matcha has more caffeine than Peace Tea on both counts: 60mg per 8 oz cup (1 tsp, ~2g) against 23mg per 23 oz can, and about 8mg per fluid ounce against 1. The serving sizes differ, so the table below shows both ways of counting.
matcha vs Peace Tea: the numbers
| matcha | Peace Tea | |
|---|---|---|
| Caffeine per serving | 60mg per 8 oz cup (1 tsp, ~2g) | 23mg per 23 oz can |
| Caffeine per fl oz | 7.5mg | 1.0mg |
| Servings to reach 400mg (FDA context) | 6.7 | 17.4 |

The concentration gap is the striking part: matcha packs roughly 8 times the caffeine per ounce. Sipping speed matters at that density; a 8 oz cup (1 tsp, ~2g) finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick Peace Tea when you want the lighter dose or a slower ramp, and matcha 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.
