I use a French press at my FIL's house because I am the only one there drinking coffee. In my experience, and a coworker noted the same thing, it takes more coffee grounds to make French press coffee. At home I use 1/2 cup of coffee in my Hamilton Beach Brew Station to make a carafe's worth of coffee. I have to use a 1/2 cup of coffee in my French press to make about a 1/2 carafe's worth of coffee.
I have reason to use the Melita-style pourover coffee making system on weekends when I am doing my ren faire stuff. This style uses closer to the 1/2 cup for a carafe's worth of coffee. ETA: It does take more time than French press coffee.
