In automatic coffeemakers hot water drips onto coffee grounds which are held in a filter, this allows the water to seep through the coffee, extracting the oils and essences and dripping through the filter into a pot.

Coffee percolator’s use steam pressure to force boiling water through a filter and into a chamber above. Water seeps through the grounds extracting the flavour and this process is repeated until the coffee is ready.

French press is a method where ground coffee and hot water are placed in a cylindrical container. A filter, attached to a plunger, is pressed down onto the grounds, forcing them to the bottom and allowing the oils and essences to remain in the container.
