The French Press Is Italian: Milan's Spring Seal and a Clarinet Factory

SPEAKER_1 (0:00)

If you walk into your kitchen right now, there is a very good chance you own a device that is essentially lying to you.

SPEAKER_2 (0:06)

Oh, absolutely lying to your face.

SPEAKER_1 (0:08)

Right, it's sitting there on the counter or maybe tucked in a cabinet somewhere, sporting a name that suggests this very neat, very tidy historical origin story. I mean, we call it a French press.

SPEAKER_2 (0:19)

Which naturally makes you assume the French get all the credit for perfecting it.

SPEAKER_1 (0:23)

Exactly, because it has that specific national identity just baked right into the name. But the truth is so much stranger. So, welcome to the Deep Dive.

SPEAKER_2 (0:31)

Glad to be here.

SPEAKER_1 (0:32)

We've gathered a stack of sources today. You know, design histories, encyclopedia entries, some really old historical patents. And our mission for you today is to unpack the surprisingly chaotic, multicultural history of this everyday tool.

SPEAKER_2 (0:46)

Yeah, and we're going to explore the specific physics of how it actually works, too.

SPEAKER_1 (0:50)

Right, and uncover the hidden versatility of this simple glass beaker that was, believe it or not, perfected by Italians, manufactured in a French clarinet factory, and this is my favorite part, propelled to global fame by a British spy movie.

SPEAKER_2 (1:03)

It really is the ultimate identity crisis in a glass cylinder. I mean, to really appreciate how this seemingly basic mechanism conquered the globe, we kind of have to look past its everyday utility.

SPEAKER_1 (1:15)

We have to rewind the timeline a bit.

SPEAKER_2 (1:18)

Right. Back to an era long before this device actually functioned properly.

Because the foundational concept was just riddled with mechanical flaws.

SPEAKER_1 (1:28)

But before we even touch on those mechanical flaws, we need to address the naming chaos. Because our sources highlight this really fascinating bit of human psychology.

SPEAKER_2 (1:37)

Oh, the regional names?

SPEAKER_1 (1:38)

Yeah. If you are listening to this in North America, you almost certainly call it a French press or maybe a coffee press. But if you travel to Australia, New Zealand or South Africa, this exact same device is universally known as a coffee plunger.

SPEAKER_2 (1:52)

A coffee plunger.

SPEAKER_1 (1:53)

And you drink plunger coffee.

SPEAKER_2 (1:55)

Which, I mean, it completely strips away all the romance, right? It just gives you this brutally literal description of the physical action.

SPEAKER_1 (2:03)

It totally does. But then you hop over to the UK or Ireland and it's a cafeteria, which just stems from the French word for coffee maker.

SPEAKER_2 (2:11)

Right.

SPEAKER_1 (2:11)

My favorite though comes from Germany. They use terms like press Stempelkanne or Stempelkanne, which translates to stamp pot.

SPEAKER_2 (2:18)

Stamp pot. Isn't that perfect? That is perfect.

SPEAKER_1 (2:21)

Yeah. If you think about it, stamp pot perfectly describes the actual mechanics of the device. The German and Australian names focus entirely on the physical reality of what the tool does.

SPEAKER_2 (2:33)

Well, the North American name just clings to this geography.

SPEAKER_1 (2:36)

Right. It's a brilliant example of how we prioritize a romanticized origin story over functional reality.

SPEAKER_2 (2:42)

Well, and the timeline of that origin story starts with a few scattered breadcrumbs really. The earliest notable one is from 1812

SPEAKER_1 (2:49)

Oh, right. Benjamin Thompson.

SPEAKER_2 (2:51)

Yeah, an inventor named Benjamin Thompson created an early drip press coffee brewing device. But, you know, that design was fundamentally different from the immersion brewing method we use today.

SPEAKER_1 (3:02)

So it wasn't a true French press.

SPEAKER_2 (3:04)

No, not really.

The true forerunner to the modern press didn't appear until 1852 And that one actually was in France.

SPEAKER_1 (3:11)

Okay, enter our two Frenchmen. We have a metal smith named Henri Audomère and a merchant named Jacques-Victor Delforge.

SPEAKER_2 (3:19)

Right.

SPEAKER_1 (3:19)

They partnered up and secured a patent for this brand new coffee device. The blueprint was essentially this flat metal screen, or sometimes just a piece of cheesecloth, attached to a long rod.

SPEAKER_2 (3:31)

Very recognizable to what we use now.

SPEAKER_1 (3:33)

Yeah, you drop your hot water and your coffee grounds into a pot, wait a bit, and then you physically push that screen down through the liquid to trap the grounds at the bottom. I mean, conceptually, it is brilliant.

SPEAKER_2 (3:43)

Conceptually, yes.

SPEAKER_1 (3:45)

But functionally?

SPEAKER_2 (3:46)

A total disaster.

SPEAKER_1 (3:48)

Yeah, a disaster waiting to happen.

SPEAKER_2 (3:49)

The Delforge-Meyer patent suffered from one fatal engineering flaw. It did not create a proper seal around the edges of the filter.

SPEAKER_1 (3:58)

Which renders the entire concept completely useless. I was trying to visualize this when reading through the sources, and the best analogy I can think of is using an umbrella in a torrential downpour, but the umbrella has a massive hole cut right out of the center.
