What does the term "flavor" refer to in coffee?

In the context of coffee, "flavor" specifically relates to how a coffee tastes, capturing the complex combination of tastes and aromatic sensations derived from the coffee beans. It encompasses various elements, including sweetness, acidity, bitterness, and the presence of specific notes such as fruity, floral, nutty, or chocolatey characteristics. Understanding flavor is essential for coffee enthusiasts and professionals, as it plays a crucial role in tasting and evaluating different coffee varieties.

While the other options address relevant aspects of coffee, they do not define "flavor." Brewing methods can influence flavor but do not encompass the term itself. Similarly, serving temperature can affect the perception of flavor but is not synonymous with it, and caffeine content relates to the stimulant effect of coffee rather than its taste profile. Thus, option B provides the most accurate understanding of the term "flavor" in relation to coffee.
