Overview¶

Coffee brewing encompasses a broad range of methods, each applying the same fundamental principles — water contacting ground coffee to dissolve soluble compounds — through different mechanical approaches. Methods are categorised by their primary extraction mechanism: immersion, percolation, pressure, vacuum, cold, boiling, or hybrid. All methods control the same core variables: grind size, water temperature, contact time, agitation, and pressure.

Immersion Brewing¶

Coffee grounds are fully submerged in water for a fixed time, then separated. Characteristics: full body, rounded flavour, heavier mouthfeel.

Methods: French press, cupping, cold brew, cowboy coffee, Turkish coffee (unfiltered immersion).

Typical grind: coarse (except Turkish coffee: very fine).

Percolation (Gravity) Brewing¶

Water passes through a bed of coffee under gravity, with fresh water contacting the grounds continuously and draining into a vessel below. Characteristics: clean, bright flavour; acidity and clarity highlighted.

Methods: Pour Over (V60, Kalita Wave, Chemex, Melitta), batch brew, automatic drip machines.

Typical grind: medium.

Pressure Brewing¶

Water is forced through a compacted coffee bed under pressure. Characteristics: intense flavour; higher concentration; heavier body; crema in espresso.

Methods: espresso (pump and lever), AeroPress (pressure orientation), Moka pot.

Typical grind: fine (espresso), medium-fine (AeroPress, Moka pot).

Vacuum (Siphon) Brewing¶

Extraction is driven by vapour pressure and vacuum created by heating and cooling. Characteristics: exceptionally clean cup; high clarity.

Methods: siphon/vacuum pot (Hario, Yama).

Typical grind: medium.

Cold Brewing¶

Extraction occurs at low temperatures over extended periods, producing a distinctly different chemical profile from hot-brew methods. Characteristics: low acidity; smooth, sweet profile; often concentrated.

Methods: cold brew immersion (Toddy and similar), cold drip/Kyoto-style towers.

Typical grind: coarse.

Boiling/Decoction Brewing¶

Coffee is boiled directly in water, producing a strong, thick beverage with sediment. Characteristics: very strong; thick texture; sediment present.

Methods: Turkish coffee, Greek coffee, Arabic coffee (regional variations).

Typical grind: extra fine (near powder).

Hybrid and Assisted Methods¶

Combine elements of multiple extraction principles. Characteristics: adjustable flavour profile; high repeatability.

Methods: AeroPress (immersion followed by pressure), Clever Dripper (immersion then gravity drainage), pulsed pour-over hybrids.

Concentrate and Speciality Formats¶

Coffee brewed for dilution, cold service, or as a base for other preparations.

Methods: cold brew concentrate, nitro cold brew, Japanese iced coffee (brewed hot directly onto ice), espresso as a base for diluted drinks (Americano, long black).

Automated and Commercial Brewing¶

Designed for volume, consistency, or convenience at scale.

Methods: super-automatic machines, bean-to-cup machines, pod and capsule systems, commercial batch brewers, urn and airpot systems.

Key Facts¶

All brewing methods share the same objective: dissolving soluble coffee compounds into water at a controlled rate
The primary extraction categories are immersion, percolation, pressure, vacuum, cold, boiling, and hybrid
Core variables across all methods: ../Maps of Content/Grind Size MOC, Brew Temperature, Brew Time, agitation, and pressure
Different devices prioritise different combinations of these variables, producing characteristic cup qualities
