Starbucks bottled cold brew vs Red Bull: which has more caffeine?

Starbucks bottled cold brew has more caffeine than Red Bull on both counts: 180mg per 11 oz bottle against 80mg per 8.4 oz can, and about 16mg per fluid ounce against 10. 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.

Which one should you pick?

Pick Red Bull when you want the lighter dose or a slower ramp, and Starbucks bottled cold brew 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.
