Erroneous Urban Coffee Legends and stuff

Erroneous urban coffee legend #1 There is less caffeine in a dark roast than a medium roast. The answer to this question can be found by asking yourself another question "What is the sublimation temperature of caffeine?" The answer is 459.3 degrees F. This my friends is very, very dark and a highly unpalatable roast level.I have only one coffee I roast to this temperature and it is done only for those customers who enjoy this level of dark roast. The answer to the caffeine content is also impacted by the coffee varietal which helps to cloud the concept further as different hybrids have differing levels of caffeine content. To those wishing a tasty decaf coffee they are in the process of genetically engineering a coffee to be decaffeinated with the hopes of maintaining it's varietal flavor characteristics.
