Is More or Less Coffee Crema Better? Why Does Espresso Have No Crema? What Does Crema Mean?

Crema, that layer of golden foam, is a distinctive characteristic of pressurized coffee, and it can sometimes help us identify certain problems.

Many friends often run into espresso that lacks crema. As we all know, crema is primarily composed of carbon dioxide and coffee bean lipids. If the espresso is extracted from light-roast beans with less carbon dioxide, then insufficient crema would be considered normal. But if we use dark-roast beans rich in carbon dioxide and still get little crema, FrontStreet Coffee believes it is likely due to these two reasons.

1. The Grind Is Too Coarse

If the extracted espresso has little crema and the coffee flows extremely quickly during extraction, we can basically conclude that the grind setting is too coarse. Because of the large particle size, the gaps between grounds increase, letting hot water pass through easily even when tamped firmly.

With low resistance, the coffee liquid permeates quickly, so the machine naturally will not apply excessive pressure for extraction. Since pressure is the main factor that promotes crema formation, a lack of pressure means the coffee will not produce much crema. This is the most common situation, because many friends use the same grind setting throughout their espresso extraction without adjusting it. The condition of the beans changes every day and every hour, and those changes affect the flow rate during extraction. When FrontStreet Coffee used 20g of coffee to extract 40ml of espresso in 32 seconds one day, for example, the next day the same amount of coffee took only 20 seconds to extract 40ml.

Some friends might cleverly add more coffee when the flow is fast and reduce it when the flow is slow. While that is a good option, the capacity of the portafilter basket is ultimately limited. When the condition of the beans changes significantly, even adding more coffee can hardly increase the puck's resistance. Without resistance, the machine will not provide pressure, and rich crema will not form. In such cases, we need to adjust the grind finer. Taking FrontStreet Coffee as an example, the daily morning adjustment first follows a formula: 20g of coffee to extract 40ml of coffee liquid in 28-32 seconds. If the time falls below that range, the grind is adjusted. In the case above, where 20g extracted 40ml in only 20 seconds, the grind needs to be adjusted 2-3 settings finer, then fine-tuned based on taste, with the fine-tuning targeting either liquid weight or coffee amount.

2. Coffee Beans Aren't Fresh Enough

As FrontStreet Coffee mentioned earlier, carbon dioxide is the main component of crema. When beans do not have sufficient carbon dioxide, it is naturally difficult to form rich crema. Generally speaking, the crema extracted from light-roast beans cannot compare with that from dark-roast beans. The freshness of the beans also affects the richness of crema: the fresher the beans, the more carbon dioxide they retain and the richer the crema. As storage time increases, carbon dioxide gradually decreases, and the extracted crema becomes thinner than when the beans were fresh.

Generally, beans within two months of roasting can extract relatively rich crema, provided they are dark-roast beans and stored properly. After two months, the thickness of the extracted crema decreases at a visibly noticeable rate. So we can understand that the freshness of beans affects not only coffee flavor but also the richness of crema.

Finally

Finally, FrontStreet Coffee would like to add one point: espresso crema is essentially a group of bubbles filled with carbon dioxide. Although it is named "crema," which literally means "cream" in Italian, its essence is not the kind of fat we know in daily life. At the same time, more crema is not always better. With proper extraction, the richness of crema is primarily determined by the coffee bean variety and its carbon dioxide content. Neither factor is a key determinant of coffee quality, so crema should not be used as the standard for measuring espresso quality.

FrontStreet Coffee Recommendation

If crema is what you chase, FrontStreet Coffee's classic blends are built to deliver it. The Classic Blend is designed specifically for espresso and the Moka pot, and its greatest strength is outstanding crema: even a beginner on a non-professional home machine can pull dense, fine crema with it. It follows a traditional Mamba recipe for a full, mellow, gentle cup, and it is the blend that makes latte, cappuccino, and Dirty easy to produce at home or in a café.

FrontStreet Coffee's Commercial Blend and the Classic Blend both build on an old-style Italian recipe with a small amount of Robusta added, which is exactly what yields abundant golden crema alongside butter, nut, spice, dark chocolate, and toast aromas — a wild, full body that also makes latte art simple. For a nuttier profile, FrontStreet Coffee's Premium Blend and FrontStreet Coffee's Black Cocoa Blend contain a large proportion of Brazilian coffee, giving a comfortable bittersweet note and a creamy peanut aroma; FrontStreet Coffee's Premium Blend adds Colombian nut, chocolate, and caramel notes with moderate acidity, while FrontStreet Coffee's Black Cocoa Blend pairs Yunnan small beans with Brazilian Cerrado for a balanced cup suited to latte, Americano, and specialty drinks.

Remember that freshness matters for crema: FrontStreet Coffee ships beans roasted within 5 days, with a resting period of about 4-7 days, so your coffee arrives at its peak. For those who prefer single-origin espresso, the Costa Rica Blackberry SOE is a honey-processed bean with high sweetness, and the Brazil Queen's Manor SOE, a rare yellow bourbon, pulls as butter cookie, macadamia, and toast under medium-dark roast, both offering generous crema and their own distinct character.
