A typical one-ounce serving of espresso contains approximately 63 milligrams of caffeine. This amount can vary slightly depending on factors such as the coffee bean variety, roast level, and brewing method. For comparison, a standard eight-ounce cup of brewed coffee generally contains between 95 and 200 milligrams of caffeine.
Understanding the caffeine content of espresso is essential for managing caffeine intake and making informed beverage choices. This knowledge allows individuals to moderate consumption based on personal sensitivity levels and desired effects. Historically, espresso’s concentrated caffeine content contributed to its popularity as a quick and effective stimulant. Today, this characteristic remains a key element of its widespread appeal.
