I ran across this post yesterday over on BeerAdvocate. Custom label manufacturer, Etiquette Systems, has posted a map of the U.S. created from images of beer labels. By clicking on a state you can see a larger image of the selected beer label. For those with non-Flash enabled computers, there's an image-only version here.
The post on BeerAdvocate generated the usual BA ramblings of the wrong beers being chosen for some states. However, I thought this was is an interesting project and it certainly helps illustrates the spread of breweries across the U.S. I enjoyed clicking through the map and seeing what beers were chosen for each state.
