Espresso: The Classic Italian Coffee Drink

If you’ve ever watched an Italian sip a tiny black coffee with a thick layer of foam on top and wondered how they make it look so effortless—and taste so bold—you’re not alone. The espresso is more than just a strong coffee. It’s a precise ritual, a balance of time, pressure, and texture that delivers a bold shot with a defining crema.

The classic Italian espresso takes 25 seconds to brew and is served in a 70ml cup, topped with a layer of crema. That’s the gold standard: short, strong, and finished with a rich, caramel-colored foam on top.

What Exactly Is Espresso?

Espresso is a concentrated coffee brewed by forcing hot water under pressure through finely-ground coffee. Originating in Italy, it’s the base for drinks like cappuccinos, lattes, and macchiatos—but on its own, it’s a 25-second, 70ml shot with a thick, aromatic crema.

What You Need to Make a True Espresso

To pull a classic espresso, you need just three components:

• Coffee beans: Fresh, finely-ground espresso beans are essential. The roast level and grind size determine the flow rate and flavor extraction.
• Sugar (optional): Though not traditional in modern espresso culture, sugar is sometimes added at the table for personal taste.
• 70ml cup: The ideal serving vessel is a small cup holding around 70 milliliters, which allows the espresso to maintain optimal temperature and concentration.

The 25-Second Extraction Rule

The hallmark of a well-brewed espresso is the 25-second extraction time. This window ensures that the water pulls enough soluble compounds from the coffee grounds to develop body, sweetness, and complexity—without over-extracting bitter flavors. Timing is critical and should be measured from the start of the extraction until it finishes.

What Is Crema and Why Does It Matter?

Crema is the golden-brown foam that sits on top of a properly extracted espresso. Formed by the emulsification of coffee oils, carbon dioxide, and proteins under pressure, it’s a visual and sensory indicator of a successful shot. Good crema is velvety, persistent, and contributes to the aroma and initial flavor impression. Without it, something in your grind, dose, or pressure likely needs adjusting.

How to Make Espresso: The Basic Steps

Though modern espresso machines automate much of the process, the fundamentals remain simple:

1. Grind fresh coffee beans to a fine consistency suitable for espresso (typically a very fine grind, akin to powdered sugar).
2. Dose the ground coffee into a portafilter—usually around 7 to 9 grams for a single shot.
3. Tamp the coffee evenly and firmly to create a level, compact puck.
4. Lock the portafilter into the machine and place a 70ml cup underneath.
5. Press the button—or start the pump—and allow the machine to pull a shot for approximately 25 seconds.
6. Watch for the emergence of crema and stop the extraction once you’ve reached roughly 30ml of liquid for a ristretto, or let it fill to around 70ml for a standard single espresso.

Note: The article simply states “press the button, brew a shot of espresso”—but behind that button press is a carefully controlled process involving grind size, dose, tamp pressure, and machine pressure, typically around 9 bars.

Common Espresso Myths and Mistakes

Many people think espresso is just “really strong coffee,” but there’s much more to it. Using pre-ground coffee, an incorrect grind size, or poorly tamped coffee can lead to under- or over-extraction, resulting in sour or bitter shots without crema. Likewise, using too large a cup or pulling the shot too quickly or slowly will ruin texture and flavor. Timing, temperature, and technique all matter.

Frequently Asked Questions

What is the ideal extraction time for espresso?

The ideal espresso extraction time is 25 seconds. This timing helps achieve balanced flavor, proper body, and a good crema without extracting overly bitter compounds.

Why is crema important in espresso?

Crema is a layer of golden-brown foam on top of espresso, formed during extraction. It indicates proper brewing and contributes to aroma, mouthfeel, and flavor. Good crema is smooth, rich, and persistent.

What size cup is best for serving espresso?

The classic serving size for espresso is 70 milliliters. This cup size helps preserve the temperature and intensity of the shot while allowing proper crema formation.

Can you make espresso without a machine?

Authentic espresso requires high pressure (around 9 bars), which most manual or non-machine methods can’t achieve. While alternatives like AeroPress or moka pots can make strong coffee, they don’t replicate true espresso.

What kind of coffee beans should I use for espresso?

Use freshly roasted, medium to dark roasted coffee beans ground to a fine consistency. The beans should be specifically suited for espresso brewing to ensure proper extraction and crema development.

Is adding sugar to espresso traditional?

While sugar is sometimes added to espresso by personal preference, especially in some European countries, it is not part of the traditional espresso preparation method and is usually added after brewing.
