Some friends may know about coffee beans, but not know that coffee beans are also divided into espresso and single-origin. Actually, it's not hard to understand. The lattes we often drink belong to espresso coffee, and the coffee beans used must correspond accordingly—not all coffee beans can be used to make espresso. Some people ask Front Street Coffee: What kind of coffee beans can be used to make espresso? And how should single-origin coffee beans be understood?


Listen to what Front Street Coffee says, and perhaps you will understand.

 

So-called espresso coffee beans refer to coffee beans used to make espresso. The steam pressure extraction machine was invented by Italians. The espresso made by a steam pressure coffee machine is espresso. For example, lattes and cappuccinos are all based on Espresso, then combined with milk or sugar and other ingredients. Espresso is made with an espresso machine, so coffee made with Espresso as the base is often called espresso coffee. The beans used to make Espresso are mostly blended from several coffee beans from different origins in certain proportions. This kind of coffee bean is also called blended coffee beans. Of course, now there are also espresso made from single-origin coffee beans, such as Single Original Espresso, SOE.

Blended beans generally use medium-dark roasting. For blended beans, sometimes the beans are mixed first and then roasted, which is called raw blending; sometimes the coffee beans are roasted first and then mixed, which is called roasted blending. Whether raw blending or roasted blending, before blending the beans, you must first know what flavors different varieties of coffee have, and that coffee beans from different origins have different characteristics. Different coffee beans have different personalities due to different varieties and origins, with subtle differences in acidity, bitterness, sweetness, aroma, body, and other flavors. In order to create a better blend, the roaster must not only know the characteristics of the coffee beans thoroughly, but also master superb roasting skills, so creating a good blend is still very difficult.

 

Since coffee beans are a crop, even the same kind of coffee bean will have different flavors each year. Therefore, Front Street Coffee believes that mixing several coffee beans together solves this problem well, allowing the taste to remain basically consistent every year. At the same time, it also requires being a major coffee-producing country, so that the demand for coffee beans can be guaranteed.

According to the producing country, region, and type of coffee beans, espresso coffee beans can be divided into three types: Arabica + Robusta blends, 100% Arabica blends, and single-origin espresso SOE.

 

Arabica + Robusta blend: Adding Robusta beans during blending can improve body, enrich crema, and reduce cost. Therefore, this blending method is very common and mainstream.

100% Arabica blend: Generally speaking, Arabica is a better variety than Robusta, with a more elegant flavor spectrum and more complex flavors, so a 100% Arabica blend is theoretically better in flavor and higher in price. However, we cannot simply judge the superiority of beans by bean variety, because there are too many factors affecting coffee beans (producing country, region, processing method, roasting, etc.), so naturally there are also poor Arabica beans and good Robusta beans.
