How to Brew Great Coffee with a French Press

If you’ve ever made coffee with a French Press and ended up with sludgy grounds or thin, bitter liquid, you’re not alone. Many assume the French Press is just about tossing in coffee and hot water—but getting a truly great cup requires a few essential tweaks to ratios, timing, and technique.

The simplest way to get a solid cup from a French Press is to use a 1:15 brew ratio (14g coffee to 225ml water), steep for around 4 minutes, and use a coarse grind—about the size of coarse sugar or fine gravel.

What Is a French Press and Why Use It?

A French Press, also known as a coffee plunger or press pot, is a straightforward, durable coffee maker made of a glass or metal carafe with a built-in metal mesh filter and plunger. It’s valued for being easy to use and producing a full-bodied cup due to its immersion-style brewing. Unlike pour-over methods, all the coffee grounds sit in hot water for the full brew, resulting in more oils and body—along with some sediment if not filtered well.

How to Make Coffee with a French Press (Step-by-Step)

Making coffee with a French Press involves five basic steps, but small changes in grind, time, temperature, and stirring can significantly affect your results.

• Step 1: Add hot water (ideally 85°C–95°C, or let boiled water rest 2–3 minutes) to the empty French Press. This preheats the vessel.
• Step 2: Add your freshly ground coffee—around 14g per 175ml (standard single serve), or 28g for 300ml. The original French Press design leaves room for settled grounds at the bottom.
• Step 3: Pour water over the grounds. For best results, aim for a 1:15 brew ratio (14g coffee to 225ml water). You can adjust strength to taste.
• Step 4: Stir the coffee gently with a spoon—or lightly press the plunger down and lift—to ensure even saturation. Let it steep for around 4 minutes. Adjust time for taste: shorter for lighter extractions, longer for stronger brews.
• Step 5: After steeping, press the plunger down slowly and steadily. Then pour the coffee immediately into your cup to avoid over-extraction from sitting on the grounds.

Key Variables That Change Your French Press Coffee

While the basic steps are simple, the following variables give you control over the final cup profile:

• Brew Ratio: Most French Presses have volume markers (e.g., 175ml or 300ml per ‘cup’). A common starting point is 14g coffee per 175ml water (1:15 ratio). Adjust to suit taste preferences—more coffee for stronger, less for milder.
• Grind Size: Use a coarse grind, similar to coarse sugar or small gravel. Too fine, and fine particles will pass through the metal filter, making the coffee gritty. For reference, FrontStreet Coffee suggests a grind akin to coarse sugar or about 3–4x the size of granulated white sugar—comparable to 3.5 on a Hario Mini Mill (or EK43s setting 10.5 / hand grinder 26).
• Water Temperature: Ideal range is 85°C–95°C. Avoid boiling water to prevent burnt or overly bitter notes. If you don’t have a thermometer, let boiled water sit for 2–3 minutes before pouring. Lower temperatures risk under-extraction and flat, sour flavours.
• Steeping Time: Most brewers get good results with 4 minutes. Shorter times yield lighter extraction; longer times can increase bitterness, especially with dark roasts.
• Stirring: Stir once after pouring water to ensure even saturation. Some brewers gently press the plunger and lift to mix. Consistent agitation helps with even extraction.

French Press Tips & Tricks

• Preheat your French Press and cup to keep your coffee hotter for longer.
• Avoid pressing the plunger too hard or too fast—it can over-extract and stir up fine particles.
• If you want to minimise coffee grounds in your cup, try placing a paper filter inside the press or pouring through an additional filter.
• Darker roasts tend to do better in a French Press—they complement the heavy body and reduce the perception of any bitterness or sediment.

Frequently Asked Questions

What is the best grind size for French Press coffee?

The ideal French Press grind size is coarse—about the size of coarse sugar or small gravel. It should resemble 3–4x the size of standard table sugar. Too fine a grind will allow coffee particles to pass through the metal filter, resulting in a gritty cup. For reference, FrontStreet Coffee recommends a setting similar to 3.5 on a Hario Mini Mill, or EK43s setting 10.5 / hand grinder 26.

What coffee-to-water ratio should I use in a French Press?

A standard and reliable brew ratio is 1:15—that’s 14g of coffee to 225ml of water. This yields a balanced strength. For a single serve, use about 14g coffee per 175ml water. You can adjust the amount up or down depending on whether you prefer a stronger or milder cup.

How long should I steep coffee in a French Press?

Most brewers find 4 minutes to be optimal. Steeping for 3 minutes may under-extract, especially with lighter roasts, while 5 minutes or longer can over-extract, leading to bitterness—especially with dark roasts. Adjust based on your taste and bean type.

What water temperature is best for French Press brewing?

The recommended water temperature range is 85°C–95°C. If you don’t have a thermometer, letting boiled water sit for 2–3 minutes is a good rule of thumb. Water that’s too hot can scorch the coffee, creating harsh or bitter notes, while water that’s too cool may result in flat, under-extracted coffee.

Can I use finely ground coffee in a French Press?

You shouldn’t use finely ground coffee as it will pass through the metal filter, leading to a gritty, sludgy cup. Always use a coarse grind for French Press. Fine grinds are suited for espresso or Moka Pot brewing, not immersion methods like French Press.

Recommended FrontStreet Beans for French Press

For French Press brewing, FrontStreet Coffee recommends medium to dark roasted beans that highlight body and sweetness. Try the PWN Golden Mandheling, a carefully selected and medium-dark roasted single origin from Indonesia with bold notes of spice, caramel, and dark chocolate.
