The French press, or cafetiere as it is often called in British households, is one of the most enduring pieces of coffee equipment ever made. Simple, inexpensive, requiring no filters, no electricity and minimal technique, it has sat on kitchen counters and in office break rooms for generations. And when used well, it produces a genuinely outstanding cup: rich, full bodied, chocolatey and deeply satisfying in a way that filters and pods simply cannot match. The problem is that most people are not using it well, and a poorly made French press is bitter, muddy and forgettable.
This guide will help you make the most of yours. Whether you have been using a French press for years or just bought one, the details here will make a noticeable difference to your daily cup. None of it is complicated. It just requires knowing what to do and, equally importantly, knowing what to avoid.
- Grind: Coarse (like coarse sea salt). This is the single most important variable — too fine means bitter, gritty coffee.
- Ratio: 60–65g of coffee per 1 litre of water (roughly 1:15 by weight).
- Water temperature: 93–95°C — boiled water rested for 30–60 seconds.
- Steep time: 4 minutes exactly. Pour all coffee out immediately after pressing — it keeps extracting and turns bitter fast.
- Pre-warm the press with hot water before brewing. Small detail, noticeable difference in a cold kitchen.
Why French Press Coffee Tastes Different
The French press is an immersion brewer. Coffee grounds steep in hot water for several minutes, then a metal mesh plunger is pressed down to separate the grounds from the liquid. The key difference from filter methods is that the metal mesh filter allows coffee oils and very fine particles to pass through into your cup. No paper filter absorbs them.
Those oils are significant. They carry a large proportion of coffee's aromatic compounds and contribute mouthfeel, body and what people often describe as richness or roundness. French press coffee has a heavier, almost velvety texture compared to the lighter, cleaner character of pour over or filter coffee. Whether you prefer that richness or the cleaner clarity of filter coffee is largely a matter of personal preference, but there is no question that for full bodied, warming, coats the palate coffee, French press is one of the best tools available.
The fine particles that make it through the metal mesh also contribute to what is sometimes called coffee "sludge" or sediment at the bottom of the cup. This is normal and not a flaw. The trick is to pour carefully and leave the last 10 to 15ml in the press when you reach the end of the cup.
Grind Size: The Most Critical Variable
If there is one thing that separates good French press coffee from bad, it is grind size. French press requires a coarse grind, considerably coarser than what you would use for pour over or AeroPress. The texture should be similar to coarse sea salt or coarse ground black pepper.
Why does this matter so much? The metal mesh filter of a French press has relatively large pores. Fine ground coffee passes straight through into your cup, making it gritty and causing over extraction that produces harsh, bitter flavours. Medium grind also tends to produce over extraction during the 4 minute steep. Coarse grind is the correct starting point.
If you are using pre ground supermarket coffee, check the label: many bags sold as "cafetiere" or "French press" grind are already at approximately the right coarseness. Coffee labelled for filter or espresso is the wrong grind. If you have a burr grinder, set it to its coarsest or second coarsest setting and you will be close to right.
The Recipe and Method
Here is a reliable, straightforward recipe for a standard 8 cup (1 litre) French press. Scale it up or down proportionally for different sizes.
What you need: 60 to 65 grams of coarsely ground coffee, 900ml of freshly boiled water cooled for 30 to 60 seconds (aiming for around 93 to 95 degrees Celsius), timer.
Step one: Pre warm the French press by filling it briefly with hot water from the tap, then discarding it. This helps maintain brewing temperature throughout the steep.
Step two: Add your ground coffee to the dry press. Set it on a scale and zero it. Start your timer. Pour all 900ml of hot water slowly and evenly over the grounds, ensuring everything is saturated. Give it a gentle stir to make sure no dry grounds are sitting at the top.
Step three: Place the lid on the press with the plunger pulled up, not pressing down. This keeps the heat in. Set your timer for 4 minutes.
Step four: When 4 minutes are up, press the plunger slowly and steadily. Gentle, consistent pressure is the goal. If the plunger meets significant resistance and is very hard to press, your grind may be too fine. If it falls almost without resistance, it may be too coarse. The sweet spot is a press that takes around 20 to 30 seconds with moderate pressure.
Step five: Pour immediately. Do not leave brewed coffee sitting in the French press after pressing: the grounds remain in contact with the liquid and continue extracting, making the coffee increasingly bitter over time. If you are not drinking all of it at once, pour the remainder into a separate insulated vessel.
Choosing the Right Coffee for French Press
French press works beautifully with a wide range of coffees but tends to be most impressive with medium to dark roasts that have inherent body and chocolate or caramel notes. The full bodied character of the brewing method complements those qualities and produces a deeply satisfying result.
Sumatran coffee, with its naturally earthy, heavy character, is wonderful in a French press. Colombian medium roast produces a caramel rich, smooth cup. Brazilian naturals and darker roasted Central Americans are also excellent choices. The method is less ideal for very light roast single origins where you want delicate floral or citrus notes to shine: those are better served by a paper filter method that preserves their clarity.
Whatever you choose, freshness matters. Old, stale coffee will not bloom properly (French press benefits from fresh beans too), will produce a flat, dull cup and will not improve no matter how carefully you brew it. Buy freshly roasted beans and grind just before brewing for the best results.
Troubleshooting Common Problems
Bitter coffee: Grind is too fine or steep time is too long. Go coarser and stick to 4 minutes.
Weak, flat coffee: Grind is too coarse, not enough coffee, or water not hot enough. Try a slightly finer grind or more coffee, and check your water temperature.
Very gritty cup: Grind is too fine. A lot of grounds are passing through the mesh. Coarsen your grind and pour slowly, stopping before you reach the very bottom of the press.
Coffee getting bitter as it sits: You have left the brewed coffee in contact with the grounds after pressing. Pour it all out immediately into cups or a separate container.
Plunger very hard to press: Grind is too fine, creating too much resistance. Coarsen slightly.
