Dark roasted coffees are dark brown in color, like chocolate, or sometimes almost black. They have a sheen of oil on the surface, which is usually evident in the cup when the dark roast coffee is brewed. The coffee’s origin flavors are eclipsed by the flavors of the roasting process. The coffee will generally have a bitter and smoky or even burnt taste. The amount of caffeine is substantially decreased.
This can taste like cowboy coffee: dark, rich, stewy. Sumatrans are great in this roast range. It’s an industry secret that when you have beans you’re trying to use up rather than putting them on sale you put them into a French Roast. Almost anything tastes alike in a French Roast...(We don't do that here however.)
Dark roasts go by many names. As a result, buying a dark roast can be confusing. Some of the more popular designations for a dark roast include French Roast, Italian Roast, Espresso Roast, Continental Roast, New Orleans Roast, and Spanish Roast. Many dark roasts are used for espresso blends.
