Aspire Energy vs matcha: which has more caffeine?

Aspire Energy carries more total caffeine per serving (80mg per 12 oz can vs 60mg per 8 oz cup (1 tsp, ~2g)), but ounce for ounce matcha is actually the stronger drink at about 8mg per fluid ounce against 7. Which one "has more caffeine" depends on whether you measure the container or the concentration.

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.

Aspire Energy vs matcha: the numbers

Sources: Aspire Energy's figure is verified in our Aspire Energy caffeine guide against Aspire / Caffeine Informer (source); matcha's figure is verified in our matcha guide against USDA FoodData Central (per-gram) / compiled (source).

Which one should you pick?

Pick matcha when you want the lighter dose or a slower ramp, and Aspire Energy 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.
