What characteristic is associated with 'light roasts' in coffee?

• A. They have a more bitter flavor
• B. They contain less caffeine than darker roasts
• C. They exhibit brighter acidity and retain more original bean flavors
• D. They are darker in color and richer in flavor

Answer: (C)

Light roasts are recognized for their distinct characteristics, particularly their bright acidity and the preservation of the original flavors inherent in the coffee beans. During the roasting process, lighter roasts maintain the unique traits of the coffee origins, such as fruity, floral, and other nuanced flavors that might be overshadowed in darker roasts.

This vibrant acidity is often described as a lively, tangy quality, which is a hallmark of light roasts. They typically show more clarity and a complex flavor profile, allowing coffee drinkers to experience the varying notes that different bean varieties offer.

In contrast, as the roast level increases, the flavors shift towards deeper, more robust profiles; thus, darker roasts tend to lose the distinct characteristics of the original beans in favor of more uniform flavors that can include bittersweet chocolate or caramel. This is important for understanding how roasting levels influence the sensory experience of coffee.
