Because the roasting process is what reveals a coffee bean’s unique characteristics “care” is the essential word for roasting craft coffee. There are three basic roasting categories: light, medium, and dark.
Light roasts retain most of the original characteristics of a coffee bean (as well as its caffeine content), but can be a bit more acidic.
Acidity begins to drop, while most characteristics are preserved.
Typically considered the smoothest roasts, though they can lose some flavor complexity.
Ever have a cup of coffee that tastes burned? Roasters that get so large that they have to supply enormous quantities of coffee beans ensure consistency by over-roasting their various beans, which destroys a lot of their subtle characteristics. Don’t drink that.
