If you are a fan of espresso and Starbucks coffee, you most likely enjoy dark coffee roasts.  These coffee beans are roasted the longest of all bean roasts until they are the color of dark chocolate. The long roast time brings out the bean’s oil which you can see in the brew and produces a strong, sometimes bitter taste.  Dark roasts feature an extra bold body and heavy mouthfeel that is preferred by many coffee lovers, especially those in Europe.
