How do you make French press coffee?
Quick answer
Use 20 g coarse-ground coffee per 300 ml water (about 1:15), water near 93 °C (200 °F), steep 4 minutes after a quick stir, then press slowly. Pour immediately — leaving coffee on the grounds makes it bitter.
What you need
- French press — common sizes are 350 ml (1–2 cups), 500 ml (2–3 cups), and 1 L (4+ cups). Any size works; just keep your ratio the same.
- Coarsely ground coffee — pre-ground labeled "French press" works, but a burr grinder gives you more control.
- Kettle — a gooseneck is nice but not required. You just need a way to pour without flooding the grounds all at once.
- Scale — optional but worth it. Eyeballing coffee leads to inconsistent cups.
- Timer — the French press timer has the phases preset.
Grind size is critical
Coarse grind means roughly the size and texture of sea salt — chunky, not powdery. Hold a pinch up to the light; individual particles should be visible.
Too fine: grounds slip through the mesh filter, the water struggles to flow through, and you end up with a muddy, over-extracted cup that tastes bitter and harsh. The plunger will also be hard to push down.
Too coarse: water flows past the grounds without picking up enough flavor. The cup tastes thin and sour (under-extracted).
If you're dialing in a new bag of coffee, start at coarse and nudge finer if the cup tastes weak. One step at a time — grind size changes have a big effect.
Step by step
- Heat water to boil, then rest 30 seconds (~93 °C / 200 °F).
- Add coffee — coarse grind, 20 g for 300 ml water.
- Bloom — pour just enough water to saturate all the grounds (roughly twice the weight of coffee, so ~40 ml). Stir gently to make sure every ground is wet, then wait 30 seconds. You may see the grounds puff up and release bubbles — that's CO₂ escaping from freshly roasted coffee. Letting it off-gas first means the water extracts flavor more evenly during the steep. Start your timer now.
- Add the rest of the water — pour slowly in a spiral to distribute evenly. Place the lid on with the plunger pulled up.
- Steep 4 minutes — don't press yet. Leave it alone.
- Press and pour — apply slow, steady downward pressure. If it feels like you're forcing it, stop — your grind is too fine. Once pressed, pour everything out immediately.
Why you should pour immediately
Once you press the plunger, the coffee is still in contact with the grounds. Extraction doesn't stop at the four-minute mark — it keeps going as long as hot liquid sits on top of compressed grounds. The oils and fine sediment that make French press taste rich will tip into bitter and muddy if you let it sit for another five minutes. Pour into cups or a separate carafe right after pressing. If you're not drinking it immediately, move it to an insulated vessel — not back into the press.
Scaling the recipe
| Serving | Coffee | Water |
|---|---|---|
| 1 cup | 13 g | 200 ml |
| 2 cups | 20 g | 300 ml |
| 4 cups | 40 g | 600 ml |
| Full 1 L press | 67 g | 1000 ml |
All at the same 1:15 ratio. Use the ratio calculator to adjust for other press sizes.
Troubleshooting
Bitter cup — most common cause is over-extraction. Try shortening the steep to 3:30, or use slightly cooler water (90 °C instead of 93 °C). A grind that's too fine also extracts fast and runs bitter.
Muddy / gritty cup — grind is too fine, or you pressed too hard and forced sediment through the mesh. Go coarser and press more gently. Some sediment in French press is normal and harmless; a muddy slurry means the grind is off.
Weak / sour cup — under-extraction. Either your grind is too coarse, your water wasn't hot enough, or you didn't steep long enough. Try extending to 4:30 or nudging the grind finer.
Oily / heavy mouthfeel — this is a feature, not a bug. French press uses a metal mesh instead of a paper filter, so natural coffee oils pass through into the cup. That's what gives it body. If it feels too heavy, a medium coarser grind and shorter steep can dial it back.
Plunger hard to push — grind too fine. Do not force it. Pull the plunger back up, wait another minute, then try again. If it's still stiff, go coarser next time.
Common questions
Why is my French press muddy? Grind too fine or pressed too hard. Go coarser.
Why is it bitter? Steeped too long or water too hot. Try 3:30 and cooler water.
French press vs pour over? French press = fuller body; pour over = cleaner cup. See the comparison.
