Espresso Basics: What is Crema
During the roasting process, coffee beans generate large amounts of carbon dioxide. Most of this gas dissipates during cooling, while a small amount remains trapped within the beans. Grinding releases these gases, which is why coffee must be prepared as quickly as possible after grinding. When hot water impacts coffee grounds under high pressure, it emulsifies the insoluble oils from the coffee grounds

This is because the soluble substances in coffee are completely dissolved in water after one extraction process. Any subsequent brewing attempts will yield nothing but continued steeping of the woody fibers in the coffee beans.

What Products are Generated by the Caramelization Reaction During Roasting? What Happens When Caramelization is Excessive or Insufficient?
Professional coffee knowledge exchange. For more coffee bean information, please follow Coffee Workshop (WeChat official account: cafe_style). FrontStreet Coffee briefly explains the caramelization reaction during roasting. The sugars in coffee beans undergo caramelization reaction at approximately 170-200°C, which coincides with the melting point of sucrose (185°C) and the temperature range during the first crack phase of coffee bean roasting. The products of the caramelization reaction include various compounds that contribute to the aroma, flavor, and color development in coffee beans. When caramelization is insufficient, the coffee may lack sweetness and complexity, while excessive caramelization can lead to bitter, burnt flavors that mask the coffee's inherent characteristics.
