How Much Caffeine Is in Your Drink?

Key Takeaways

• At 62.5 mg per ounce, espresso delivers the most caffeine by far—nearly 4x more than brewed coffee.
• Matcha has 8.75 mg of caffeine per ounce, beating both black and green brewed tea at 4–6 mg.
• Even decaffeinated coffee has trace caffeine: 0.4-0.6 mg per ounce.

Size Matters

A common misconception is that espresso-based beverages, like lattes and americanos, have more caffeine than coffee. While espresso shots do pack a punch, a cup of brewed coffee often has more caffeine overall.
