As of May 2012, homebrewers in the North Bay have a retail shop to grab their goods. J&M Brewing Supplies opened up on Roblar Drive in that small strip of businesses just north of Hamilton Marketplace and just south of Bel Marin Keys Boulevard.
Joe Capone, who works at Biomarin, opened the place with Grammy Award-winning sound engineer Marty Wall as a source for homebrewers as well as people who want to make wine and cheese. J&M is a site for homebrewing classes and other DIY seminars, too.
