20. Surly Brewing Co.
Location: Brooklyn Center, Minnesota
Year Established: 1994
They're small and located in a town you've probably never heard of but Surly is growing and their aggressive canned beers deserve all the attention they get. Furious, a highly hopped American IPA, is just the start. These brewers have crafted an impressive list of beers that many die-hard beer drinkers have grown to love.
