Two new businesses slated to open in Sonoma Valley will expand the artisan beer experience available in wine country.  Soon to open in Fiesta Plaza in the Springs is the Olde Sonoma Public House, with local owners Coley and Jo Thinnes and Ron Dardis, offering more than 20 beers on tap in a warm and inviting environment.  Local resident Dean Biersch will be opening Sonoma Hopmonk Tavern on Broadway later this summer (more details are available in a recent article in the Sonoma Index-Tribune).  These new additions join the bavarian-style offerings at Sonoma Springs Brewing Co. (750 W. Napa St.), the "American Beer Garden" at Mondo, and the German beers that accompany "European Soul Food" at Lokal, all of which have opened their doors within the past couple of years.
