While brackets for college basketball are being hastily filled in, we've decided to put together our own bracket. We're pitting the top 64 brewers on Untappd based on user check-ins against each other. Which brewery will come out on top? It's up to you to decide.

During each round of that other bracket, we will track check-ins to beers from each brewery. At the end of the round, the brewery with the most check-ins will move on, until we end up with the Brewery Madness champion. Want your favorite brewery to win? Just check-in during the round dates listed to help it advance toward victory! The winning brewery will get their own special Brewery Madness badge for all of their fans to unlock.
