What Makes a Good Italian Espresso?

You sit down at a cafe, order an espresso, and watch as the barista pulls a small, dark shot into a tiny cup. But how do you know if what you’re about to drink is any good? Is it just about taste, or are there clear signs of a properly made espresso?

A good Italian espresso has three key traits: a thick, reddish-brown crema covering the surface, a lingering aroma left in the cup after drinking, and strong crema that clings to the sides of the cup — known as ‘cup retention’ or ‘coffee film.’

What Is an Espresso, Really?

In Italian, ‘espresso’ means ‘fast and exceptional.’ This style of coffee is meant to be consumed quickly — ideally in three sips or fewer — from a small demitasse cup, and always without milk or sugar. Its entire purpose is to deliver pure, intense coffee flavor directly to your palate. That intensity is why so many specialty coffee drinkers start their journey here.

Why Crema Matters So Much

The crema is the reddish-brown foam that floats on top of a well-brewed espresso. It’s not just cosmetic — it’s packed with aromatic compounds and signals that the extraction has gone well. This layer is created during extraction when pressurized hot water forces carbon dioxide out of freshly ground coffee, emulsifying coffee oils and trapping tiny air bubbles. The result is a dense, caramel-colored foam. In traditional Italian cafes, a lack of crema can even be grounds to refuse payment.

How to Judge Espresso Quality

A truly great espresso shines in three specific areas:

• Crema Appearance: A high-quality shot will have a thick, rich, reddish-brown (not pale or blonde) layer of crema on top. This indicates proper pressure, fresh coffee, and correct grind size.
• Cup Retention (Crema Sticking to the Cup): After you finish the shot, look at the inside of the cup. Good espresso leaves a noticeable brown residue or ‘film’ along the edges where the crema touched the cup. More crema residue = better extraction and freshness.
• Aroma After Drinking: A well-prepared espresso leaves a pleasant, lingering coffee aroma in the cup even after it’s been drunk. This is another mark of a balanced, well-developed shot.

What Creates Good Crema and Extraction?

Crema forms due to a mix of factors during espresso extraction under 9 bars of pressure at around 90–96°C. Water passes through finely-ground coffee, extracting soluble solids, emulsifying coffee oils, and incorporating CO₂ — especially important in freshly roasted beans. The result is a stable foam with microbubbles. Darker roasts tend to produce more crema due to higher solubles and gases, though balance is key. Too dark, and the cup may become bitter and oily; too light, and crema may be thin or absent. Freshness matters enormously — older beans lose CO₂ and oils, reducing crema potential.

Frequently Asked Questions

What does a good espresso crema look like?

A good espresso crema is reddish-brown (not pale or tan), thick, and creamy in texture. It should cover the entire surface of the shot and remain dense rather than dissipating instantly. Pale or bubbly crema usually means under-extraction, old beans, or incorrect grind pressure.

Why is crema important in espresso?

Crema contributes significant aroma and flavor compounds and indicates proper extraction technique. It’s a visual and sensory signal that the espresso was brewed at the right pressure, temperature, and with fresh, well-ground coffee. It also enhances mouthfeel.

Does espresso need to have crema to be good?

While crema is not the sole judge of espresso quality, its presence is a strong indicator of a properly extracted shot. Many traditionalists consider a lack of crema a flaw, and in some places, it’s even acceptable to refuse a poorly crema-ed espresso.

How do you get good crema every time?

To achieve consistent crema, use freshly roasted coffee, grind it finely, ensure proper tamping, maintain consistent water temperature (around 90–96°C), and pull the shot at around 9 bars of pressure. The coffee should be medium to dark roast for optimal results.

What does cup retention mean in espresso?

Cup retention refers to the coffee oils and crema residue that stick to the inside walls of the cup after drinking. A good espresso leaves visible brown ‘film’ or staining inside the cup, showing strong extraction and a well-formed crema.
