A French press is one of the easiest ways to make a full, rich cup at home. There's no paper filter, no power cord and no special technique: you steep coarse coffee in hot water, wait a few minutes, then push a mesh filter down and pour. Because nothing soaks up the coffee's natural oils, the cup comes out heavier and rounder than drip coffee.
How a French press works
It has three parts: a beaker (usually glass or stainless steel), a lid with a plunger rod, and a mesh filter on the end of that rod. The coffee and water sit together the whole time, which is called immersion brewing. That makes it forgiving: your pouring skills don't matter, and the time and the grind do almost all the work.
When you press, the mesh pushes the grounds to the bottom and holds them there while you pour. A little fine sediment always gets through, which is part of the French press character. The steps below keep it to a minimum.
What you need
- A French press. Glass lets you watch the brew; double-walled steel keeps it hot longer and won't crack.
- Coarse ground coffee. If you buy pre-ground, ask for a French press grind.
- A kettle and a spoon or chopstick for stirring (wood or plastic is kinder to glass).
- A kitchen scale and a timer (optional) for the same good cup every day.
French press coffee, 4-cup press
Hot · 6 min · 2 mugsYou need
- 32 g coarse ground coffee (about 6 level tablespoons)
- 16 oz (473 ml) water, just off the boil
- A 4-cup (17 oz) French press
Make it
- Warm the press with hot water and tip it out.
- Add the coffee and pour in about a third of the water.
- After 30 seconds, add the rest of the water and stir gently.
- Put the lid on with the plunger up and steep 4 minutes.
- Press slowly, then pour every drop into mugs or a carafe.
How to use a French press, step by step
- Heat the water Bring water to a boil, then let it rest for about 30 seconds so it lands around 93 to 96°C (200 to 205°F). Very dark roasts taste smoother a few degrees cooler.
- Warm the press Swirl a little hot water in the beaker and tip it out. A warm press holds its temperature through the steep, especially in a cold kitchen.
- Add coffee and bloom Add the coarse coffee, then pour in about a third of the water so every ground is wet. Wait 30 seconds while it bubbles. Fresh coffee releases gas here, and letting it escape helps the rest of the water reach the grounds evenly.
- Fill and stir Pour in the rest of the water and give it a few gentle stirs to sink the floating grounds. Set the lid on with the plunger pulled all the way up.
- Steep for 4 minutes Leave it alone. Four minutes is the starting point; you'll adjust from there once you taste it.
- Press and pour Push the plunger down slowly and steadily, taking about 15 to 20 seconds. If it fights back, ease up and let it settle. Then pour all of the coffee straight away, leaving the last thick spoonful in the beaker.
For a cleaner cup, skim the foam and floating bits off the top with two spoons before you press, then wait another minute or two for the fine particles to sink. It takes a little longer, and it's the closest a French press gets to a filtered cup.
French press sizes and how much coffee to use
French press "cups" are small, about 4 oz each, so a 4-cup press makes roughly two mugs. Fill the water to just below the top band so there's room for the lid and plunger. These amounts use a 1:15 ratio, a good middle-strength starting point:
| Press size | Water | Coffee | Tablespoons |
|---|---|---|---|
| Single mug | 8 oz (237 ml) | 16 g | about 3 |
| 3-cup (12 oz) | 12 oz (355 ml) | 24 g | about 5 |
| 4-cup (17 oz) | 16 oz (473 ml) | 32 g | about 6 |
| 8-cup (34 oz) | 32 oz (946 ml) | 63 g | about 12½ |
Tablespoon amounts are rough, because a spoon of coarse coffee weighs less than a spoon of fine. If you like it stronger, try 1:13 or 1:14; for milder, try 1:16 or 1:17. The coffee ratio calculator does the math for any amount of water.
The right grind
Go coarse, about like coarse sea salt or breadcrumbs. Coarse grounds are easy for the mesh to hold back, which keeps the cup clean and the plunger smooth. If your coffee is muddy and the plunger is hard to push, the grind is too fine. If the coffee tastes thin and sour and the plunger drops with no resistance, it's a bit too coarse. Our grind size chart shows what each size looks like.
A burr grinder gives the most even coarse grind. Blade grinders make a mix of dust and chunks, so if that's what you have, grind in short pulses and shake the grinder between them.
How to get less sludge in your cup
- Grind coarser and, if you can, use a burr grinder so there's less dust.
- Press gently. Ramming the plunger down churns up the fine particles you're trying to hold back.
- Let it settle for a minute after pressing before you pour.
- Pour slowly and stop before the last bit. The thick layer at the bottom is where the sediment ends up.
- Check the mesh. A bent or worn filter lets more through. Replacement screens are cheap and easy to swap.
More than hot coffee
- Cold brew: stir coarse coffee with cold water, cover and steep in the fridge overnight, then press. Our cold brew ratio guide has the amounts.
- Frothed milk: warm milk in the clean press, pump the plunger up and down for 20 to 30 seconds and you have foam for a latte. See how to make a latte without an espresso machine.
- Cold foam: the same trick with cold milk tops iced drinks. The cold foam recipe covers flavors.
- Tea: loose-leaf tea works well too. Rinse the press well afterwards so the flavors don't mix.
Troubleshooting
| Problem | Likely cause | Try |
|---|---|---|
| Bitter or harsh | Steeped too long, grind too fine, or left on the grounds | Steep 3–4 minutes, grind coarser, pour it all out after pressing |
| Weak or sour | Grind too coarse, water not hot enough, steep too short | Grind a little finer, use just-off-boil water, steep 5 minutes |
| Muddy or gritty | Too many fine particles | Coarser grind, press gently, skim and let it settle, leave the last bit |
| Plunger is hard to push | Grind too fine | Ease up, lift the plunger slightly, then press slowly; grind coarser next time |
| Plunger drops too easily | Grind too coarse or a worn filter | Grind a step finer, check the mesh for gaps |
| Coffee goes cold fast | Cold beaker or cold kitchen | Warm the press first, use a steel press or a cozy |
Hold the handle, not the beaker, and keep one hand on the lid while pressing. Check glass beakers for chips or cracks before each use, and never press hard enough to tip the press.
Cleaning and care
Don't rinse the grounds down the sink: they can build up in pipes. Instead, add a little water, swirl and tip the grounds into a fine sieve over the trash or compost, or scoop them out with a spatula. Then rinse the beaker and plunger in warm soapy water.
Once a week, unscrew the filter assembly and wash the mesh, cross plate and spiral plate separately. Old coffee oils hide between the layers and make fresh coffee taste stale. Let everything dry fully before putting it back together. If your water is hard, a soak in warm water with a spoon of citric acid every month or so clears any white film; our descaling guide explains how.
How much caffeine is in French press coffee?
An 8 oz cup usually has about 80 to 135 mg of caffeine, depending on the beans, how much coffee you use and how long it steeps. That's in the same general range as a cup of drip coffee. See caffeine in French press coffee for more detail.
This is general information, not medical advice. Caffeine affects people differently. If you're pregnant, nursing, sensitive to caffeine or have a health condition, check with your doctor about what's right for you.
Want to find your perfect cup? Change one thing at a time (the ratio, the grind or the steep time) and note how it tastes. The coffee brew timer has a French press setting that walks you through the bloom, steep and press.
Questions people ask
How much coffee do I put in a French press?
Start with 1 g of coffee for every 15 g of water. For a 4-cup (17 oz) press that is about 32 g of coarse coffee, roughly 6 level tablespoons, with 16 oz (473 ml) of hot water. Use a little more for stronger coffee and a little less for milder.
How long should French press coffee steep?
About 4 minutes is the classic starting point. Go to 5 minutes if it tastes thin or sour, or back to 3 minutes if it tastes bitter. Then press and pour it all out so it stops brewing.
What grind is best for a French press?
Coarse, about like coarse sea salt or breadcrumbs. Fine coffee slips through the mesh, makes the cup muddy and makes the plunger hard to push.
Why is my French press coffee bitter?
Usually it steeped too long, the grind is too fine, or the coffee was left sitting on the grounds after pressing. Pour it all out right after you press, or move it to a carafe.
Can I make cold brew in a French press?
Yes. Stir coarse coffee with cold water at about 1:8 for concentrate, cover it and leave it in the fridge for 12 to 18 hours, then press slowly and pour it off. Dilute the concentrate with water or milk to taste.
