Here is a chart that describes the colors of roasted green coffee beans, gives the term we use to describe it in our coffee descriptions, reviews, and articles, and gives you some idea of the taste and aromas that you can expect as your coffee is roasted from light to dark. The temperatures of the coffee bean are taken in a mid-sized artisan commercial roaster. They are not necessarily directly applicable to home green coffee bean roasters because of the batch size and type equipment we use in home roasting. They are provided for informational/trend purposes only.
