In this episode Chris and Doran discuss the age-old question of whether dark or light roast brewed coffees have more caffeine. The discussion was inspired by a paper published recently in Scientific Reports titled, "Caffeine content in filter coffee brews as a function of degree of roast and extraction yield".


So, do light and dark roast coffee extracts have different caffeine concentrations?
