Which statement describes the development phase in coffee roasting?

• A. The coffee beans must be cooled quickly
• B. The beans begin to change color and develop flavor
• C. The beans are ground to release flavors
• D. The roasting session is concluded

Answer: (B)

The development phase in coffee roasting is characterized by significant changes in the coffee beans, particularly in terms of color and flavor. During this stage, the beans transition from their raw, green state to a roasted state, changing color from green to yellow, and eventually to brown as the roasting progresses. This is also when the complex flavors characteristic of coffee begin to develop due to the Maillard reaction and caramelization of sugars.

As the beans continue to roast during this phase, the development of oils and other aromatic compounds enhances the flavor profile. This phase is critical because it influences the final taste of the coffee; therefore, roasters pay close attention to timing and temperature to optimize flavor development. Understanding this phase is fundamental for producing coffee with the desired flavor characteristics.
