16. Founders Brewing Co.
Location: Grand Rapids, Michigan
Year Established: 1997
Because they make one of the most sought-after limited-release beers in the country (KBS, a bourbon-barrel aged breakfast stout), Founders has become one very buzzy brewery. The same craft that goes into KBS also goes into the brewery's other year-round and seasonal beers. Some of the best examples available include their Centennial IPA and the All-Day IPA, a sessionable (or low-alcohol) brew.
