Many coffee enthusiasts, while enjoying an espresso, notice black particles settling at the bottom of the cup and worry whether this means something went wrong with the extraction.

The same coffee beans can present completely different flavors depending on the extraction method. Take Front Street Indonesia Mandheling, a medium-dark roast, as an example: when brewed as pour-over, it is mellow and gentle, with notes of caramel, herbs, and spices; if instead made into espresso with a coffee machine, it develops a rich layer of crema, releasing layers of dark chocolate, cream, and roasted nut aromas, and when drunk straight it is intense and stimulating with a pronounced roasted note. This shows that choosing coffee beans cannot be done casually; you need to consider the extraction method, roast level, and freshness. Fresh beans are rich in carbon dioxide, and together with the porous structure of a dark roast, they make it easier to extract a large amount of crema and roasting aromas such as chocolate, cocoa, butter, cookies, and caramel. For beginners, value for money is especially important. Below are five of the most popular espresso blends, covering Front Street Specialty Blend, Commercial Blend, Dark Cocoa Blend, and Classic Blend, along with their respective suitable scenarios and flavor characteristics, for reference whether for opening a shop or home use.
