The answer often turns on the size of the serving, not the strength of the drink. Red Bull and Monster are equally strong and one delivers twice the caffeine. A flat white is smaller than a latte and carries double. Each page gives the figure per serving, per 100 ml and for the same 12 oz, so you can see which of the two is doing the work.
