I was originally planning to give a lecture, but organizers from the Center for the Advancement of Teaching and Scholarship (CARS) asked me to present my work as a poster, and offered to cover the cost of a tea tasting as part of the conference's closing reception. My poster is available as a PowerPoint file (which includes details of the seven Teavana teas I served), but one slide in particular seems appropriate for this blog. As I thought about the geographies of these two beverages, I realized that I was forming lists of the commonalities and distinctions that might best be described using a Venn diagram. The result, I think, is a reasonable starting point for discussing these two globally important beverages.
