Many manufacturers of prepackaged coffees have several different blends available. However, there are three main levels of roasting coffee beans. These three levels are light roast, medium roast, and dark roast. The names of the different roasts reflect the color of the beans, which is indicative of how long the beans have been roasted. Light roast coffee beans have been roasted the least amount of time, which makes them much lighter in color. Dark roast coffee beans have been roasted for a much longer time which gives them a darker appearance. Dark roasts are also more caffeinated than other roasts.
