The golden foam on the surface of espresso is often called the "soul" of coffee, but when tasted on its own, that intense bitterness often catches people off guard—it can even be more bitter than the coffee liquid itself.

Front Street Coffee previously conducted a dedicated comparative experiment, confirming that the bitterness of Americano with the oils removed is indeed noticeably lower. That being the case, where exactly does the bitterness of this layer of oils come from? And why does it still keep so many enthusiasts coming back for more? This article will examine extraction principles, the causes of bitterness, and aroma, mouthfeel, and finish, among other dimensions, to help you reunderstand espresso's crema and offer better ideas for drinking it.

The final expression of a cup of coffee is the result of the combined effects of origin, variety, processing method, roasting, and brewing, among which the roast level directly affects the balance of acidity and bitterness as well as the flavor direction. In the context of espresso, the three roast levels—light, medium, and dark—bring about distinctly different extraction performances: light-roasted beans retain more origin flavors and organic acids, but are difficult to extract and produce thin crema; medium-roasted beans balance acidity and bitterness, making them suitable for those seeking a harmonious taste; dark-roasted beans, with their high body and rich crema, become the ideal choice for espresso. This article takes several Front Street Coffee beans as examples, using actual extraction parameters and flavor descriptions to systematically analyze the differences in how various roast levels perform in espresso, and explains the principle behind why blended coffee has richer crema.

When you order an Americano at a coffee shop, a golden layer of crema often floats on the surface, and most people don't pay it much attention. But through comparative experiments, Front Street Coffee found that if you use a spoon to skim off this layer of crema, the bitterness of the Americano is noticeably reduced, and the flavor becomes cleaner and more transparent. The reason behind this is closely tied to the composition of the crema: it consists of carbon dioxide and insoluble oils, mixed with extremely fine particles that fall off during extraction, and these fine particles are the very source of the muddled mouthfeel and sandy texture. However, coffee shops usually don't actively remove the crema, due to multiple considerations such as serving efficiency, customer perceptual habits, and differences in taste preferences. This article will analyze in detail the real impact of crema on Americano coffee, and introduce how Front Street Coffee's classic blend helps beginners easily extract a rich crema at home and make their ideal Americano.
