(MercuryNews) - The annual Wine Road Barrel Tasting may be uncorking a little too much rowdiness for the town in the center of it all. Some Healdsburg merchants are complaining that younger imbibers are getting carried away, transforming the event into a "frat party," a "beer blaster." On back-to-back weekends this month, merchants said, they witnessed participants stagger from one tasting room to another, hanging on benches and even getting sick from too much alcohol. "There's incredible drunkenness," Anne Marie Montecuollo, owner of a fine jewelry store, told the City Council Monday.
