How to make french press coffee at home

Coarse grind, hot water, four minutes. Here's the whole method, and what to change when a cup comes out muddy, bitter, or weak.

A french press is the simplest way to brew a full-bodied cup. The grounds steep in hot water, then you push a metal mesh filter down to hold them at the bottom. Because the mesh lets the coffee's natural oils through, the cup tastes heavier and rounder than one made with a paper filter. It's hard to do badly, and a few small habits make it much better.

What you need

• A french press. A standard 34 fluid ounce (1 liter) press fits this recipe with room to spare.
• A kettle. Any kettle works.
• A kitchen scale that reads in grams (most can switch from ounces)
• Whole beans and, ideally, a burr grinder with a coarse setting
• A timer. Your phone is fine.
• A spoon for stirring

Weighing is still worth it here. Scoops vary a lot with grind size and bean density, and weight is what makes a good cup repeatable. Coffee is weighed in grams because an ounce is about 28 of them, so ounces are too coarse to hold a ratio. Ounce equivalents are in parentheses.

Step by step

1. Warm the press. Rinse the empty carafe with hot water and pour it out. A cold glass pulls the heat out of your brew.
2. Add the coffee. Put the ground coffee in the carafe, set it on the scale, and zero the scale.
3. Pour and start the timer. Pour in all 450 g (15 oz) of water, making sure every bit of coffee is wet. Set the lid on top with the plunger still up, which holds in the heat.
4. Steep for 4 minutes. Leave it alone. A crust of grounds will float on top.
5. Stir and press. At 4:00, give the crust a gentle stir, then press the plunger down slowly over about 20 to 30 seconds. Use steady pressure and don't force it.
6. Pour it all out right away. Coffee left sitting on the grounds keeps extracting and turns bitter. If you're not drinking it all, pour the rest into a mug, carafe, or thermos.

If it doesn't taste right

Change only one thing at a time, so you know what made the difference.

• Muddy or gritty: the grind is too fine, or your grinder makes a lot of dust. Grind coarser, let the cup sit for a minute before drinking, and leave the last sip behind.
• Bitter, harsh, or dry: the coffee is over-extracted. Grind coarser, shorten the steep to 3½ minutes, or pour it out sooner after pressing.
• Sour, thin, or salty: the coffee is under-extracted. Grind a little finer, use slightly hotter water, or steep for 4½ minutes.
• Weak but not sour: use more coffee. Try 35 g (1.2 oz) with the same 450 g of water.
• Hard to press down: the grind is too fine or there's too much coffee. Grind coarser, and don't push harder to make up for it.

Tips that make a bigger difference than gear

• Grind right before you brew. Ground coffee goes stale within minutes, not days. A burr grinder makes even pieces, while a blade grinder makes a mix of boulders and dust, and the dust ends up in your cup.
• Buy fresh beans. Beans taste best in the first few weeks after roasting. Look for a roast date on the bag, not just a best-by date.
• Don't rinse grounds down the sink. They clog drains. Scrape them into the trash or compost, then rinse the carafe.

This guide describes a widely used starting method, not a single correct way. Some brewers steep longer and skim the foam off the top before pressing, and others use a slightly different ratio. Beans, grinders, and water all vary, so treat the numbers as a starting point and adjust to your taste.
