I found a good article at Coffeenerds.com on how coffee flavorings are added to our favored coffees. I thought you may be interested to know how it is done. I agree with the author of this article though in terms of adding flavor to a perfectly roasted bean. If it is a quality bean, roasted properly, and brewed right, there is no reason to add flavoring before it makes it to the consumer. Add it afterwards if you’d like but why mess up a fantastic cup of coffee?
Here is the link to How Does One Flavor Their Coffee Beans? I hope you enjoy it. I know I did.
