french press is the first "real" coffee maker most people buy, and also the one most people get wrong. the good news: it's not you, it's the method. the classic "steep 4 minutes and slam the plunger" move is exactly how you get a gritty, bitter cup. here's the version that actually works.
quick history, because it's fun: the first piston-style coffee filter was patented in paris in 1852, and the design we know today - the mesh screen with a spring sealing it to the glass - was patented by two milanese designers, attilio calimani and giulio moneta, in 1929. so the french press is... italian. moving on.
what you need
- a french press. we sell a very cute one.
- coffee, ground coarse - like sea salt or breadcrumbs. if you grind at home, a burr grinder makes a huge difference here. our pick.
- a kettle
- a scale if you have one, a spoon if you don't
- 10-ish minutes of patience
the ratio
the specialty coffee association's golden cup standard is 55 grams of coffee per liter of water (about 1:18) for drip brewing. immersion brewing like french press runs a little stronger, so we brew at 1:15 to 1:16.
in normal-person units: 30 grams of coffee to 500 grams (aka 500 ml) of water. that's roughly two heaping tablespoons per cup if you're not weighing. two big mugs' worth.
the method (the no-sludge way)
this is the james hoffmann method, and it fixes everything people hate about french press.
- boil your water. seriously, full boil is fine for french press.
- add 30g coarse coffee to the empty press. pour in 500g of water, making sure all the grounds get wet.
- put the lid on, plunger up. wait 4 minutes. don't stir, don't touch it.
- at 4 minutes, a crust of grounds has formed on top. stir it gently with a spoon - most of it will sink. scoop off the foam and the floaty bits left on the surface and toss them.
- now the hard part: do nothing for at least 5 more minutes. the tiny particles that make your cup muddy are sinking to the bottom right now. this wait is the whole trick. the coffee's also too hot to enjoy before this anyway.
- put the plunger in and lower it until it just touches the surface of the coffee. do not press it down. the plunger is a strainer, not a piston - pressing it stirs all the sediment you just waited 10 minutes to settle.
- pour slowly into your mug. leave the last bit in the press.
common mistakes
- grinding too fine. fine grounds slip through the mesh and over-extract. coarse is non-negotiable.
- plunging to the bottom. see above. strainer, not piston.
- letting the coffee sit in the press after brewing. it keeps extracting and goes bitter. pour it all out (or into a carafe) once it's done.
- giving up on it because "french press is always muddy." it isn't. you just hadn't met the 5-minute wait.
if your cup still tastes off after all this, the beans or the water are usually the culprit. we wrote about that.
faq
how long should french press steep?
4 minutes before you touch it, then another 5 to 8 minutes of hands-off settling. total contact time around 10 to 12 minutes - and no, it won't get bitter, because nothing is being agitated.
what grind for french press?
coarse - sea salt texture. finer grinds pass through the mesh filter and make sludge.
do you really not push the plunger down?
correct. press just to the surface and pour through it. plunging to the bottom re-mixes the sediment into your cup.
can i use pre-ground coffee?
you can, but most pre-ground is sized for drip machines - finer than ideal. expect a little silt, or ask your local cafe to grind coarse for you. our cafes will do it.
