Plunger coffee — known elsewhere as French press or cafetière — is one of the simplest ways to brew a rich, full-bodied cup at home. No pods, no dialling in an espresso machine, just coarse grounds, hot water, and a few minutes of patience. This guide walks through the method step by step, the grind that makes or breaks it, and how to pick the right plunger for your kitchen.

1. What you'll need

Plunger coffee doesn't need much kit, which is part of the appeal. Before you start, have these ready:

☕ A plunger (French press)

Any size works — just match it to how many cups you're pouring. See our range of French press plungers below.

⚙️ Coarsely ground coffee

Freshly ground is best. A burr grinder gives a far more even coarse grind than a blade grinder.

🌡️ A kettle and timer

You want water just off the boil, and four minutes you can actually track — a phone timer is fine.

🥄 A stirring spoon

Wood or plastic, not metal, especially with glass-carafe presses.

Pair it all with a bag of fresh coffee beans — plunger brewing is forgiving, but stale beans still make flat coffee no matter how well you follow the steps.

2. Step-by-step: how to make plunger coffee

  1. Preheat the press and measure your coffeeRinse the plunger with hot water to warm the glass and stop it stealing heat from your brew. Tip the water out, then add your coarsely ground coffee — a good starting ratio is roughly 1 part coffee to 15 parts water (about 30g of coffee for 450ml).
  2. Add hot water, just off the boilWater straight off a rolling boil can scald the grounds and pull out bitterness. Let the kettle sit for 30 seconds after boiling, then pour evenly over the grounds so all of it gets saturated.
  3. Give it one gentle stirBreak up any dry clumps floating on top with a single stir. This helps the coffee extract evenly rather than in patches.
  4. Steep for around 4 minutesPut the lid on with the plunger pulled all the way up, and leave it alone. Four minutes is a solid starting point — shorter for a lighter cup, a little longer if you like it stronger.
  5. Plunge slowly and steadilyPress straight down with even, gentle pressure. If it's hard to push, the grind is probably too fine — don't force it.
  6. Pour immediatelyThis is the step most people skip. Coffee left sitting on the grounds keeps extracting and turns bitter within minutes — decant the whole pot into a serving jug or straight into cups as soon as you've plunged.
Tip: If you're making enough for a crowd, decant into a thermal carafe rather than leaving coffee in the press "to keep warm" — it'll keep brewing and turn bitter well before it goes cold.

3. Getting the grind right

Grind size is the single biggest factor in how your plunger coffee turns out. Aim for something close to sea salt or coarse breadcrumbs — fine enough to extract properly in four minutes, coarse enough that it doesn't slip through the mesh filter or turn bitter.

Too fine

Produces a muddy, sediment-heavy cup and can make the plunger difficult to press. Also more prone to bitterness from over-extraction.

Too coarse

Water passes through too quickly, giving a thin, weak, under-extracted cup.

A quality home coffee grinder makes this far easier to get consistent, since a burr grinder produces an even particle size instead of the mix of dust and chunks you get from blades.

4. Common mistakes (and how to avoid them)

Using boiling water

Straight-off-the-boil water scalds the grounds. Let it sit 30 seconds first.

Grinding too fine

Espresso or drip grind will make a gritty, over-extracted cup in a plunger. Stick to coarse.

Steeping too long

Past about 4–5 minutes, extraction tips from balanced into bitter and astringent.

Not decanting straight away

Coffee left sitting on the grounds after plunging keeps extracting — pour it all out immediately.

6. Frequently asked questions

What's the best grind size for plunger coffee?

Coarse — roughly the texture of sea salt or coarse breadcrumbs. A grind that's too fine will slip past the mesh filter and turn the cup bitter and gritty; too coarse and the coffee will taste thin.

How long should plunger coffee steep?

Around 4 minutes is a solid starting point. Steep a little less for a lighter cup, or a little longer if you prefer it stronger — but beyond 4–5 minutes, most coffee starts tasting bitter and over-extracted.

Why does my plunger coffee taste bitter or gritty?

Usually one of three things: the grind is too fine, the water was boiling rather than just off the boil, or the coffee sat in the press too long after plunging instead of being poured out straight away.

Can I use pre-ground coffee in a plunger?

Yes, as long as it's ground coarse specifically for French press or plunger brewing — pre-ground coffee labelled for drip machines or espresso will be too fine and won't extract well.
