Beerviz has a neat-o interactive chart that helps serious beer drinkers figure out what kind of beer they should try next based on their tastes. Prepare to have your horizons broadened, drunks!
The thing is really easy to use. Just select what kind of beer you like to drink—light, medium, or dark—and the chart populates with all kinds of beers fitting that description. Mouse over the ones you like to see what suggested beers the lines lead you to. All of the data is based on beer reviews from Beer Advocate.
