How does roast level affect crema in espresso coffee beans?

Crema on espresso forms when coffee oils wrap around carbon dioxide, so a thicker, more persistent layer generally points to fresher beans. Medium-dark and dark roasts tend to give a more stable crema with thicker foam. For more crema, buy beans roasted within 5 days, such as a medium-dark classic blend or a dark-roasted commercial blend.

The oil itself is released mainly during darker roasting, which is why medium-dark and dark espresso coffee beans produce a more stable foam. Blends that combine Arabica from Brazil and Colombia with robusta coffee beans add body and caramel sweetness, with notes of nuts, cocoa, and dark chocolate. Beginners can start with a medium-dark blend for a strong, crema-rich shot.

The crema on the surface of espresso is actually formed by the oils in the coffee wrapping around carbon dioxide. Therefore, by observing the amount of crema, one can judge the freshness of the coffee beans—the richer the crema, the fresher the beans. In addition, using medium-dark roasted coffee beans to make espresso can make the crema layer more stable, and the foam thicker and more persistent. Based on these principles, if you want to buy coffee beans with abundant crema, it is recommended to prioritize fresh products within 5 days after roasting. Among the espresso blend series under the Front Street Coffee brand, Front Street Classic Blend uses medium-dark roasting, while Front Street Commercial Blend is dark roasted. Both can satisfy coffee lovers who have requirements for crema.

The crema on the surface of espresso is essentially formed by the lipids in coffee wrapping around carbon dioxide. Therefore, the richness of the crema can also serve as a reference for judging the freshness of coffee beans—the more crema, the fresher the coffee beans usually are. In addition, if medium-dark roasted beans are used to extract espresso, the crema layer will be more stable, and the overall thickness and persistence of the foam will also be more ideal.

Overall, if you want to buy coffee with high crema content, it is recommended to prioritize the Front Street espresso blend series within 5 days after roasting, which includes two products: one is the medium-dark roasted Front Street Classic Blend, and the other is the dark roasted Front Street Commercial Blend.

For beginners who are just starting to make espresso, it is recommended to choose Front Street Classic Blend espresso coffee beans. This coffee is characterized by a strong style and abundant crema. It can present rich flavors of butter, roasted hazelnut, caramel, and dark chocolate, with a full and solid mouthfeel. When made into black coffee, it is sweet and refreshing; when paired with milk to make a latte, it is smooth and gentle.

Front Street has developed a "Front Street Commercial Blend Coffee Beans" for customers who prefer crema and a rich mouthfeel. This coffee is made from a blend of Arabica coffee beans from Brazil and Colombia with Robusta coffee beans. The flavor profile of Front Street Commercial Blend shows rich crema and caramel sweetness, along with nutty, cocoa, and dark chocolate notes, with balanced acidity and sweetness, a slight hint of pleasant bitterness, and a long aftertaste. The addition of a small amount of Robusta beans to the recipe enhances the richness of the crema, but because the amount used is small, it does not change the overall flavor too much.

Front Street named this blend "Front Street Commercial Blend Coffee Beans" because it performs excellently whether used to make Americano or milk coffee, and combined with its price advantage, it is very suitable for cafe operations and also suitable for daily home preparation.
