Making BAD decisions since 2011! BAD Brewing Company BAD Brewing Company is a small Microbrewery located in downtown Mason, MI that opened in the Summer of 2012. We will offer a wide selection of hand crafted beers. We will have at least five house beers on tap, with several more on a rotating basis. All of the beers are hand crafted on site by the owner, and new recipes are always in the works! BAD Brewing looks forward to serving Mason and the Greater Lansing area the finest hand crafted beers possible. Have a BAD day! Like us on Facebook!
