How to Make French Press Coffee: An Easy Step-by-Step Guide

Is your French press sitting in the cupboard because the coffee always comes out weak, full of grit, or too bitter? It has a reputation as an “easy method,” but most recipes out there teach it wrong. Here’s the right step-by-step process, with the ratios and times that actually work.

Why the French press needs more coffee than other methods

The French press works by immersion: the grounds stay fully submerged, sitting in the water, instead of the water flowing through them continuously like in a pour-over (that continuous flow is called percolation). Immersion is naturally less efficient at pulling flavor out of the coffee, so it needs a more concentrated ratio to avoid turning out weak.

Because of that, forget paper-filter ratios (1 to 16 or 1 to 18) in the French press. They leave the drink thin and flat. The right range here is 1 to 14 to 1 to 15, meaning between 65 g and 70 g of coffee per liter of water.

The base recipe

• Coffee: 30 g
• Water: 450 ml (ratio of approximately 1 to 15)
• Grind: medium to medium-coarse, similar to what’s used for the V60 or a common paper filter
• Temperature: 90.5 °C to 94 °C for dark roasts; 94.4 °C to 96 °C for medium and light roasts
• Total steep time: 4 minutes, not counting decanting

Fine-tuning by roast: use 1 to 15 for dark roasts and 1 to 17 for light roasts, since lighter beans need more water to release all their flavor.

The myth of a “really coarse” grind

A lot of recipes out there tell you to use a huge grind, almost a whole bean. That’s a mistake. A grind that’s too coarse, combined with immersion (which is already less efficient), leaves the coffee underextracted: weak, lacking sweetness, and with a somewhat “dirty” taste.

The ideal grind is medium to medium-coarse, the same range used for paper drippers. If you’re using a blade grinder, which spins and chops the bean unevenly instead of cutting it uniformly, shake the appliance while grinding, like a cocktail shaker, to reduce the size difference between the pieces.

Step-by-step brewing process

1. Preheat the press with hot water, let it sit a few seconds, and discard it. This keeps the cold glass from stealing temperature from the water during the brew.
2. Add the 30 g of ground coffee to the bottom of the carafe.
3. Pour all the water at once, quickly and with a wide stream, using a kettle with a wide spout (no need for a gooseneck here, unlike the V60). The goal is to wet all the grounds at once.
4. Don’t stir. Let it steep for 4 minutes. During this time, a layer will form on top, the crust, made of grounds and the carbon dioxide the coffee releases. It acts as a natural lid, helping retain heat.
5. At the 4-minute mark, break the crust gently with a wooden or plastic spoon, so the grounds sink.
6. Skim off the foam left on the surface with two spoons, removing as many floating particles as possible.
7. Wait a few more minutes without pressing, to let the fine sediment settle by gravity.
8. Lower the plunger very slowly, with almost no pressure, just down to the surface of the liquid.
9. Serve right away, or better yet, decant all the coffee into a separate carafe.

Why you should never let the coffee “sit” in the press

This is the most common mistake, and the reason so many people find the French press bitter. If the coffee stays in contact with the grounds at the bottom, extraction keeps happening even after you pour the first cup. The second cup comes out stronger and more bitter than the first.

The fix is simple: decant the entire volume into a clean carafe as soon as the steep time is up. That way, extraction stops right there, and every cup comes out with the same flavor.

The other classic mistake: pressing too hard

Pushing the plunger forcefully all the way down makes the fine particles (those tiny bits of coffee, almost a powder) pass through the metal mesh and fall into the cup. That gritty sediment at the bottom of the glass is what makes so many people complain about French press “grit.”

Press very slowly, with almost no weight, or stop the plunger right at the surface of the liquid, letting it act as a gentle sieve instead of pushing everything down.

A more advanced method, for those who want to go further

If you’ve already mastered the basic recipe and want even more control over body and clarity, there’s a variation with an extended time:

1. Let it steep for 5 minutes initially.
2. Stir the water well to break down the crust and reactivate the extraction.
3. Cover and wait 3 more minutes (8 minutes total).
4. Lower the plunger very gently.
5. Wait 2 more minutes before serving, to let the sediment settle for good.

It’s more work, but it yields a cleaner coffee with an even more balanced body.

Precautions that save you a headache

• Use a wooden or plastic spoon, never metal. It can crack the press’s glass when scraping the bottom.
• Prefer filtered, soft water. Hard water or water with a strong chlorine taste changes the result.
• Use coffee roasted 1 to 3 weeks earlier, the window in which the bean has already released most of its gas and is more stable.

If you want an even cleaner coffee, without the oils and sediment that give the French press its signature body, there’s a trick: place a paper filter over the plunger’s metal mesh before pressing. It catches whatever would otherwise pass through the screen.

How to test it at home

1. Make the base recipe: 30 g of coffee, 450 ml of water, medium grind.
2. Taste and identify the problem: weak and cloudy, or strong and bitter?
3. Weak and cloudy coffee: the grind is too coarse. Adjust to medium.
4. Strong coffee, but with a lot of sediment: review how much force you used when pressing. Go slower.
5. Change one variable at a time and test again.

Quick tips

• Always decant the coffee as soon as the steep is done, even if you’re only having one cup.
• Use a burr grinder, which cuts the bean more evenly than a blade grinder.
• Preheat the press before using it, especially if it’s glass.
• Don’t confuse “full body” with “full of grit.” The first is a trait of the method; the second is a pressing mistake.

Frequently asked questions

Why does my French press coffee always come out weak?

You’re probably using a pour-over ratio. Increase the dose to the 1 to 14–1 to 15 range, much more concentrated than what the V60 or Chemex calls for.

Is it normal to have a bit of grit at the bottom of the cup?

A little is normal, since the filter is a metal mesh, not paper. A lot of grit, though, points to pressing too hard or grinding too fine.

Can I leave the finished coffee in the press to drink later?

It’s not recommended. The coffee stays in contact with the grounds and keeps extracting, growing more bitter over time. Decant it into a separate carafe as soon as the brew is done.

Your next cup in the French press

Increase the coffee dose, choose a medium grind, press slowly, and always decant. With these four adjustments, the French press stops being synonymous with weak or gritty coffee and becomes one of the fastest, tastiest methods in your routine.
