Espresso: 30 seconds in which everything comes together

At Falco Caffè, we believe that good coffee is no accident. Especially espresso. What looks like a small cup of coffee is actually the result of precision, attention, and respect for the product. In the 25 to 30 seconds it takes to make an espresso, everything comes together: bean, roasting, grinding, machine, and human touch.

When water at approximately 93 °C and a pressure of 9 bar hits the coffee bed, a precise extraction process begins. In the first few seconds—the pre-infusion—the ground coffee is evenly saturated. The most soluble substances are released first: fresh acids and light aromas. The first drops that appear are therefore sharp and distinctly acidic.

Then comes the heart of the espresso. Between approximately 7 and 20 seconds, balance is achieved. Sugars dissolve, bringing sweetness and body. Aromas developed during roasting—think chocolate, caramel, and nutty notes—come to the fore. The natural oils from the coffee mix with the water, creating crema and mouthfeel. This is when espresso gains depth, complexity, and character.

If you allow the extraction to continue for too long, the balance shifts. Heavier, bitter components take over. If you stop too early, the espresso remains thin and sour. Making espresso is therefore not a matter of speed, but of timing. Extract just enough from the middle, without too much from the extremes.

What an espresso machine actually does

Espresso machines are technically impressive, but their core is surprisingly simple. Ever since the classic commercial machines of the late 1980s, it has been all about two things: stable temperature and constant pressure. Water around 93 °C, with approximately 9 bar pressure through the coffee.

All subsequent innovations—precise temperature control, volumetric dosing, and pressure profiling—are refinements of that basic principle. They make the process more consistent and repeatable, but do not change its essence.

In the 1990s, fully automatic machines made espresso accessible to a wide audience. They took over the grinding, dosing, and extraction processes entirely. This brought convenience and consistency, but also limitations. Not every coffee requires the same approach. A lightly roasted Ethiopian coffee needs a different approach than a dark Italian roast, and you can only make that distinction if you can adjust the settings.

That is why quality-oriented coffee bars work with machines that combine stability with flexibility. Because true quality requires choices, not a fixed button. But when it comes to a fixed choice of a beautiful premium coffee and ease of use, today's fully automatic machines are indispensable.

Why espresso became the basis for milk drinks

Cappuccino, latte, flat white, or cortado: they differ in milk and texture, but share the same basis. Espresso. Not out of tradition, but out of necessity.

Espresso is extremely concentrated. Compared to filter coffee, it contains eight to twelve times more dissolved coffee substances. This means that the coffee flavor remains intact, even with a generous amount of milk. Filter coffee disappears in milk; espresso carries through it.

Temperature also plays an important role. Espresso is brewed hot and served immediately. This means that a milk drink starts out warm and stays warm, which is essential for sweetness, texture, and drinking comfort.

A persistent misunderstanding

For a long time, it was thought that dark roasting was synonymous with good espresso. That idea didn't come out of nowhere: dark-roasted coffee is easier to extract, forgiving, and consistent. But what was overlooked was what gets lost along the way.

A high-quality bean naturally carries its origin within it: floral notes, fresh fruit, soft sweetness, or deep chocolate tones. However, by roasting beans to an extremely dark level, these characteristics are literally burned away. What remains is a uniform taste of carbonization and bitterness. Whether the bean came from Ethiopia, Colombia, or Brazil, after such roasting, everything tasted the same.

For decades, this profile was marketed as "espresso." Entire generations grew up with it, fed by supermarket and mass market logic: cheaper beans, long roasting, hiding flaws, and still participating in the espresso market. Dark, bitter, and strong became the norm—not because it was better, but because it was easier.

The premium and specialty coffee movement broke that pattern. They showed that espresso is not a roast level, but a brewing method. Lighter roasted coffees proved to be excellent for espresso, provided you respected and adapted the process: grinding slightly coarser, extracting slightly longer, and sometimes using a slightly higher temperature. The result was espresso that finally tasted like its origins again—floral, fruity, elegant, or deep and chocolatey.

That insight changed everything. Espresso turned out not to be an excuse to hide flavor, but rather a magnifying glass that reveals quality. Any coffee can shine in it, as long as you are willing to take the variables seriously and let the bean speak for itself instead of drowning it out.

What really matters to us

Espresso leaves nothing to chance. In 30 seconds under high pressure, everything becomes apparent: the quality of the bean, the freshness of the roast, the precision of the grind, and the attention of the person making it. Nothing can be hidden.

That's precisely why we're sharing this story. Not to make things complicated, but to show that good coffee starts with understanding. With knowing what you're doing and why you're doing it. At Falco Caffè, we want to help our customers make better choices—whether that's about the coffee you drink, the way you brew it, or the expectations you have of an espresso.

Machines have become more sophisticated and knowledge has deepened, but the essence has remained unchanged since the first lever machines of the 1940s: hot water, high pressure, precise timing, and attention to detail.

Everything else is just nuances.
And it is precisely those nuances that create a truly good espresso.
