I had to look it up, and apparently coffee as either a brewed cup, or espresso shot has between 100-200 mg of caffeine. So the amount of caffeine in the can isn't out of range for what would be expected of a caffeinated energy drink.
However, we don't require that coffee have a label showing how much caffeine is in it either.
