espresso has more caffeine than matcha on both counts: 63mg per 1 oz shot against 60mg per 8 oz cup (1 tsp, ~2g), and about 63mg per fluid ounce against 8. The serving sizes differ, so the table below shows both ways of counting.
These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.
matcha vs espresso: the numbers
| matcha | espresso | |
|---|---|---|
| Caffeine per serving | 60mg per 8 oz cup (1 tsp, ~2g) | 63mg per 1 oz shot |
| Caffeine per fl oz | 7.5mg | 63.0mg |
| Servings to reach 400mg (FDA context) | 6.7 | 6.3 |

The concentration gap is the striking part: espresso packs roughly 8 times the caffeine per ounce. Sipping speed matters at that density; a 1 oz shot finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick matcha when you want the lighter dose or a slower ramp, and espresso when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
