Monster vs Peace Tea: which has more caffeine?

Monster has more caffeine than Peace Tea on both counts: 160mg per 16 oz can against 23mg per 23 oz can, and about 10mg per fluid ounce against 1. 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.

Monster vs Peace Tea: the numbers

Sources: Monster's figure is verified in our Monster caffeine guide against Caffeine Informer (source); Peace Tea's figure is verified in our Peace Tea guide against Caffeine Informer (source).

The concentration gap is the striking part: Monster packs roughly 10 times the caffeine per ounce. Sipping speed matters at that density; a 16 oz can 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 Monster 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.
