A standard single shot of espresso, which is about 1 ounce (30 milliliters), typically contains approximately 63 to 75 milligrams of caffeine. The average figure often cited is around 64 to 75 mg per shot, though it can vary from about 29 mg up to 100 mg depending on factors like the type of coffee beans, roast level, grind size, and brewing method
. Key points:
- A single espresso shot usually has about 63-75 mg of caffeine.
- Variability depends on bean type (Robusta has more caffeine than Arabica), roast (lighter roasts have slightly more caffeine), and preparation details.
- A double shot (doppio) typically contains about 130-150 mg of caffeine
In comparison, an 8-ounce cup of brewed coffee contains roughly 96 mg of caffeine, so espresso is more concentrated but served in smaller volume
. Thus, the caffeine content in a single espresso shot is generally around 63-75 mg, with some variation based on preparation and coffee type.
