DeLoach Vineyards was prepared Saturday for the opening weekend of the 35th annual Wine Road Barrel Tasting event. Photo Galleries The smell of Chicago-style hot dogs wafted across the entrance to the Olivet Road facility. Inside the cellar, Boston's “More than a Feeling” blasted on a stereo as about a dozen imbibers enjoyed wines directly from barrels. The only thing missing? Hordes of inebriated customers. “I didn't have any extremely rude, obnoxious, drunk people,” Ellen Springwater, the winery's tasting room manager, said with relief at 3:30 p.m., a half-hour before the winery closed for the day. It's too early to say whether the barrel event, which occurs on back-to-back weekends the first part of this month, has shed its rowdy ways. But the early returns Saturday were positive. “We haven't been overwhelmed at all,” said John Balletto, who owns a winery on Occidental Road.
