Espresso Crema: Flavor, Beans, and Caffeine Facts

Ever scooped the golden-brown foam off your espresso and thought the coffee tasted better? You’re not alone—many notice that removing the crema makes the shot taste less bitter and more sweet. But is that really the best way to enjoy espresso? Let’s break down what crema is, why some people swear by it, and what really affects its presence and quality.

The short answer? Traditional Italian espresso standards say a proper shot should have a crema that’s hazelnut to dark brown, with hints of yellowish-brown and an extremely fine texture. Without it, purists say, it’s not a true espresso. But modern tastes and lighter roasts are shifting those ideas, too.

What Is Crema, Really?

Crema is the creamy, caramel-colored layer sitting on top of a well-pulled espresso. It’s not just foam—it’s a mix of carbon dioxide, tiny coffee oils, plant lipids, sugars, and air bubbles. These elements come together under high pressure (around 9 bars) and controlled temperature during extraction. The result is a layer that looks dense but is actually made up of microscopic bubbles. This crema doesn’t just sit there looking pretty—it affects how the espresso tastes and feels in your mouth.

Why Crema Tastes Bitter—And Why Some Love It

Yes, crema can taste quite bitter, often more so than the espresso beneath it. That’s because it holds some of the harshest, most soluble bitter compounds extracted early in the shot. But here’s the twist: while removing the crema may make your espresso taste noticeably sweeter, traditionalists argue you’re missing out on essential texture and aroma. In milk drinks like lattes or cappuccinos, crema plays a major role in the overall flavor profile—even though it gets diluted. As Australian Barista Champion and judge Craig Dixon notes, “The majority of the flavor in milk coffee comes from the crema.”

What Determines Crema Quality and Color?

According to Italy’s National Espresso Institute, ideal espresso crema should be hazelnut to dark brown, with some yellowish strands and a very fine, almost velvety texture. Over the years, judging criteria have evolved. Craig Dixon, who has judged the Australian Barista Championships for a decade and won four times, says that in the past, judges looked for deep brown or hazelnut crema. But with the trend toward lighter roasts, the crema has gotten lighter, too—and judges now focus more on the roaster’s prediction of crema rather than enforcing a rigid color standard.

Does Processing Method Affect Crema?

Some assume that natural (dry-processed) beans produce more crema than washed (wet-processed) beans. But Dixon says you can’t reliably judge processing method by crema alone. What you can tell from crema is freshness. Freshly roasted coffee releases more CO₂, leading to a thicker, more stable crema. But if the coffee is straight out of the roaster, too much CO₂ can cause the crema to dissipate too quickly. On the other hand, coffee that’s more than three weeks off-roast—past its “golden” 21-day window—will produce weak, thin crema that lacks body and aroma.

How to Make Great Crema at Home

If you’re pulling shots at home and want that classic crema, here’s what to do:

• Use freshly roasted coffee beans from a local roaster—not supermarket stock.
• Grind only the dose you need for one shot, and make sure your grinder is completely purged of old coffee.
• Aim for a medium to medium-fine grind suitable for espresso (around 20–25 grams per double shot, extracted in 25–30 seconds).
• Brew at around 9 bars of pressure with water at 90–96°C.

Coffee equipment matters, too. Avoid toy machines or low-end automatics that can’t sustain stable 9-bar pressure—the resulting “crema” might look similar but will lack the texture, stability, and flavor complexity of true espresso crema.

Do Darker Roasts Always Make More Crema?

Darker roasts typically produce more visible crema because they release more oils and gases. Blends with a small percentage of Robusta—like FrontStreet Coffee’s Classic Blend or Commercial Blend—also tend to have richer crema due to Robusta’s higher caffeine and chlorogenic acid content, plus its natural oiliness. However, roast too dark and the coffee may start releasing free oils that don’t emulsify properly, leading to greasy residue instead of stable crema. Medium-dark roasts (like PWN Golden Mandheling or Brazil Queen Manor beans) often hit the sweet spot for balanced crema and flavor.

Frequently Asked Questions

Does removing espresso crema make the coffee taste better?

Yes, many people find that removing the crema results in a sweeter-tasting shot because the bitter compounds concentrated in the crema are left behind. However, traditionalists argue that crema contributes essential texture, aroma, and complexity to the espresso experience.

What color should good espresso crema be?

According to Italy’s National Espresso Institute, ideal crema should range from hazelnut to dark brown, with some yellowish-brown streaks and a very fine, smooth texture. Modern lighter roasts may produce paler crema, which is increasingly accepted in competitions.

Does coffee processing method affect crema?

No, you can’t determine whether coffee is washed or natural just by looking at the crema. However, crema does indicate freshness—freshly roasted coffee generally produces thicker, more stable crema due to higher CO₂ levels.

How can I get better crema at home?

Use freshly roasted beans, grind right before brewing, and ensure your espresso machine maintains 9 bars of pressure with water at 90–96°C. Avoid pre-ground coffee and low-quality machines that can’t generate proper pressure for true crema formation.

Do Robusta beans produce more crema than Arabica?

Yes, Robusta beans typically create more visible and thicker crema due to their higher oil content, greater gas release, and denser structure. Many espresso blends include a small percentage of Robusta for this reason.

Is crema necessary for a good espresso?

Not strictly necessary, but traditional espresso aficionados consider crema an essential component of a well-made shot. It contributes to texture, aroma, and mouthfeel, especially in milk-based drinks. Without it, you might as well be drinking filtered coffee.
