A sommelier's job includes trying to find the best wines to match with your meal, evaluating how a wine will complement the flavors of each ingredient, the preparation, the sauce... But what about the combos that just don't work?

Which combinations just make them cringe? Check out the slideshow for a few wine-and-food matches that you should definitely avoid.
