Overview¶

The French press (also called cafetière, press pot, or plunger coffee) is a full-immersion brewing device consisting of a cylindrical glass or stainless steel vessel and a plunger fitted with a metal mesh filter. Coarsely ground coffee is steeped in hot water for several minutes, then the plunger is pressed down to separate the grounds from the liquid. As an immersion method, French press coffee retains oils and fine particles that paper filtration removes, producing a heavier body, richer mouthfeel, and more complex — if occasionally murkier — cup character than filter paper methods. It is one of the most popular manual brewing methods globally.

Brewing Parameters¶

Parameter	Target range	Notes
Brew ratio	1:12 – 1:17	1:15 common starting point
Grind size	Coarse	Finer grind causes excessive extraction and murky sediment
Water temperature	92–96°C	Off-boil; 93°C is a common reference
Steep time	3–5 minutes	Shorter: under-extraction; longer: over-extraction
Plunge technique	Slow, gentle	Aggressive plunging stirs up sediment

Brew Method¶

Pre-heat: Pour hot water into the carafe; discard; add ground coffee
Bloom (optional): Pour a small initial amount of water to wet the grounds; wait 30 seconds for degassing
Add all water: Pour to target volume; stir briefly to ensure full saturation
Steep: Put lid on with plunger raised; wait target time (3–5 minutes)
Plunge: Press plunger slowly and evenly to the bottom
Pour immediately: Continued immersion after plunging causes over-extraction; decant all coffee to a carafe or cups

Why Coarse Grind¶

A coarse grind is essential for French press for two reasons: 1. Extraction control: Long steep time with finer grind over-extracts — producing bitterness 2. Sediment management: Fine particles pass through the metal filter into the cup; coarser grinding reduces fine particle generation and keeps the cup cleaner

Cup Character¶

French press produces a distinctive cup: - Heavy body: Metal mesh retains oils and allows fine particles into the cup, producing full, rich mouthfeel - Less clarity: Some sediment and oils produce a less "clean" cup than paper filtration - Complexity: Oil retention adds flavour dimensions absent in paper-filtered coffee - Temperature retention: Thick glass or insulated steel carafe retains temperature during brewing

Key Facts¶

French press is a full-immersion brewing device using a metal mesh plunger; not paper-filtered
Standard parameters: 1:15 ratio, coarse grind, 93°C, 4 minutes steep time
Metal mesh allows oils and fine particles through — produces heavier body than paper filter methods
Decant immediately after plunging; leaving coffee in the press continues extraction and becomes bitter
Coarse grind is essential: fine grinding causes over-extraction and excessive sediment in the cup
