"Starbucks coffee doesn't taste like it is roasted, it tastes like it has been burnt" When you roast coffee as dark as they do, the taste is mainly carbon, not the underlying coffee. The Sweet Marias site sells green coffee to people who want to roast their own, there is a fair amount of information on home roasting, e.g., http://www.sweetmarias.com/roastedcoffee_grindVSsurfacecolor.html
