One of the most informative seminars at the Food & Wine Classic was taught by sommelier (and James Beard Award winner) Belinda Chang. She's made her name as the wine director at The Modern restaurant in New York City. The 2011 Outstanding Wine Service Award winner — whose seminar was titled "Bling vs. Bargain? Guess the Wine Price" — tackled the question of whether price makes a difference when it comes to wine.

Attendees tasted two glasses of sparkling, Chardonnay, and Bordeaux blends, respectively, and were asked to guess which was higher-priced. While we assessed each wine's value, Chang also shared details on what goes into the price of wine. Better understand why a wine costs what it does after the jump.
