Brewing Methods Compared

How to choose among nine common brewing methods

Brewing is about using water to extract aroma, acidity, sweetness, and soluble compounds from ground coffee. No brewer is absolutely better or worse; each reveals a different side of coffee.

Various coffee brewers and tasting cups
Different brewers use drip, immersion, or pressure to bring out different layers of flavor.

Pour Over

Hand-poured filter

Hot water flows slowly through ground coffee and a paper filter, with gravity doing the extraction. Usually clean, bright, and clearly layered, it can delicately showcase floral, fruity, acidic, and sweet notes.

French Press

Full immersion

Ground coffee is fully immersed in hot water, then separated with a metal mesh filter. More oils remain in the cup, giving a heavy body and full aroma.

AeroPress

Immersion + pressure

Combines immersion and pressure. With many possible adjustments to grind, water temperature, and time, it can brew anything from light and refreshing to rich and intense.

Espresso

Espresso

Hot water under high pressure passes through finely ground coffee in a short time, extracting a small, concentrated shot—the base of Americanos, lattes, and cappuccinos.

Moka Pot

Stovetop pressure

Steam pressure from heating pushes hot water through the coffee grounds. It is usually stronger than pour-over, ideal for those who like a rich, full-bodied cup.

Siphon

Vacuum brewer

Brews using steam pressure and the vacuum created as it cools, producing a clean, aromatic, and delicately layered coffee.

Cold Brew

Long cold immersion

Steeped in cold or room-temperature water for many hours, it usually tastes mellow, smooth, and noticeably sweet—perfect for iced drinks.

Cold Drip

Slow cold drip

Ice water or cold water drips through the coffee grounds very slowly, gradually completing extraction and often producing concentrated aroma and delicate flavor.

Turkish Coffee

Unfiltered and boiled

Very finely ground coffee is heated with water in a traditional pot without a filter, so the grounds settle in the cup. It is thick and aromatic, and a brewing method with a long history and rich cultural heritage.

Brewing Basics

The Basics of Consistent Brewing

First fix the amount of water, coffee, and time, then adjust the grind based on taste. Sour and thin usually means under-extraction; bitter, dry, and hollow may mean over-extraction.
