It doesn't have to. The thing that I like about the Aeropress is how convenient it is to control so many variables of extraction, including but not limited to:
dwell time
dose
water temperature
pressure
If you think you need to use more coffee, then there is something wrong. My guess would be that the "something wrong" would be the instructions included with the Aeropress.
