French Press Coffee: Ratio, Grind, Recipe and Cleaning Guide

To make French press coffee, add 30 g of coarse-ground coffee to the press, pour in 480 ml of water at 90–96 °C (a 1:16 ratio), stir, and steep for 4 minutes. Then press the plunger down slowly and pour straight away. The metal mesh filter lets coffee oils through, so you get a rich, full-bodied cup.

What is a French press?

A French press (also called a cafetière or coffee plunger) is a glass or stainless-steel jug with a lid and a plunger. The plunger has a fine metal mesh filter at the bottom. You steep ground coffee in hot water, then push the plunger down to trap the grounds at the bottom and pour the coffee off the top.

This is called immersion brewing: the coffee sits in the water for the whole brew instead of water dripping through it, as in a drip machine. It is forgiving and needs no paper filters or electricity, which makes it one of the easiest ways to brew good coffee at home.

How to use a French press, step by step

This recipe makes about 2 cups in a 500 ml press. You need 30 g of coarse-ground coffee, 480 ml of water, a kettle, a spoon and a timer.

1. Heat the water. Bring it to a boil, then let it rest for about 30 seconds so it settles to 90–96 °C, the range the Specialty Coffee Association (SCA) recommends for brewing.
2. Preheat the press. Swirl a little hot water in the carafe, then discard it.
3. Add the coffee. Put 30 g of coarse-ground coffee in the press and shake it gently so the bed is level.
4. Bloom. Start your timer and pour in about 60 ml of water (twice the weight of the coffee), wetting all the grounds. Wait 30 seconds while fresh coffee bubbles and releases gas.
5. Add the rest of the water. Pour in the remaining water up to 480 ml and give it a gentle stir so there are no dry clumps.
6. Cover and steep. Put the lid on with the plunger pulled all the way up. Leave it until the timer reaches 4 minutes.
7. Press slowly. Push the plunger down with steady, gentle pressure over about 15–20 seconds. If it is very hard to push, your grind is too fine.
8. Pour right away. Serve all the coffee or decant it into a carafe or thermos. Coffee left sitting on the grounds keeps extracting and turns bitter.

For less sediment, try our French pull method, which lets the grounds settle instead of pressing.

French press coffee ratio for 1, 2 and 4 cups

The best starting ratio for French press is 1:16, meaning 1 g of coffee for every 16 ml of water. Stumptown Coffee’s French press guide uses a similar ratio (56 g of coffee to 850 g of water, about 1:15), while the SCA’s general brewing guideline of about 55 g per litre works out near 1:18. Use a slightly smaller ratio (1:15) for a stronger cup and a larger one (1:17) for a lighter cup.

Water amounts leave room for the grounds and plunger. Tablespoons assume about 7 g per level spoon; a scale is more accurate. For other brewers and batch sizes, see our coffee-to-water ratio chart.

What grind to use

Use a coarse grind, about the size of coarse sea salt or breadcrumbs, for two reasons:

• The filter. The metal mesh only catches larger particles. Fine grounds slip through and make the cup gritty and muddy.
• The steep time. Over 4 minutes, a fine grind over-extracts and tastes bitter, and it clogs the mesh so the plunger is hard to push.

A burr grinder gives the most even grind; blade grinders make chunks and dust, which means more sediment. No grinder? Order with YES (COARSE GRIND), our setting for French press and cold brew.

Is French press coffee stronger?

French press coffee usually tastes stronger, but it does not automatically have more caffeine. It helps to separate the two meanings of “strong”:

• Body and flavour. A paper filter traps coffee oils and very fine particles; the metal mesh lets them through, so the cup feels heavier and richer. Many people read this body as “strong”.
• Caffeine. How much caffeine is in your cup depends mostly on how much coffee you use, the size of the cup and the type of bean. At the same ratio, a French press and a drip brewer give broadly similar results. Use more coffee and you get more caffeine, whatever the brewer.

The bean matters more than the brewer. Robusta has roughly twice the caffeine of Arabica (see our Robusta guide). Kapeng barako (Liberica) tastes very bold and smoky, but its caffeine is similar to Arabica, not higher. So if you want more caffeine from your press, choose Robusta; if you want a bolder taste, barako and dark roasts deliver it.

One more difference: without a paper filter, French press coffee keeps natural oils such as cafestol, which studies link to higher cholesterol when unfiltered coffee is drunk regularly. If you are watching your cholesterol, paper-filtered coffee or drip bags are a sensible everyday choice.

Best beans and grind for French press

The French press brings out body, sweetness and chocolatey, nutty or caramel notes, so medium and dark roasts are the classic choice. Here is how our coffees compare in a press:

When you order, choose YES (COARSE GRIND) for French press, or NO for whole beans if you have a grinder. Whole beans stay fresh longer, because ground coffee loses aroma quickly once the bag is open. Not sure? Take our Coffee Match Quiz, request a free sample, or read how to choose coffee beans.

Troubleshooting: bitter, sour, muddy or hard to press

How to clean a French press

Old coffee oils and fine grounds collect in the mesh filter, go stale and make the next brew taste flat or bitter. A damp, dirty press can also smell or grow mould.

After every brew

1. Empty the grounds into the bin or compost, not the sink, where they can clog drains. Loosen them with a splash of water and scoop them out with a spoon or spatula.
2. Rinse the carafe and plunger with warm water before the grounds dry and stick.
3. Wash with mild dish soap and a soft sponge or brush. Pay attention to the spout and rim, where residue collects.
4. Dry fully before putting the press away.

Weekly deep clean

1. Take the plunger apart. Unscrew the rod and separate the mesh filter, spiral plate and cross plate.
2. Scrub each layer of the mesh with warm soapy water and a soft brush to remove trapped grounds and oil.
3. Soak if needed. For stubborn oil or stains, soak the metal parts and carafe in warm water with a little baking soda, or a mix of water and white vinegar, then rinse thoroughly.
4. Dry and reassemble with the mesh sitting flat so it seals against the glass.

Avoid steel wool and bleach. Check the maker’s instructions before using a dishwasher; hand washing is gentler on the mesh and seals.

Frequently asked questions

What is the best coffee to water ratio for French press?

Start with 1:16, which is 30 g of coarse-ground coffee to 480 ml of water for about 2 cups. Use 1:15 for a stronger cup or 1:17 for a lighter one.

How long should French press coffee steep?

Steep for 4 minutes, then press slowly and pour right away. If the coffee tastes weak or sour, give it a little longer or grind slightly finer. If it tastes bitter, grind coarser.

Is French press coffee stronger than drip coffee?

It usually tastes stronger because the metal filter lets coffee oils and fine particles into the cup, giving it more body. Caffeine depends mainly on how much coffee you use and the type of bean, so at the same ratio the caffeine is broadly similar. Robusta beans have about twice the caffeine of Arabica.

What grind should I use for French press?

Use a coarse grind, about the size of coarse sea salt or breadcrumbs. Fine grounds pass through the mesh, make the coffee muddy and bitter, and make the plunger hard to push. At Caffeine Brothers, choose YES (COARSE GRIND) when you order.

What is the best coffee for French press?

Medium and dark roasts are the classic choice because the French press brings out body and sweetness. Kapeng Barako, Robusta and CB’s Finest Signature Blend make a bold cup, while Benguet Arabica gives a lighter, smoother one.

How do you clean a French press?

Scoop the grounds into the bin or compost instead of the sink, then wash the carafe and plunger with warm soapy water after every brew. Once a week, unscrew the plunger and scrub each layer of the mesh filter, soaking it in baking soda or vinegar solution if oils have built up.
