Trieste: Birthplace of the Espresso

In a city where mornings begin with a quick shot of dark intensity, espresso isn’t just coffee — it’s a ritual. But have you ever wondered where espresso really began, and why every cup disappears so fast? The answer lies in Trieste, Italy, the true birthplace of the espresso we know today.

Espresso was invented to deliver a concentrated shot of coffee quickly under pressure — and it must be drunk right after brewing, ideally within 25 seconds, to enjoy its full flavor and crema. Trieste gave the world the first practical espresso machine, thanks to Francesco Illy’s 1935 innovation, the Illetta.

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. This process extracts a bold shot with a rich, aromatic crema about 3mm thick. The entire brew should take around 25 seconds to avoid over-extraction, which leads to bitterness.

The Birthplace of Espresso: Trieste

Trieste, a port city in northeast Italy, is where modern espresso was refined and popularized. It was here that Francesco Illy, founder of the illycaffè brand, invented the first automatic espresso machine using compressed air instead of steam — the Illetta, in 1935. This innovation marked one of three historic breakthroughs in coffee technology attributed to illy, alongside pressurized coffee preservation and instant coffee pods.

The city remains steeped in coffee culture. Its streets are lined with historic cafés, many dating back to the 19th century, where locals sip espresso from morning till night. The term 'espresso' itself means 'fast' or 'immediately prepared for you' in Italian — reflecting both the speed of the brew and the urgency with which it should be consumed.

Why You Can’t Make Great Espresso at Home (Easily)

Making espresso requires precision few home setups achieve. While a basic moka pot can produce a strong coffee, it uses steam pressure (over boiling point), often resulting in over-extracted, bitter shots. True espresso demands professional-grade equipment: a machine capable of at least 9 bars of pressure, stable 90°C water temperature, and proper tamping tools.

At the illy factory, the espresso-making process is tightly controlled: 15 beans are ground to 7 grams, tamped, and brewed for exactly 25 seconds. The result is a 3mm crema atop a rich, balanced shot. Without the right grind size, pressure, water flow, and timing, you’re likely to end up with something far from the authentic experience.

How to Drink Espresso the Italian Way

Espresso is meant to be sipped quickly while hot. Letting it sit causes the crema to break down and the flavors to turn sour or overly bitter. Drinking it straight — known as a single espresso — is common throughout Europe. In many cafés, ordering just 'coffee' will get you an espresso by default.

If the intensity is too much for your palate, pair it with a slice of fruit mousse cake or a glass of lemon water to cleanse your taste buds. The bitterness is part of the experience — coffee experts describe it as rich, lingering, and deeply satisfying. In fact, they argue that aroma contributes up to 70% of coffee’s flavor perception, while taste accounts for only around 15%. That’s why drinking espresso with your nose plugged dramatically dulls the experience.

Beyond taste and smell, true espresso appreciation engages all senses: the sight of crema and cup design, the sound of extraction and cup placement, and even the warmth of the cup against your skin. It’s an immersive ritual that transcends mere caffeine intake.

The Everyday Ritual in Trieste

In Trieste, espresso is a social punctuation mark. Locals duck into cafés, order a shot, chat briefly, then drink it swiftly before continuing their day. Men often take it straight and black, while women may add sugar or a touch of milk. Each cup carries not just caffeine, but a brief moment of connection and routine — the concentrated essence of daily life.

Frequently Asked Questions

Where was espresso actually invented?

Espresso as we know it was developed and refined in Trieste, Italy. While early steam-based machines existed earlier, the modern espresso — brewed under pressure with a thick crema — was made practical by Francesco Illy’s 1935 invention of the Illetta machine in Trieste, which used compressed air instead of steam.

What is the ideal brewing time for espresso?

The optimal espresso extraction time is around 25 seconds. This timing, using around 9 atmospheres of pressure and water at approximately 90°C, ensures proper flavor balance without over-extracting bitter compounds. Going over this time often results in a burnt or overly harsh taste.

What is crema and why is it important?

Crema is the golden-brown, creamy layer that forms on top of a well-brewed espresso shot. Ideally 3mm thick, it’s a mix of emulsified oils, CO2, and tiny bubbles created during extraction. Crema enhances aroma, texture, and flavor, and is a key indicator of a properly brewed espresso.

Can you make espresso without a machine?

You can’t make true espresso without a machine capable of at least 9 bars of pressure. Devices like moka pots use steam pressure and produce a stronger coffee, but not a genuine espresso with crema. For home brewing that approximates espresso, you need a machine or advanced setup that meets pressure and temperature requirements.

Why must espresso be drunk quickly?

Espresso is best enjoyed immediately after brewing. Over time, the crema dissipates, and the coffee cools, causing acidity and bitterness to become more pronounced. The full sensory experience — including aroma and mouthfeel — peaks right after pouring and fades within about 25 to 30 seconds.

Is espresso stronger than regular coffee?

Espresso has a higher concentration of coffee solids per volume, making it stronger in flavor and caffeine content per ounce. However, a standard single espresso shot (about 30ml) usually contains less total caffeine than a typical 8-ounce drip coffee, though the intensity is much greater.
