The French press (or cafetière) is immersion brewing at its simplest. Because the metal mesh filter lets natural oils through, it produces a heavier, richer body than paper-filtered methods. There is no pour technique to master and no specialized equipment beyond a press and a scale — making it one of the most forgiving ways to brew genuinely great coffee at home.
What you need
- A French press (this recipe scales for a 1-liter / 34 oz press)
- 55 g of freshly ground coffee beans
- A burr grinder set to coarse (like raw cane sugar)
- 830 g of filtered water at 96°C / 205°F
- A digital scale and a timer
Step-by-step French press method
- 1Coarsely grind 55 g of coffee (aim for a texture like coarse sea salt — no fine dust) and add it to a dry, pre-warmed press.
- 2Start your timer and pour in all 830 g of hot water in one slow, steady pour, saturating every ground.
- 3At 1:00, break the crust that forms on the surface with a spoon, stir once, then scoop off any foam or floating grounds.
- 4Place the lid on with the plunger pulled fully up. Do not press yet — this traps heat and keeps grounds submerged.
- 5At 4:00, press the plunger down slowly and steadily to just below the waterline. It should take about 20 seconds of light pressure.
- 6Immediately pour or decant every drop into a carafe or mugs. Leaving coffee on the grounds keeps extracting and turns bitter fast.
Pro tip: Pre-warm your French press with a splash of hot water before adding grounds. It stabilizes brew temperature and helps the coffee hit the intended extraction.
Why grind size matters more than anything else
A coarse, even grind is the single most important variable in French press. Too fine and the mesh filter cannot catch the particles — you end up with a muddy, gritty cup that is also bitter because the small grounds over-extract. A truly coarse grind (coarser than most people expect) produces a clean, sweet cup with no silt at the bottom.
How to troubleshoot your cup
- Bitter and harsh: grind coarser, shorten steep by 30 seconds, or reduce the dose slightly.
- Weak and sour: grind finer (but not too fine), increase dose to 1:14, or make sure all grounds were saturated at the start.
- Gritty or muddy: your grind is too fine, or the plunger mesh needs cleaning.
- Flat and dull: check your coffee freshness — stale beans produce flat cups regardless of method.
"The French press is the most honest brewer. It shows you exactly what the coffee is. There is nowhere to hide a bad grind or a stale bean."
Frequently asked questions
What is the best French press coffee-to-water ratio?
A 1:15 ratio is the ideal starting point — about 55 g of coffee per 830 g of water in a 1-liter press. Use 1:14 for a bolder, stronger cup or 1:16 for something lighter. The SCA recommends 55–60 g per liter for most immersion methods.
How long should French press steep?
Four minutes is the classic steep time and works well for most coffees and grind sizes. Steeping longer extracts more — which can mean more depth or more bitterness depending on grind. Decant immediately after pressing; never let it sit.
Can I use pre-ground coffee in a French press?
Yes, but look for coffee labeled "coarse grind" or "French press grind." Standard pre-ground coffee is usually a medium grind designed for drip machines — it will over-extract and leave silt in your cup.
Why is my French press coffee bitter?
Bitterness in French press almost always comes from one of three things: grind too fine (most common), steep time too long, or water too hot. Start by going coarser on the grind.
