The Filter coffee (also known as American coffee) is a very simple system to brew coffee. The water in the tank is pushed towards the heating element at the base of the machine. Hot water then passes through a tube, with internal outlet at the top of the machine before passing through the coffee filter. Coarse ground coffee allows the slow passage of water and is collected by a glass or thermal carafe. Drip coffee has a very mild flavour but in fact contains more caffeine than espresso as the water remains in contact with the coffee for a longer period of time thus absorbing its aroma, oils and caffeine.
