What is the function of a drip coffee maker?

A drip coffee maker functions by pouring hot water over coffee grounds contained in a filter. This method allows water to permeate through the grounds, extracting flavors and oils, which then drip down into a carafe or pot beneath. This process is typically automated; the drip machine heats water to the optimal temperature and evenly distributes it over the coffee grounds, resulting in a consistent brew.

The choice of dripping hot water over coffee grounds is distinctive to drip coffee makers, as it relies on gravity rather than pressure or steeping methods. Brewing by boiling the grounds would result in a much harsher flavor and is not how drip coffee makers are designed to operate. Steeping grounds in water is characteristic of methods like French press or cold brew, where the coffee grounds remain submerged, rather than the brief contact time seen in drip brewing. Lastly, the pressurized method refers to brewing techniques like espresso, which involve forcing water through coffee grounds, again differing fundamentally from the drip process.
