French Press (Cafetière)

How a French press works

A cafetière is an immersion brewer: the grounds sit in the brewing water rather than having fresh water continually pass through them. After steeping, the filter moves down through the liquid and holds most of the grounds beneath it. The pressing action separates the drink; it is not an instruction to squeeze the grounds firmly.

The filter helps explain the characteristic texture. A conventional metal screen produces a different drink from paper filtration, while some specialist presses accept an additional paper filter to absorb oils and change the result. ESPRO explicitly describes this difference for its compatible presses.

For buying purposes, distinguish the vessel from the recipe. You can change the coffee dose, water quantity and brewing routine without replacing the brewer. Start with the short method below, then adjust deliberately rather than changing everything together.

If you are still deciding between manual brewing and an appliance, the coffee machines guide is the broader starting point.

Sizes, materials and double-walled versions

Choose capacity around your actual mugs

Manufacturer cup counts are not interchangeable with your kitchen mugs. Bodum’s published Chambord range includes 350 ml, 500 ml, 1 litre and 1.5 litre versions, described respectively as three, four, eight and twelve cups. Hario’s Cafe Press U comes in 300 ml and 600 ml capacities.

Measure the amount you normally serve before choosing. For example, two assumed servings of 250 ml require 500 ml of finished coffee. That arithmetic does not establish that a nominally 500 ml press will supply both: check whether the stated capacity means vessel volume, brewing-water capacity or finished beverage.

Also check minimum batch size. ESPRO publishes minimum brewing quantities for the P7, so the largest model is not automatically the most flexible choice for someone who usually drinks alone.

Compare construction, not appearance alone

The useful criteria are visibility, insulation, breakage considerations and care instructions.

These are construction choices, not a tested performance ranking. Manufacturer examples include Bodum’s glass Chambord and steel Columbia, ESPRO’s insulated P7, and Hario’s double-glass and wood-trimmed presses.

Double-walled does not necessarily mean vacuum-insulated. Bodum describes the Columbia’s insulation as air between its steel walls. Look for an explicit manufacturer statement before treating a double-wall description as a vacuum-flask specification.

My buying preference would be glass for someone who values visibility and serves immediately, or insulated steel where avoiding a glass beaker matters more. That is a suitability judgement, not evidence that either makes better-tasting coffee.

Filter mesh: what to inspect

Look beyond the number of screens. Check that the filter fits the vessel properly, can be dismantled without awkward handling, and is available as a replacement for the exact model.

ESPRO uses two nested filter baskets and a silicone seal. The manufacturer claims finer filtration than a conventional press, but its “grit-free” wording should be treated as a manufacturer claim, not an independently verified result here. More elaborate filtration also means more surfaces to separate and wash.

Replacement compatibility deserves particular attention. A screen that looks approximately right is not sufficient evidence that it fits. Ask the seller to confirm the model reference before ordering a replacement.

Do not confuse a finer filter with permission to use espresso-fine grounds. Bodum warns that fine coffee can clog its filter, while ESPRO also identifies fine particles and residue as causes of difficult plunging. Follow the instructions supplied with your press.

Brands

Compare brands against the same criteria: useful capacity, construction, filter design, cleaning access and replacement support. The examples below use manufacturers’ published descriptions, checked in November 2026; they are not a league table based on first-hand testing.

Bodum

Bodum’s Chambord provides the familiar glass-beaker format, while the Columbia uses double-walled stainless steel. Its published catalogue offers several sizes, making these useful ranges to compare when deciding between visibility and insulation.

Bodum also lists separate Chambord beakers and filter components. That provides a replacement route, but confirm availability and compatibility with a UK seller rather than assuming an overseas parts listing guarantees local stock.

ESPRO

The P7 is an insulated steel press with the company’s double-filter system. It is worth considering if filtration is a priority, provided you are happy to dismantle the baskets and respect the specified minimum brewing quantity.

Its detailed filtration claims do not establish that everyone will prefer the resulting coffee. Treat texture as a preference to explore, not a universal measure of quality.

Hario

Hario’s Cafe Press U uses heatproof glass, a polypropylene holder and stainless-steel filtering components, with published capacities of 300 ml and 600 ml. It offers a straightforward glass option to assess alongside the other brands.

Check the exact product rather than relying on an old photograph or range name. Hario Europe marks the 600 ml Olive Wood press page as discontinued, illustrating why current availability needs checking model by model.

Advantages/Benefits & Disadvantages

Advantages

• A straightforward brewing process. Add coffee and water, steep, then separate the grounds with the plunger.
• Reusable filtration. Conventional presses do not require a fresh paper filter for each batch.
• A choice of serving sizes and construction. Glass and insulated steel versions let you prioritise different ownership needs.
• Potentially replaceable components. Some manufacturers list separate beakers and filter parts rather than requiring replacement of the whole brewer.

Disadvantages

• You manage the process. Weighing, heating water, timing and serving remain manual tasks.
• Filter cleaning is part of every batch. Nested screens or assemblies need separating, not merely swilling.
• Glass requires inspection and careful handling. Bodum instructs users not to use scratched, chipped or cracked beakers.
• Insulation claims need context. A manufacturer’s statement about keeping coffee hot is not a guarantee of a particular serving temperature in your kitchen.

My assessment: a cafetière suits someone who wants involvement without a complicated operating routine. I would not choose it for a workplace where the priority is unattended, repeated drinks preparation and nobody has responsibility for washing the filter.

A practical starting method

This is an ownership-level starting routine, not a substitute for the instructions supplied with your brewer. The SCAA’s French press guidance uses a four-minute brew at 93.5°C; the rounded temperature below and single-pour routine are practical adaptations, not a claim to reproduce that protocol exactly.

1. Check the press. Use a stable, heat-resistant surface and inspect a glass beaker for damage.
2. Preheat, then empty it. Warm the vessel with hot water before adding the brewing ingredients.
3. Weigh 30 g of suitably ground coffee. Follow your manufacturer’s grind guidance.
4. Add 500 g of water, approximately 500 ml, at about 94°C. This suggested starting dose is 60 g per litre, or roughly 1:16.7 coffee to water by weight.
5. Wet all the grounds gently. Use a utensil permitted by the manufacturer, then fit the lid with the plunger raised.
6. At four minutes, plunge slowly and serve. Never force a resistant plunger.

Use a vessel with sufficient working capacity and the required headroom. Bodum’s instructions specify at least 2.5 cm below the top, so do not fill to the rim simply to reach a recipe quantity.

The first two checks follow manufacturer guidance; the capacity and compatibility checks are practical buying precautions.

Cleaning, water and everyday ownership

Let the contents cool enough to handle safely, then collect the spent grounds before washing. Do not deliberately wash the batch of grounds down the sink: Thames Water includes coffee grounds among the materials that should be kept out of drains.

Separate the filter assembly as directed, wash the exposed surfaces, rinse thoroughly and dry before storage. Dishwasher permission belongs to the particular product and finish, not to cafetières as a category. Hario lists the Cafe Press U as dishwasher-safe, but that does not establish the care requirements of a different press with decorative components.

For water, start with your own supplier’s report rather than a supposed UK-wide hardness figure. Thames Water, for example, provides postcode-based water-quality information and identifies calcium and magnesium as the minerals responsible for hardness.

Keep the receipt and model reference. For UK consumer purchases, GOV.UK explains that statutory rights concerning faulty goods are not replaced by a manufacturer’s warranty or guarantee. An office purchase may require a different assessment, so do not assume consumer guidance applies to every business order.
