Espresso was invented in the early 20th century in Italy, with the first machines appearing around 1901. Compared to coffee’s long history, that’s pretty recent. In Italy, people often drink espresso standing at the bar in just a few sips—it’s more of a quick ritual than a long sit-down experience.
Espresso is a strong, concentrated coffee brewed by forcing hot water through finely ground coffee under high pressure. A single shot of espresso has about 60–80 mg of caffeine, while a regular cup of drip coffee often has 90–150 mg. Espresso just tastes stronger because it’s concentrated. Espresso requires a very fine grind—almost like powdered sugar. Too coarse or too fine, and the shot will taste either weak or bitter.
