Some people drink espresso and like the flavor, and some people drink espresso and like the texture. Those who like flavor have a variety of SOE coffee beans to choose from, but those who like a richer taste have what coffee beans to choose from?
The signature feature of espresso - Crema
The most fascinating thing about espresso is the delicate golden layercoffee crema, Italians call it Crema. The formation of this layer of grease is due to the high-pressure extraction of the espresso machine, which causes the grease to flow into the cup surrounded by carbon dioxide. And because the carbon dioxide wrapped in grease cannot evaporate for a while, it forms a temporarily stable structure.

coffee cremaThe thickness and color also represent the quality of espresso. For a qualified cup of espresso, the oil thickness should be 1/3 of the coffee liquid, the color should be golden yellow, and the surface should be smooth and delicate without large bubbles.
What are the factors that affect coffee oil?
①Freshness of coffee beans
Because the oil is produced by the oil in the coffee wrapping the carbon dioxide in the coffee, you can also judge whether the coffee beans are fresh by the amount of oil. The more oil, the fresher the coffee beans.
②Roasting degree of coffee beans
Similarly, under the same conditions of freshness and more oil, we can also think that the beans are roasted darker.
③Extraction degree of coffee beans
The darker the oil, the more dissolved substances in the coffee have entered the coffee liquid.

④Variety of coffee beans
Different coffee species will produce different characteristics, which will also affect the amount of oil produced. It is currently known that Robusta coffee species produce more oil than Arabica coffee species.
Any recommendations for coffee beans that are rich in oil?
We all know that Arabica has a sweet flavor, while Robusta has a burnt, bitter and woody flavor, but Robusta is richer in oil than Arabica. All Italians who like a richer taste are accustomed to using Arabica coffee beans with a little Robusta coffee beans.

For customers who like fat and texture, Front Street has formulated a Front Street Italian blend of coffee beans, named "Front Street Commercial Blend Coffee Beans", which is a blend of Arabica coffee beans from Brazil and Colombia and 10% Robusta coffee beans. This Front Street commercial bean blend tastes rich in oil and texture, with the sweetness of caramel, and also has the flavor of nuts, cocoa, and dark chocolate. It has a balance of sweet and sour, a little bit of sweetness and bitterness, and a long-lasting aftertaste. Adding a small amount of Robusta coffee beans adds richness to the oil, and since the amount is small, it does not change the flavor too much.
The reason why Front Street named this blended coffee bean "Front Street Commercial Blend Coffee Bean" is because it performs well in making American-style or milk coffee. With its price advantage, it is very suitable for use in commercial cafes.
Rich oil makes latte art better
Espresso is also the base for making latte coffee, and hot latte is often accompanied by exquisite latte patterns. The delicate and rich coffee oil makes it easier to draw flowers.
Espresso coffee with oil can better integrate with milk foam and maintain a stable state, which has a great influence on the detail and shape of latte art. Although espresso coffee without oil can also be latte art, the drawn pattern will be slightly stiff and rough in appearance.

Besides coffee beans, what is the main cause of oil thinning?
The barista of FrontStreet Coffee just shared several factors that affect the oil. But after ruling out several factors, what is the reason why the oil of espresso is thin and dilute? We believe that the problem still lies in pressure. Looking back at the concept of grease just shared, grease is a product of a stressful environment. With enough pressure, even lightly roasted coffee beans can extract some oil.
If consumers cannot extract the ideal oil state when extracting blended beans specifically for espresso, then the barista at FrontStreet Coffee will recommend that you check the extraction pressure, or upgrade to an espresso machine with commercial capabilities.
