Espresso Than in Coffee?
Is there really more caffeine in espresso than in a regularly brewed cup of java?
Turns out, it depends on what you call a cup of coffee. An ounce—or one shot—of espresso has 63 milligrams (mg) of caffeine, according to nutritional information from the U.S. Department of Agriculture. By comparison, regular coffee averages 12-16 mg of caffeine per ounce.
So, yes, espresso technically has more caffeine, but in practice no one drinks just one ounce of coffee. You’re likely to have at least 8 ounces, which typically has 95 to 128 mg of caffeine.
