What is a characteristic of Arabica coffee beans?

Arabica coffee beans are renowned for their sweeter aroma and flavor, which is due to their chemical composition. They contain a higher level of sugars and a more complex flavor profile compared to other varieties, particularly Robusta. This sweetness is often accompanied by a variety of taste notes that can include fruit, floral, and nutty hints, contributing to a more nuanced tasting experience.

In contrast, the higher caffeine content associated with Robusta beans makes option A inaccurate, as Arabica beans actually have less caffeine. Additionally, the shape of Arabica beans, which are oval and have a curved slit, differs from the rounder shape of Robusta beans, making option C misleading. Lastly, Arabica plants thrive better at higher altitudes, typically between 2,000 to 6,000 feet, rather than low altitudes, which makes option D incorrect. This preference for altitude is linked to the cooler temperatures and increased rainfall found in these regions, which contribute to the development of the beans' flavors.
