What is a French press?

A French press — also called a cafetière or plunger pot — is an upright glass or steel carafe in which coarsely ground coffee is steeped for about 4 minutes, then separated by pushing a mesh plunger down. As a full-immersion method, it produces a cup rich in oils and body, with a round aromatic profile and no paper-filter masking.

The plunger coffee pot has a disputed origin: an early 1852 patent was filed in Paris by Mayer and Delforge, and a metal-mesh version was patented by Italian Attilio Calimani in 1929. The modern universal design, however, belongs to Danish company Bodum, whose Chambord model has been sold since 1974. English speakers say 'French press', Dutch speakers use 'cafetière', Germans call it 'Pressstempelkanne'.

The method is total immersion: all grounds stay in contact with all the water for the whole brew. That is a fundamental departure from pourover (V60, Chemex), which uses continuous gravity percolation. Immersion levels out extraction — every particle sees an equivalent volume of water — which makes the method fairly forgiving of uneven grind, a real advantage for home brewers who do not own a high-end grinder.

The mesh filter — 0.3 to 0.5 mm openings — lets oils and fine particles ('fines') pass, unlike a paper filter that traps them. The result is a rounder, oilier mouthfeel but also a slightly cloudy cup with a thin residue at the bottom. For drinkers watching cholesterol, unfiltered brews contain diterpenes (cafestol, kahweol) that measurably raise LDL over time. Studies in the European Journal of Preventive Cardiology (Thelle, Strandhagen and others) quantify the effect at a few mg/dL.

In Belgium, the French press is the most common home coffee tool after the electric drip machine. It has a particular place in guest houses, Ardennes holiday homes and Walloon Brabant gîtes, where it delivers a quality cup without a complicated machine. Its simplicity and minimal maintenance (rinse, brush, occasional descaling) also make it a common office brewer.

The Device That Democratised Quality Coffee

The French press is one of the most elegant pieces of coffee brewing equipment ever designed, and its elegance lies not in complexity but in simplicity: a cylindrical glass or metal vessel, a lid with a plunger attached to a metal mesh filter, and nothing else. No paper filters, no electricity, no moving parts beyond the plunger — just coffee, hot water, time, and a pushing action. This simplicity is both the device's greatest advantage and the source of its reputation for inconsistency: the absence of paper filtration means oils and fine particles enter the cup, which produces the characteristic heavy body that French press lovers prize but which requires attention to grind coarseness and brew time to avoid the sediment and bitterness that these particles can contribute when extraction is not carefully managed.

The French press was patented in France in 1929 by Attilio Calimani and Giulio Moneta, though similar devices had existed in various forms since the mid-19th century. Despite its name and association with French café culture, it never became the dominant brewing method in France itself — the country's café tradition favoured espresso — and achieved its greatest global adoption through British and American home use markets in the second half of the 20th century. Today it remains one of the three most popular home brewing methods worldwide alongside drip filter machines and pod-based systems, prized for its simplicity, its durability (quality glass and stainless French presses last decades), and the full-bodied cup character that its metal mesh filtration preserves.

Practical Recommendations

Choose a French press based on your typical brewing volume: the 350ml model (about 1-2 cups) for solo brewing, the 1-litre model for two to four people. Bodum, Fellow, and Le Creuset all produce quality models across price ranges. Glass models are visually appealing and easy to monitor during brewing but fragile; stainless steel models are virtually indestructible and retain heat better. Avoid plastic French presses — they absorb coffee oils and deteriorate under repeated thermal cycling. Invest in a burr grinder for your French press — blade grinders produce inconsistent particle sizes that result in simultaneous over and under-extraction in the same brew, producing a muddled cup regardless of recipe precision. The grinder is always the limiting factor in French press quality, even before you consider water temperature or brew time.
