What is a key characteristic of dark roast coffee flavors?

Dark roast coffee is characterized by its smoky or bitter notes, resulting from the longer roasting process, which raises the coffee beans' internal temperature and leads to the development of certain flavor compounds. During this process, the natural sugars within the beans caramelize and begin to break down, creating complex flavors that include a pronounced bitterness and a deep, smoky taste.

These flavors often mask some of the lighter, more delicate qualities that are found in lighter roast coffees, such as acidity and floral notes. Consequently, dark roast coffees tend to have less brightness and acidity, focusing more on rich, bold flavors. This is why when identifying a key characteristic of dark roast coffee flavors, smoky or bitter notes are integral to its profile. Such notes are often desired by those who enjoy a more intense coffee experience.
