Franklin Street is pushing the conversation. West O makes really competent beer but hasn't done anything new. Madhouse has amazing sours and big stouts, but neglects regular styles. Will be interesting to see how TG's expansion goes. If they close the College Drive location, they will be relying on weekends and beer tourism for taproom sales. Pulpit has surpassed TG for me, and I don't see that changing with the current trajectory. Their beers and focus are more my style, it's run by better people, and the location is a winner. TG makes really damn good beer, and having Iowa brewed Sue cans will be awesome.
Look out for Pivo in Calmar, next year. They opened Thanksgiving week and hit the ground running with some really solid beer right out the gate. Solid facility, and a good model.
