    Coffee beans generally only have enough caffeine for one use.  Caffeine content from a coffee bean depends on the plant the bean is harvested from.  Arabica beans from Central and South America produces about 1.1% caffeine.  The stronger robusta beans from Indonesia and Africa produces around 2.2% caffeine.  For Americans a normal cup of coffee averages about 75 mg of caffeine.  However, preparation and size of the cup will make a different in the amount of caffeine.
