How to Make French Press Coffee

Six steps, four minutes, and one mistake almost everyone makes at the end. This is the National Coffee Association's method, with the numbers, plus what to do when it still tastes wrong.

By Stephen V.Last updated How we choose

A French press is the most forgiving brewer most people own, which is exactly why so much French press coffee is bad. There is no technique to get wrong, so people assume there is nothing to get right, and they end up with a gritty, bitter cup and conclude that this is simply what a press makes.

It is not. The method below is the National Coffee Association’s, with their numbers, and it takes about four minutes. The only genuine skill involved is grinding coarsely enough — everything else is a matter of doing the steps in order and, crucially, not leaving the coffee sitting in the press afterwards.

What you need

  • A French press, and something to boil water in
  • Coffee ground coarse — ideally from a burr grinder, or bought coarse ground
  • A scale, which is optional and makes more difference than any other five dollars you can spend

That is the whole list. No paper filters, no kettle with a spout, nothing to reorder — which is a large part of why a press is such a good gift. Our best French presses covers the brewers themselves, from a $30 glass classic to insulated steel.

The method, step by step

1. Grind coarse

The National Coffee Association calls for a coarse grind, about the size of rock salt. Anything finer slips through the mesh and ends up as silt in the cup.

2. Weigh the coffee and water

The NCA's range is 1 gram of coffee to 10–16 grams of water. Start at 1:15 — about 55 g of coffee for 830 g of water in a large press — and move toward 1:10 if you want it stronger.

3. Heat the water to about 93°C

The NCA specifies 93 ± 3°C, which is just off the boil. If you have no thermometer, boil the kettle and wait about thirty seconds.

4. Pour, wait a minute, then stir

Add all the water, let it sit for about a minute, then stir the crust of grounds on the surface back into the brew.

5. Lid on, three more minutes

Put the lid on with the plunger up. Total contact time is roughly four minutes.

6. Plunge gently, then pour it all out

Push the plunger all the way down slowly. Serve immediately, or decant into another vessel — coffee left sitting on the grounds keeps extracting and turns bitter.

If you want a single sentence to remember: coarse grind, 1:15, just off the boil, four minutes with a stir at one, and get it out of the press immediately.

The mistake almost everyone makes

Leaving the coffee in the press. This is so common that most people have never tasted a properly made press coffee, and it is the single easiest thing to fix.

Plunging does not stop the brewing. It pushes the grounds to the bottom, where they remain in contact with the coffee, continuing to extract. The first cup is good, the second cup ten minutes later is noticeably harsher, and the last cup from a press left on the counter for half an hour is genuinely unpleasant. The NCA is explicit: serve immediately or transfer to another container to prevent over-brewing.

The practical fix is to decant. Pour the whole press into a mug and a thermal carafe, or into two mugs, the moment you have plunged. A press with an insulated body helps with heat but does not solve this — the problem is contact with the grounds, not temperature.

Why the grind matters more than anything else

A press separates coffee from grounds with a metal mesh, and a mesh only stops particles bigger than its holes. Grind too fine and three things happen at once: fine particles pass into the cup as silt, they carry on extracting after you pour, and the plunger becomes hard to push because the bed is too dense.

This is also why a blade grinder is a poor match for a press. A blade chops beans into a mixture of boulders and powder, and the powder is exactly what the mesh cannot hold back — burr vs blade grinder explains the difference. If you are buying pre-ground, look for a bag ground coarse for immersion rather than a standard drip grind, which is far too fine.

Troubleshooting

Bitter and harsh

Almost always over-extraction. In order: decant immediately after plunging, grind coarser, shorten the steep to four minutes flat, and check that your water is not boiling when it hits the coffee — the NCA’s target is 93 ± 3°C.

Weak and sour

Under-extraction, and usually not enough coffee. Move from 1:16 toward 1:12. If it is still thin, the grind may be far too coarse, or the beans may be old — the NCA gives roasted beans one to three weeks at room temperature and ground coffee one to two, and how to store coffee beans covers keeping them that fresh.

Silt in the bottom of every cup

Some sediment is inherent to the method and is part of the body a press gives. A lot of it means the grind is too fine, or the mesh is worn or not seated properly against the wall of the carafe. If you want a genuinely clean cup, the method is wrong for you rather than the technique — a paper filter is what removes fines, which is what an AeroPress or a pour-over does.

It tastes stale, or slightly rancid

Clean the press. The NCA recommends cleaning the entire press after each use, including disassembling and washing the filter, because coffee oils accumulate in the mesh and turn. This is the cause people never suspect and it makes every cup worse until it is dealt with.

Making it better still

Two upgrades genuinely change the cup. The first is grinding fresh: whole beans keep for one to three weeks against one to two for ground, and grinding to order means you can dial the coarseness rather than accepting whatever the bag came at — whole bean vs ground sets out the trade properly.

The second is choosing coffee that suits immersion. A press amplifies body and roast character because the mesh lets oils through, so medium and darker roasts generally land better than delicate light ones — best coffee for French press has our picks, and light vs dark roast explains what the label predicts.

Frequently asked questions

What is the coffee-to-water ratio for a French press?

The National Coffee Association gives a range of 1 gram of coffee to 10 to 16 grams of water. A 1:15 ratio is a good default — roughly 55 g of coffee to 830 g of water for a large press — and moving toward 1:10 makes it stronger. Weighing is far more reliable than scoops, because ground coffee varies in density.

How long should French press coffee steep?

About four minutes of total contact. The NCA method is to pour, wait roughly a minute, stir the crust of grounds back in, then put the lid on for about three more minutes before plunging.

What grind size do you need for a French press?

Coarse — the NCA compares it to rock salt. The mesh filter only holds back particles larger than its holes, so a finer grind passes straight through and leaves silt in the cup, and those fine particles keep extracting after you pour, which turns the coffee bitter.

Why does my French press coffee taste bitter?

Three usual causes, in order. You left the coffee sitting on the grounds after plunging — decant it immediately. You ground too fine, so fines went through the mesh and kept extracting. Or you steeped much longer than four minutes. Water that is too hot is a distant fourth; the NCA's target is 93 ± 3°C.

Should you stir French press coffee?

Yes, once. The NCA method has you pour all the water, wait about a minute, then stir the crust of floating grounds back into the brew before putting the lid on. That breaks up the dry pockets so the whole dose extracts evenly.

Do you need to clean a French press after every use?

The NCA says yes, including disassembling and washing the filter. Coffee oils build up in the mesh and go rancid, and a press that has not been properly cleaned makes every subsequent cup taste bitter regardless of technique. It takes about a minute.
