What typically characterizes a light roast coffee?

A light roast coffee is characterized by its lighter color, which occurs because it is roasted for a shorter amount of time compared to darker roasts. This roasting method preserves the coffee beans' original characteristics, leading to a taste profile that often includes higher acidity levels and distinct floral flavors. The brightness of the acidity is balanced with the complexities of the bean's inherent notes, often bringing out nuanced flavors that can be described as fruity or floral.

The other choices reflect characteristics of different roast levels. Dark brown with low acidity and chocolate flavors typically describe a medium to dark roast, where the roasting process has begun to alter the natural flavors of the bean significantly. A rich and oily texture with nutty flavors is often seen in medium and dark roasts, where oils are released from the beans during a longer roasting period. Finally, slightly burnt with smoky flavors indicates an over-roasted coffee, which masks the natural characteristics of the beans in favor of more charred and bitter notes. Therefore, option A accurately defines the distinctive qualities of light roast coffee.
