Caffeine in a Double Espresso vs a Caffeine Pouch
Short answer: A double shot of espresso contains roughly 126mg of caffeine (2×63mg). A Nectr Energy pouch delivers 50mg — roughly 40% of a double espresso dose, but with faster onset via sublingual absorption.
The precise caffeine content
- Single shot (1oz espresso): 63mg caffeine (USDA average).
- Double shot (2oz): 126mg caffeine.
- Ristretto double: ~80–100mg (shorter pull, less extraction).
- Lungo double: ~140–160mg (longer pull, more extraction).
Why espresso varies
Caffeine extraction depends on:
- Bean origin: Robusta has 2× the caffeine of Arabica.
- Roast level: Lighter roasts retain slightly more caffeine per gram.
- Grind size and dose: A 9g single pulls less than an 18g double.
- Extraction time: Longer pulls = more caffeine.
- Water temperature and pressure: Standard parameters vary cafe to cafe.
Cafe-to-cafe variation can be 30%+ in caffeine content for "the same drink."
