AeroPress-Style French Press: A Stronger Brewing Method

If you’ve ever poured yourself a cup of French press coffee only to find it overly bitter, sludgy, or thin, you’re not alone. Many home brewers struggle to get a clean, full-bodied cup without over-extraction or excessive sediment. The usual culprit? Incorrect grind size, wrong brew time, or poorly filtered coffee. What if you could make a French press coffee that’s richer, cleaner, and more controlled—almost like an AeroPress, but with the familiar ease of a press pot?

The key is to use a coarse grind (like coarse sugar or EK43s setting 10.5 / hand grinder 26), a 1:15 coffee-to-water ratio (e.g., 15g coffee to 225g water), steep for around 4 minutes, and pour water at roughly 90°C. These adjustments help extract bold flavours while minimising grit and bitterness.

What Makes French Press Different?

French press coffee is made through full immersion brewing, meaning coffee grounds sit in hot water for several minutes before being filtered out. Unlike pour-over methods, there’s no constant flow or drainage—just soaking and separation. The metal filter allows more oils and fine particles into your cup, giving a heavier mouthfeel and often more body. But that same filter also lets tiny coffee particles through, which can lead to a muddy cup if not managed properly.

The result is a coffee that’s typically fuller and more robust than filtered methods, but also more prone to over-extraction, bitterness, and sediment if the grind is too fine or the steep too long.

Why Grind Size and Steep Time Matter

French press relies on time, not turbulence, to extract flavour. That means your grind size directly affects how quickly compounds dissolve into the water. A grind that’s too fine extracts too fast, pushing bitter tannins and unwanted flavours into your cup. A proper French press grind should be coarse—think small gravel, not sand. For example, FrontStreet Coffee recommends using a setting similar to coarse sugar: EK43s at 10.5, or a hand grinder at 26.

If you want more complexity, you can experiment with a slightly finer grind—but reduce the brew time accordingly to avoid over-extracting. The standard brew time is around 4 minutes. For lighter roasts, 3 minutes may not fully develop the flavours, while darker roasts can turn harsh after 5 minutes.

How to Brew Better French Press Coffee

To make a better cup, follow this refined method inspired by AeroPress principles but adapted for the French press:

• Grind: Use a coarse grind resembling coarse sugar. On an EK43s, set to 10.5; for hand grinders, around 26. This helps reduce sediment and over-extraction.
• Dose & Ratio: Start with 15g of coffee to 225g (225ml) of water—a 1:15 brew ratio. This yields a strong yet balanced cup, typically with a TDS around 1.1–1.2%.
• Water Temperature: Heat your water to a rolling boil, then let it sit for 2–3 minutes (adjust based on room temp). Target around 90°C. For more control, use a gooseneck kettle with a thermometer. A slightly higher temp can improve extraction without added agitation.
• Brewing Steps:
  1. Remove the plunger and add your ground coffee to the empty French press.
  2. Pour in the hot water (15g coffee to 225g water), and stir gently to ensure even saturation.
  3. Place the plunger back on top—but don’t press yet. Let the coffee steep for 4 minutes.
  4. After 4 minutes, slowly press the plunger down. Move steadily to avoid channelling or disturbing the grounds.
  5. Pour the coffee into your cup immediately to avoid further extraction from the settled grounds.

By controlling these variables—grind size, ratio, temperature, and time—you’ll get a cleaner, more refined cup that still has the full body and richness French press is known for.

Bean Choice: What Works Best?

Because French press is an immersion method with extended contact time, medium to dark roasts tend to perform better. Lighter roasts can taste overly acidic or grassy if their delicate aromatics aren’t extracted gently. Darker roasts bring out chocolatey, caramel, and spicy notes that pair well with the method’s inherent body.

Coffees with lower acidity and bold flavours—like FrontStreet’s PWN Golden Mandheling or Strawberry Candy Espresso—shine in a French press. Avoid very light, fruity single origins unless you’re going for a deliberately intense, juicy cup and are willing to fine-tune your grind and time.

And if milk is your thing, the heavier mouthfeel of French press coffee makes it a great base for lattes or flat whites. Just remember: the better your grind control and brew technique, the better your finished cup.

Frequently Asked Questions

What’s the best grind size for French press?

The recommended grind size is coarse, similar to coarse sugar. For an EK43s electric grinder, use setting 10.5; for a hand grinder, around 26. This mimics small gravel—not fine sand. A coarser grind reduces over-extraction and prevents fine coffee particles from passing through the metal filter.

What coffee-to-water ratio should I use?

A standard and reliable ratio is 1:15—that’s 15g of coffee to 225g (millilitres) of water. This usually produces a brew strength of around 1.1–1.2% TDS, offering a rich and full-bodied cup. Adjust up or down based on your taste preferences.

How long should I steep French press coffee?

Most brewers get the best results with a 4-minute steep. Lighter roasts might need closer to 3 minutes to open up, while dark roasts can become bitter if left for 5 minutes or more. Start with 4 minutes and adjust based on taste.

What water temperature is ideal?

Let boiled water rest for 2–3 minutes before pouring—that’s roughly 90°C. If you lack a thermometer, aim for water that’s no longer boiling but still very hot. Slightly higher temperatures can improve extraction, especially with darker roasts.

Can I use a finer grind in French press?

Yes, but only if you’re aiming for more complexity and are willing to reduce brew time to avoid over-extraction. A finer grind extracts faster, which can lead to bitterness and more fines in your cup. If you go finer, steep for less time—perhaps 3 minutes—and expect more sediment.
