Which of the following is a common characteristic of medium roast coffee?

Medium roast coffee is known for its balanced flavor profile, which is one of its most distinguishing characteristics. This roast level typically achieves a harmonious meld of the inherent flavors of the coffee bean and the roasting process itself. This balance allows the natural sweetness and acidity to emerge without overwhelming bitterness, making it appealing to a wide variety of coffee drinkers.

When coffee beans are roasted to a medium level, they develop a roundness in flavor that often includes a mix of fruity, nutty, and chocolaty notes, providing a well-rounded taste experience. This balance is key in attracting customers who prefer a milder coffee that doesn't lean too heavily on any one flavor characteristic, making medium roast a popular choice in coffee shops.

In contrast, high acidity is typically associated with light roasts, and strong bitterness is more frequently found in dark roasts. A light body is characteristic of lighter roasts as well; medium roasts usually have a fuller body compared to their lighter counterparts. Thus, the presence of a balanced flavor is what clearly identifies medium roast coffee among the choices provided.
