Drip coffee (Wikipedia)

Drip coffee is made by pouring hot water onto ground coffee beans, allowing it to brew. There are several methods for doing this, including using a filter. Terms used for the resulting coffee often reflect the method used, such as drip-brewed coffee, or, somewhat inaccurately, filtered coffee in general. Manually brewed drip coffee is typically referred to as pour-over coffee. Water seeps through the ground coffee, absorbing its constituent chemical compounds, and then passes through a filter. The used coffee grounds are retained in the filter, while the brewed coffee is collected in a vessel such as a carafe or pot.

Water seeps through the ground coffee and the paper filter and is then collected in a container placed below a holder used for drip brewing.
