How do you become a great sommelier? Study helps, but as these five young sommeliers demonstrate, that's only the beginning. It takes a person who can banter with customers as easily as he can rattle off Burgundy's Grand Cru vineyards; who can manipulate numbers as easily as he can bottles that need to fit into cramped spaces; who's strong enough in body and soul to haul 50 cases an afternoon down to a cellar and still be smiling at 11 p.m. And he's got to be as approachable as he is smart. We asked hundreds of leading sommeliers in America to pick the most promising new talent in the business today. In the pages that follow, Tara Q. Thomas profiles the five finalists, our Best New Sommeliers of 2005.
