A French press brews coffee by steeping grounds in hot water, then pressing them to the bottom with a metal filter

A French press (also called a plunger pot or cafetière) works differently from drip machines. Instead of water running through grounds, you mix grounds and hot water together in a glass or metal pot, let them sit for a few minutes, then push a metal mesh filter down to trap the grounds at the bottom. The result is a fuller-bodied cup because the mesh lets more of the coffee's natural oils through than paper filters do.

The whole process takes about 4 minutes from start to finish. You do not need electricity, special pods, or filters to buy. If you have a French press at home and hot water, you can make coffee right now.

Key Takeaways

  • Heat water to between 195 and 205 degrees Fahrenheit (just off boiling), and let it cool for 30 seconds after boiling if you do not have a thermometer.
  • Use a coarse grind — the same texture as breadcrumbs — because fine grounds slip through the mesh filter and end up in your cup.
  • The standard ratio is 1 part coffee to 15 parts water by weight, or roughly 1 tablespoon of grounds per 4 ounces of water if you are measuring by volume.
  • Steep for 4 minutes total: add water, wait 1 minute, stir, wait 3 more minutes, then press slowly over 30 seconds.
  • Pour when ready after pressing, because grounds continue to extract and will make the coffee bitter if left sitting.

Grind your coffee coarse, just before brewing

The grind size matters more than most people think. A coarse grind looks like breadcrumbs or sea salt — each piece is visible and separate. If your grinder has settings, aim for the second-coarsest or third-coarsest option. Grind only what you need right before you brew, because ground coffee loses flavor within 15 minutes of grinding.

Fine or medium grinds will slip through the mesh filter and end up as sediment in your cup, making it gritty. If your grinder only produces fine grounds, you can still use it — just accept that you will have some sediment at the bottom. Whole beans stay fresh for weeks; ground coffee stays fresh for days.

Heat water to the right temperature without a thermometer

Water that is too hot burns the coffee and tastes bitter. Water that is too cool under-extracts and tastes weak. The target is between 195 and 205 degrees Fahrenheit.

If you have a thermometer, use it. If you do not, boil water in a kettle, then wait 30 seconds before pouring. That 30-second pause cools the water just enough. Do not wait longer than a minute, or the water will cool too much and the coffee will taste thin.

Measure grounds and water by the 1-to-15 ratio

The standard ratio is 1 gram of coffee to 15 grams of water. If you have a kitchen scale, this is the easiest method: weigh your grounds, multiply by 15, and that is how much water to add.

If you are measuring by volume instead, use roughly 1 tablespoon of coarse grounds per 4 fluid ounces of water. A standard mug is 8 ounces, so 2 tablespoons of grounds and 8 ounces of water makes one mug. A French press marked for 3 cups usually holds about 12 ounces, so use 3 tablespoons of grounds and 12 ounces of water. You can adjust this ratio up or down depending on how strong you like your coffee — more grounds makes it stronger, more water makes it weaker.

Brew for exactly 4 minutes with a stir at the 1-minute mark

Pour a small amount of hot water into the empty French press first, swirl it around for 5 seconds, and dump it out. This warms the pot so the water temperature does not drop when you add the grounds. Add your coarse grounds to the warm pot.

Pour just enough hot water to wet all the grounds — about twice the volume of the grounds themselves. Wait 1 minute. This first minute is called the "bloom" and lets the grounds release gas so they absorb water evenly. After 1 minute, stir the grounds gently with a spoon, breaking up any clumps on the surface.

Pour the rest of the hot water slowly until the pot is full. Place the lid on top with the plunger pulled all the way up (do not press yet). Set a timer for 3 more minutes. At the 4-minute mark total, press the plunger down slowly and steadily over about 30 seconds. Do not rush — a slow press gives the mesh time to trap the grounds.

Pour when ready to stop the brewing

Once you press the plunger to the bottom, the grounds are still in contact with the water and the coffee is still extracting. If you leave it sitting, it will taste over-brewed and bitter. Pour all the coffee into your cup or a separate container within 30 seconds of finishing the press.

If you are making coffee for multiple people and cannot pour it all at once, pour what you can into cups right away, then pour the rest into a separate container or carafe. This stops the extraction and keeps the remaining coffee from getting too strong.

Common mistakes and how to fix them

Gritty coffee: Your grind is too fine. Ask the person at the coffee shop for a coarse grind next time, or adjust your grinder to a coarser setting. You can also pour your coffee through a fine mesh strainer into your cup to catch the sediment, though this removes some of the body you are trying to get from a French press.

Weak or thin coffee: You used too much water, too little grounds, or did not steep long enough. Try using 1 tablespoon of grounds per 3 ounces of water instead of 4, or add 30 seconds to your steep time. Water that is too cool also makes weak coffee — make sure you are waiting only 30 seconds after boiling before pouring.

Bitter or burnt taste: Your water was too hot, or you left the grounds sitting in the water too long after pressing. Boil the water and wait a full 30 seconds before using it. Pour when ready after pressing instead of letting it sit.

Coffee cools too fast: Warm the pot by rinsing it with hot water before you add grounds. You can also preheat your cup by filling it with hot water while the coffee brews, then dumping it out just before pouring.

Frequently Asked Questions

Can I use a French press with pre-ground coffee from a bag?

Yes, but check the label to see what grind it is. If it says "drip" or "all-purpose," it is probably too fine and will create sediment. If it says "French press" or "coarse," use it as-is. Pre-ground coffee loses flavor faster than whole beans, so it will taste weaker if the bag has been open for more than a week.

What if I do not have a scale or measuring spoons?

Use your fingers: a pinch of grounds is roughly 1 teaspoon. For water, fill your cup or mug and use that as your measure. The 1-to-15 ratio is a guideline, not a law — if your first pot tastes too weak, add more grounds next time; if it tastes too strong, add more water.

Can I make cold brew in a French press?

Yes. Use the same coarse grind and 1-to-15 ratio, but use cold water instead of hot. Stir once, cover, and let it sit at room temperature for 12 to 24 hours. Press and pour the same way. Cold brew tastes smoother and less bitter than hot-brewed coffee.

Why does my French press coffee taste different every time?

Water temperature and steep time are the biggest variables. If you are not using a thermometer, the 30-second wait after boiling can vary depending on your kettle and the room temperature. Try timing your steep with a phone timer instead of guessing, and use a thermometer if you have one. Coffee beans also taste different depending on how fresh they are and where they came from.

Is it safe to leave the plunger down while the coffee brews?

No. Pushing the plunger down before 4 minutes traps the grounds in the water and they over-extract, making the coffee bitter. Keep the plunger pulled all the way up during the steep, then press it down only at the end.
