Book excerpt: Drift is all about coffee. It's about the people who drink it and the cities they inhabit, from consumers to coffeehouse owners to street venders to baristas. It's about the ways coffee helps us chart the geography of our environment. Each issue, Drift brings you a glimpse of what it's like to drink coffee in a different city. It highlights locals and visitors both, and explores what makes them tick. Drift Volume 5 focuses on Melbourne, an unlikely frontrunner for the most influential coffee city on earth.
