I'm a bit of a coffee nut myself. Own a roastery and mobile espresso van. Light roasts are my favorite. Not only do they have more character but they also contain more caffeine. Ethiopian Yirgacheffe roasted to city+ is my favorite, but I've been digging this Costa Rican Tarrazu roasted to full city as well. I roast in a Diedrich IR12, its a 25lb roaster with infrared burners and a sealed drum.Light roasts rock. The Beloya I'm drinking is a light roast (City) What a lot of people don't realize is that the darker you roast, the more you lose characteristics of Single Origin beans. Do you want to taste the bean or the roast? Personally I'd rather taste the bean. Quite often I have heard people say light roasts are weak, but they don't have a clue. If one really want to experience the flavors that a bean has to offer, don't over-roast. I, as well as many others, consider it undesirable for the roast characteristics to be more prominent than that of the beans themselves.
