I am a huge drinker of dark roast coffee. I have had every brand that sells dark roast. I discovered-to my surprise-a dark roast coffee at Aroma cafes. It is an authentic very flavourful coffee that leaves no heartburn or after taste; something I have experience in other brands. You must ask for it-it is not prepared in advance and they will grind the beans fresh for you. The process takes 5-6 minutes but so worth it. It is a dark roast that is not over-powering and the caffeine level is very low. Worth the effort to find this café(s) as this is not sold in stores.
