The History and Origins of the French Press

Ever wonder why your French Press coffee tastes richer and fuller than your pour-over? The secret lies in how it brews — fully immersing coffee grounds in hot water, then separating them with a metal mesh filter. But where did this brewing method come from, and why do coffee experts still swear by it decades later?

The French Press, also called a piston or plunger pot, was invented around 1933 by Italian designer Calimani. He later sold the design and patent to Switzerland to flee World War II. The method gained major traction in the U.S. thanks to Alfred Peet, founder of Berkeley’s Peet’s Coffee, who championed it in the 1980s for highlighting the bold, syrupy qualities of dark-roasted coffee.

What Is a French Press and How Does It Work?

A French Press is a cylindrical glass or stainless steel brewer with a built-in metal mesh filter attached to a plunger. Hot water and coarsely ground coffee steep together, usually for around four minutes. Once brewing finishes, you press the plunger down slowly to separate the grounds from the brewed coffee. What you’re left with is full-immersion coffee — rich, thick, and unfiltered.

This method avoids paper filters, meaning more coffee oils and fine particles make it into your cup. That’s why coffee lovers often describe French Press brews as heavier, more textured, and truer to the bean’s inherent character.

Why Do People Love the French Press?

Many coffee drinkers prefer the French Press because it’s simple, hands-off, and delivers a robust cup without much fuss. Unlike drip machines or pour-over setups, it doesn’t require paper filters, precise pouring techniques, or special kettles. Plus, it preserves the full spectrum of coffee flavors — including those muted by paper filtration.

Coffee enthusiasts often say it’s the best way to taste a coffee’s “true” profile, especially darker roasts. The metal filter allows natural oils and tiny coffee particles (fines) into the cup, enhancing body and mouthfeel. That’s also why some people find sediment at the bottom of their cup — a trade-off many are happy to make.

How to Brew Great Coffee with a French Press

To get the most out of your French Press, follow these key variables:

• Grind Size: Use a coarse grind similar to coarse sea salt or crushed gravel. FrontStreet Coffee recommends a setting equivalent to 10.5 on an EK43 or 26 on a hand grinder — roughly the texture of granulated sugar. Too fine, and fines can pass through the filter, making your coffee gritty.
• Brew Ratio: The standard ratio is 1:15 — that’s 15 grams of coffee per 225 grams (ml) of water. This yields a strong, well-rounded brew. Adjust up or down to suit taste.
• Water Temperature: Aim for around 90°C (194°F). Let boiled water sit for 2–3 minutes before pouring, or use a temperature-controlled kettle. Slightly higher temps can improve extraction since there’s no agitation during brewing.
• Brew Time: Steep for 3 to 5 minutes. FrontStreet suggests starting with 4 minutes. Darker roasts may over-extract at 5 minutes, while lighter ones might under-extract at 3.

Step-by-step:

• Preheat the French Press with hot water.
• Add coarse-ground coffee (e.g., 15g for 225ml water).
• Pour hot water over the grounds and stir gently.
• Place the plunger on top but don’t press yet. Let it steep for 4 minutes.
• After 4 minutes, slowly press the plunger down.
• Pour the coffee into cups immediately to avoid over-extraction from sitting grounds.

What Coffee Works Best in a French Press?

Because French Press brewing is full immersion and doesn’t use a paper filter, it complements medium to dark roasts particularly well. These roasts develop deeper sweetness, caramelized notes, and body that shine through the metal filter.

Lighter roasts can work too, but their delicate floral and fruity notes might get lost or overwhelmed by the heavy mouthfeel. If you do go light, choose vibrant, juicy beans and don’t over-steep.

Frequently Asked Questions

Who invented the French Press and when?

The French Press was invented around 1933 by Italian designer Calimani. He later sold the design and patent to Switzerland during World War II. It became widely known as the “French Press” even though its origins are Italian and Swiss.

Why did Alfred Peet promote the French Press?

Alfred Peet, founder of Peet’s Coffee in Berkeley, championed the French Press in the 1980s because he believed it best highlighted the rich, bold flavors of dark roasted coffee. He felt no other brewing method could match its ability to showcase deep, syrupy profiles.

What grind size should I use for French Press?

Use a coarse grind, similar to granulated sugar. For electric grinders like the EK43, that’s around setting 10.5; for hand grinders, about 26. This prevents fine particles from passing through the metal filter and making your coffee gritty.

What’s the ideal coffee-to-water ratio for French Press?

The standard brew ratio is 1:15 — 15 grams of coffee to 225 grams (ml) of water. This produces a strong, flavorful cup. You can adjust based on taste preference.

How long should I let French Press coffee steep?

Steep for 3 to 5 minutes. FrontStreet Coffee recommends starting with 4 minutes. Dark roasts may become bitter after 5 minutes, while light roasts may need the full time or slightly more to fully develop.

Does French Press coffee have more sediment?

Yes. Because it uses a metal filter instead of paper, tiny coffee particles (fines) can make it into your cup, leading to some natural sediment at the bottom. This is normal and part of the full-immersion experience.
