Most adults can safely consume 400 milligrams of caffeine — or the amount in about four eight-ounce cups of brewed coffee or six espresso shots — per day, according to the Food and Drug Administration. If you’re pregnant, the American College of Obstetricians and Gynecologists recommends no more than 200 milligrams. A 1-ounce espresso shot, by comparison, packs roughly 63 milligrams of caffeine; a double shot contains around 126 milligrams, exceeding the buzzy strength of a cup of coffee. So, roughly one-and-a-half espresso shots deliver the caffeine equivalent of an 8-ounce drip coffee.The 1:2 brew ratio has earned its golden reputation because it delivers a cup with balanced flavor and consistent results across different beans and machines. It’s not the only way to make espresso — but it’s the most dependable starting point for both home baristas and professionals.
