The Geography of Beer

The Geography of Beer, published by Springer. Matt Zook and his research partner, Ate Poorthuis analyzed almost a million “geocoded beer tweets” produced between 2012 and 2013 that were drawn from a larger database known as DOLLY, a university of Kentucky project that houses billions of location-based tweets, to determine what beer brands get discussed on social media all across the United States.

One of several Beer Maps produced by the project.  It's worth noting that applications for admission to the Geography Department at UK have quadrupled (although 32% of the applicants show up late or not at all for the interview)
