Visiting the Birthplace of Espresso in Trieste

It was your first day in Geneva, jet-lagged and running late for an interview. You asked for ‘coffee, fast’ and were handed a tiny cup of espresso. You drank it like a shot of tequila—then felt its intense jolt race to your brain. That’s espresso: small, fast, and powerful. But where did it come from, and why does it hit so hard?

The word ‘espresso’ means ‘made for you immediately’ in Italian. It’s a concentrated coffee extracted under pressure, meant to be drunk right after brewing. Every element—from water temp to pressure—affects its iconic 3mm crema and bold flavor. Here’s how it works, where it began, and how to really enjoy it.

What Exactly Is Espresso?

Espresso is a small, concentrated coffee brewed by forcing hot water (around 90°C) through finely-ground coffee under high pressure—typically 9 atmospheres. The result is a 1-ounce (30ml) shot with a rich, dark brown crema layer about 3mm thick. It’s the base for drinks like cappuccino and latte, but also meant to be enjoyed solo.

The Birthplace: Trieste, Italy

Trieste, a port city in northeast Italy, is the true home of espresso. The local coffee culture is deeply rooted, with historic cafés dating back to the 19th century and lively coffee scenes from morning until night. It’s here that Francesco Illy, founder of illycaffè, invented the first automatic espresso machine, the Illetta, in 1935. This machine replaced steam with compressed air, revolutionizing how espresso was brewed and paving the way for modern coffee machines.

The city’s coffee culture is inseparable from its history. Cafés are everywhere, serving as social hubs where people gather over espresso. The espresso you drink in Trieste isn’t just coffee—it’s a ritual, a quick jolt to start the day, often shared in a few sips before moving on.

How Espresso Is Made—And Why It Matters

Making espresso is both a science and an art. At its simplest, you can use a moka pot, but that often leads to over-extraction and bitterness. For true espresso, you need a machine capable of producing 9 bars of pressure and maintaining a water temperature around 90°C.

At illy’s factory, the process is meticulously controlled: 15 coffee beans are ground to 7 grams, tamped into a portafilter, and brewed for exactly 25 seconds. The goal? A shot with a thick, stable crema and balanced flavor. The precision matters—grind size, dose, tamp pressure, and brew time all influence extraction. Too long, and you get bitterness; too short, and it’s sour and weak.

The crema isn’t just for show—it’s a mix of emulsified oils, CO₂, and tiny bubbles that carry aroma and affect mouthfeel. A good crema holds for minutes, slowly fading into spots if left too long. Once the crema dissipates, so does the espresso’s optimal flavor window.

How to Drink Espresso—And What You’re Really Tasting

Espresso is best enjoyed fresh and hot. Sip it right after brewing to experience its full crema, balance, and intensity. Over time, the crema breaks down, and the coffee turns more acidic and bitter. Drinking it plain lets you taste its layers—bitterness, sweetness, body—but many pair it with a lemon slice or sweet pastry to cut through the intensity.

Flavor-wise, espresso delivers a concentrated experience: you taste more bitterness, but also deeper sweetness and complexity. Most of what you perceive as ‘taste’ actually comes from smell—up to 70% of coffee’s flavor notes are aromatic. Pinch your nose while drinking espresso, and you’ll notice how much is lost. The texture of the crema, the sound of the pour, even the warmth of the cup all contribute to the experience beyond just taste.

Frequently Asked Questions

What does the word 'espresso' mean in Italian?

In Italian, 'espresso' translates to 'made for you immediately,' referring to coffee brewed on demand. It implies speed, freshness, and a concentrated extraction designed for quick consumption.

Where was espresso actually invented?

Espresso was developed in Italy, with key innovations taking place in Trieste. Francesco Illy invented the first automatic espresso machine, the Illetta, there in 1935, using compressed air instead of steam to brew coffee under pressure.

What is crema, and why is it important?

Crema is the golden-brown foam layer on top of a well-brewed espresso, about 3mm thick. It’s formed by emulsified coffee oils, CO₂, and tiny bubbles, contributing to aroma, flavor, and mouthfeel. Good crema lasts a few minutes before breaking into dots.

Can you make real espresso without a machine?

You can try with a moka pot, but it usually results in over-extracted, bitter coffee. True espresso requires 9 bars of pressure and precise temperature control, which most home devices can’t achieve. A proper espresso machine is ideal.

How should you drink espresso properly?

Drink espresso quickly, while it’s hot, to enjoy the full flavor and crema. Letting it sit makes it more bitter. Many Italians drink it plain, but you can pair it with a lemon slice or pastry to balance the intensity.

Why is espresso so bitter compared to other coffee?

Espresso is more concentrated and brewed under pressure, extracting more bitter compounds along with sweetness and body. The small serving size intensifies its bold flavors, which may taste harsh if over-extracted or not fresh.
