Joule Coffee has opened recently in downtown Raleigh. This is Ashley Christiansen's latest venture and is taking the craft of coffee to its highest level. Every aspect of the coffee drinks are exacting from the temperature of water in the pour over drip coffee to the perfect shot of espresso. I visited many of the nation's top coffee establishments researching the technology and culture of coffee shops. The design of Joule is a riff on a workshop environment, expressing the energy (Joule is a unit of measure of applied energy) of a shop where things are made precisely.
