So, how exactly is flavor added?
Well, the flavor is added in almost all cases after the beans have been roasted, but in some cases if you buy a gourmet coffee the flavorings are put in after it has already been cooked and is ready to drink. Never the less they can be chemically reproduced or real flavorings such as all natural vanilla beans, or extract, or real cinnamon. It really depends upon the gourmet coffee company you choose and their practice, but since those chemicals are rarely good for you, you may go out of your way to look for an organic alternative. In most cases the freshly harvested and then roasted beans are simply coated in flavor compounds to still give you the original taste of the gourmet coffee.
