How to Make Coffee with a Cafetière (French Press)

Comment préparer un café avec une French Press (cafetière à piston)

The French press is one of the simplest and most honest ways to make coffee. No paper filter, no complicated machine, just coffee, hot water and a French press. In a few minutes, it gives you a generous, rounded cup full of aroma. With its see-through design and its unhurried ritual, the French press invites you to take your time. A homely coffee, straightforward, bold when it needs to be, always sociable. Simple, effective and truly timeless.


 

What you need

  • A French press
  • 15-20 g of coffee beans, coarsely ground for a French press
  • 300 g of filtered water, just off the boil
  • A spoon or stick for stirring
  • Precision scales
  • A timer

What we used for this guide

  • Our seasonal coffee from Kenya, Kamwangi AA
  • Timemore Chestnut C3S Pro hand grinder
  • Timemore Basic 2.0 scales
  • Timemore Fish Smart kettle

 

 

Tip: getting the ratio right

Whatever the size of your French press, a good rule of thumb is a coffee-to-water ratio of 1:15.

In other words, for every 1 g of coffee, add 15 g of water, which works out at roughly three and a half tablespoons of coffee per cup of water.

From there, feel free to experiment until you find the ratio that suits your taste best.

 

Method

Step 1: Grind the coffee

For 4 cups, use 15 to 20 g of coffee, depending on the size of your French press and how strong you like it. Grind the coffee coarsely, to a texture similar to coarse sea salt.

 

 

Step 2: Bloom

Start the timer and pour in roughly 60 ml (60 g) of water just off the boil, making sure all the grounds are wet (you can give it a gentle stir with a wooden spoon), then leave it for 30 seconds to bloom.

 

 

Step 3: Steep

Pour in the remaining 240 ml of water, then put the lid on without pressing the plunger, to keep in the heat and all the aromas. Leave to steep for another 3 minutes 30 seconds.

Step 4: Plunge

Gently press the plunger all the way down, then pour and enjoy.

 


What few people know about the French press

  • Its origins are an international comedy: although it's called a French press, France, Italy, Switzerland and even Denmark all lay claim to its invention! Two Frenchmen filed a first patent in 1852, the Italian Attilio Calimani filed another in 1929, and a Swiss man named Faliero Bondanini started producing it in France in the 1950s… in a clarinet factory! Yes, the French press was made in the same place as clarinets.

  • Its name is a bone of contention too: in France it's a "cafetière à piston", in the UK a "cafetière", elsewhere a "French press", a "coffee plunger" or even a "Bodum" (after the Danish brand that makes it).

  • The happy accident behind the first cup: legend has it that a Frenchman out on a walk wanted to make himself a coffee and forgot to add the coffee at the right moment. In desperation, he bought a piece of metal from an Italian to separate the grounds from the coffee, and so invented the plunger by accident. Proof that forgetfulness can lead to innovation.

FAQ

For a cafetière, go for a coarse grind, similar in texture to coarse salt.

If the grind is too fine, it will get through the filter and make your coffee cloudy and more bitter. If it's too coarse, you risk a weak, under-extracted cup.

Ideally, grind your coffee just before brewing to preserve the aromas and get a rounded, balanced, clean-tasting coffee.

A little sediment is normal with a cafetière (it's what gives the coffee its body), but if there's too much, your grind is too fine or your grinder is producing too many "fines" (coffee dust).

No. Even once the plunger is down, extraction carries on. If you leave the coffee in, it will turn bitter and over-extracted. Pour it all into a cup or a jug straight away.

Cleaning your cafetière is essential to stop rancid coffee oils building up, as they cause bitter or flat flavours.
After each use, take the plunger apart and rinse all the parts in lukewarm water, without washing-up liquid. Pay special attention to the metal filters, where oils tend to collect in the mesh.
Once a week, for a deeper clean, soak the filter and plunger in hot water with a little bicarbonate of soda or white vinegar, then rinse thoroughly in clean water.
Let everything dry fully before reassembling.

The result: a clean cafetière, clear aromas, and a coffee that keeps only the good stuff.

The cafetière and the Aeropress are both immersion brewing methods, but they give very different results:

  • French press: it uses full immersion and a metal filter. The result is a heavy, textured coffee, because the oils are preserved.

Aeropress: it usually uses paper filters and pressure to extract the coffee, giving a cleaner, lighter cup.
