What is drip coffee? Drip vs pour-over vs filter coffee

Is drip coffee the same as pour-over?

Pour-over is a kind of drip coffee, made by hand. Wikipedia describes pour-over as manually brewed drip coffee, poured over a coffee bed in a filter-lined cone, trapezoid or cylinder.

In everyday American use, "drip coffee" usually means a machine. Counter Culture defines pour-over as any brew where you pour water by hand and it passes through the coffee before falling into a server. A machine does the same thing on a timer, with less control over how the water lands.

Where did drip coffee come from?

The modern method starts with the paper filter. Melitta Bentz invented the first commercial paper coffee filter in Germany in 1908, according to Wikipedia. She wanted to remove the bitter taste caused by overbrewing.

Electric machines followed. Wikipedia says Willy Brand built an automatic drip brewer with circular paper filters in Switzerland in 1944. The Wigomat, patented in Germany in 1954, was one of the first electric drip brewers.

In the US, the turning point came in the 1970s. Wikipedia says Mr. Coffee, an early electric drip machine, went on sale in the early 1970s, and that drip makers largely replaced percolators during that decade.

What makes a good drip coffee machine?

A good machine holds the water hot enough and long enough, and wets the grounds evenly. The Specialty Coffee Association (SCA) tests this in its Certified Home Brewer program.

The SCA's 2021 home brewer standard sets a slurry range of 90 to 96°C (194 to 205°F). The brew must reach it once a third of the water is in. It must stay in that range for the rest of the cycle. The standard's test ratio is 55 g of coffee per kilogram of water.

Moccamaster, whose brewers carry the certification, summarizes the program as a 4 to 8 minute brew time. It also says the brewed coffee must stay at 80 to 85°C (176 to 185°F) for at least 30 minutes afterwards.

Why does drip coffee taste different from French press?

Drip coffee is a percolation brew, and French press is an immersion brew. Coffee ad Astra explains the key difference: percolation extracts with clean water, while immersion water grows more concentrated as it sits.

Because fresh water keeps replacing the brewed liquid, extraction in a drip brew stays fast. Wikipedia notes that paper filters also remove oils. The result is usually a lighter, cleaner cup than a French press.

What grind size does drip coffee need?

Usually a medium grind, adjusted by how long the water takes to pass through. Counter Culture's pour-over guide uses brew time as the guide, with most pour-overs landing at 3 to 4 minutes.

Its rule of thumb is simple. If water runs through in two minutes, grind finer. If it takes five, grind coarser. The same logic applies to a machine: a basket that floods or drips slowly is telling you about grind.

For starting settings on your grinder, see drip grind settings by grinder, or read why your grinder matters more than your brewer.

How much coffee should you use for drip?

Most guides land between 1:14 and 1:20 coffee to water by weight. Counter Culture gives that range and suggests 1:17 as a start for cone and flat-bottom brewers.

The SCA's test ratio of 55 g per kilogram works out to about 1:18. If you want to scale a batch for a 10-cup carafe, the brew calculator does the math. Our coffee to water ratio guide covers the reasoning in more depth.
