9. Deschutes Brewing
2012 production: 253,000 barrels
A member of the fabled "Class of '88" that included Fort Bragg, Calif.'s North Coast, Chicago's Goose Island, Cleveland's Great Lakes and Deschutes' Oregon neighbor Rogue Ales, Deschutes has grown into the largest of all of them -- at least the ones not owned by A-B. It's still growing, opening a brewpub and small-batch brewhouse in Portland's Pearl District in 2008 and adding an extra 105,000 barrels of production capacity to its Bend facility just last year. Though Deschutes still distributes to only 21 states -- and in Philadelphia only on the East Coast -- founder Gary Fish clearly has bigger plans for his Black Butte Porter, Mirror Pond Pale Ale, Inversion IPA and Jubelale.
