When choosing how light or dark to roast a coffee, we must take into account its origin, its processing, and finally what flavors we want to showcase. At a very basic level, a light roast will allow the coffee to sing its own song, a medium roast will balance the coffee’s inherent flavors with the Maillard reaction’s caramelization and sugar development, while dark roasts give the roaster more influence, imparting those recognizably smoky, dark chocolate notes.
