This reaction is known as the Maillard Reaction, and it occurs in nearly every cooking. The result is that the smell of coffee that has been roasted is a reflection of those chemical compounds. While the Maillard Reaction affects the overall flavor of the roast, nonvolatile as well as volatile compounds also contribute to the flavor of a coffee. Unroasted or green beans can be a bit sweet, floral or earthy. Bitterness is typically related to roasts that are full-bodied and contain more caffeine, however it can also be due to poor brewing methods or storage. Flavored coffee beans have flavor oils that help preserve the beans and give them a distinct scent and taste. The flavored oils are a combination of natural and chemical flavors that range from vanilla to cinnamon to chocolate. The flavors attach to the beans through a chemical compound that is called polyphenol.
