Or would highly recommend? It was only partially about beer, but I just got done watching prohibition by Ken burns and it was pretty awesome and informative.
I really enjoyed American Beer. You would have to buy it through Amazon or something. It is not new, but very cool. Five guys from NY that travel the country going to breweries. I think 38 in 40 days.
I thought it was great (since I know several of the people being profiled). http://sudscountyusa.com/
I hated that movie. I did, however, like the beer episode of "The Works", and Beer Nation! Not sure if you could call Beer Nation a documentary, though...
