A standard single shot of espresso coffee has about 63–75 mg of caffeine , though it can range roughly from 30 up to 100+ mg depending on how it is made.

Quick Scoop

  • A typical espresso shot (about 1 oz / 30 ml) is usually quoted at around 63 mg of caffeine.
  • Many modern cafes and brands measure closer to 70–80 mg per shot , with an average around 75 mg.
  • In real‑world tests, single shots have been found anywhere from about 30 mg to over 100 mg , depending on grind, dose, beans, and machine.

So if you order:

  • Single shot : expect roughly 60–80 mg.
  • Double shot : about 120–160 mg.

That means a double‑shot latte can easily match or exceed the caffeine in a small cup of regular brewed coffee.
