What characteristic is associated with dark roast coffees?

Dark roast coffees are characterized by their well-rounded and balanced flavor profile. This is a result of the roasting process, which brings out deeper, more robust flavors by caramelizing the sugars within the coffee beans. The longer roasting time typically leads to a reduction in acidity, resulting in a smoother taste that many find appealing. The balance achieved in dark roasts allows for the presence of bittersweet notes, which can often mask any sharpness or overwhelming acidity that might be found in lighter roasts.

In contrast, the other characteristics described do not align with dark roast coffees. High acidity and crisp flavor are more commonly associated with lighter roasts, which preserve the beans' inherent fruitiness and brightness. A thin and light texture characterizes lighter coffees as well, where the focus is on delicate flavors and body. Lastly, a subtle aroma is generally not a trait of dark roasts; instead, they are known for their strong and bold aromas that reflect the intensity of the roasting process.
