An Analysis of the Pros and Cons of Natural Process Coffee Beans: Flavor Characteristics, Processing Risks, and Price Factors

Where Does Espresso Crema Come From? Key Factors Affecting Crema Thickness and Espresso Bean Recommendations

The golden to chocolate-colored layer of foam on the surface of espresso is what is commonly called crema. It is not only a visual hallmark, but also affects the flavor and mouthfeel of the coffee. Crema is essentially a fine bubble mixture formed when water extracts coffee grounds under high temperature and high pressure, emulsifying natural fats and oils and trapping air and carbon dioxide. Its amount is closely related to coffee variety, roast date, roast level, and extraction equipment: Robusta produces a thick crema, while Arabica tends toward fruity acidity and a moderate mouthfeel; freshly roasted coffee can enhance emulsification, but coffee that is too fresh or too old will throw the crema out of balance; dark roasts produce a thicker, more viscous crema, while roasting too dark backfires. In this article, Front Street will break down these variables one by one and recommend several espresso beans suitable for those pursuing a rich crema. [more…]
