Boiling Point of Caffeine - Coffee Fact

Caffeine has a boiling point of 178 C and this is a very common temperature reached by roasters, even for light roasts. However caffeine is still considered moleculary stable till temperatures of 235 C which is rarely reached let alone by the inner layers of the bean where the caffeine resides. With that being said, if the caffeine is stable then the argument of whether darker or lighter roasts have more caffeine should be settled with this: “There is no difference, and if there is then it is a negligible difference”.
