It costs more these days. But yeah, so does everything. What makes coffee a perfect product to explore the world's rising costs, though, is its ubiquity. You can get it absolutely anywhere in the world—but not only that, dozens upon dozens of countries grow, produce and export it, so no one factor in one nation or on one continent explains why your latte costs more.

So how does the coffee industry work? Why and how is it changing? And what can that tell us about ... everything else?
