What type of coffee roast typically has the darkest flavor profile?

The dark roast is known for its rich and bold flavor profile, which is achieved by roasting the coffee beans for a longer period. During this process, the beans reach a higher temperature which not only develops deeper flavors but also creates a characteristic oiliness on the surface. This roasting style often brings out notes like bittersweet chocolate, smoky undertones, and sometimes a slight char.

In contrast, light and blonde roasts retain more of the original characteristics of the coffee bean, highlighting the acidity and fruitiness rather than a deeper, darker flavor. Medium roasts provide a balance between the brightness of light roasts and the deeper flavors of dark roasts, but they still do not achieve the same level of robust flavor that dark roasts are known for. Thus, when considering the options, it is clear that the dark roast is the one that offers the darkest and most intense flavor profile among them.
