Folgers, a well known coffee manufacturer, offers a coffee named Simply Smooth that is specially blended and roasted to reduce certain irritants that are associated with stomach discomfort. Simply Smooth coffee has received multiple superior reviews from users on the Folgers site.
According to an article on WebMD, the process of roasting coffee beans is what brings out the chemical compounds that cause increased acid production in the stomach. However, some of the new, smoother coffee blends produced by certain manufacturers are made by steaming raw coffee beans. This process prevents the irritating chemical compound from becoming active in the coffee beans themselves. The only negative aspect to the steaming process in contrast to the original roasting process is that scientists have found that the former reduces the amount of healthful substances in coffee that can decrease diabetes and heart disease.
