                                According to the FDA, decaffeinated coffee must have at least 97% of its caffeine removed, meaning trace amounts always remain. This fact applies directly to Dunkin Donuts decaf, which is not completely caffeine-free, despite what the name suggests. It is important to understand what is truly in your cup.
