9. Two Brothers Brewing Co.
Location: Warrenville, Illinois
Year Established: 1996
The name of this brewery tells much of the story-it was founded by two brothers back in 1996 and they've been crafting incredible beer ever since. Even before Goose Island went corporate, Two Brothers was considered the standout small brewery in Illinois. They're only available in a handful of states now, but their reach continues to spread to new places. The beers recently returned to shelves in Pennsylvania (after a two year hiatus) and their 2013 collaboration with Aleman and Stone Brewing, DayMan Coffee IPA, gave them a chance to see the west coast.
