So you think you know wines? When you get tired of wrapping Christmas presents, take a break and head over to Dr. Vino's year-end quiz of wine esoterica . You can win a case of wine or one of several other cool prizes.

Grand prize: a case of wine! Yes, an excellent mixed case (12 bottles) of wines in the Dr. Vino price range, including wines from Spain, France, Chile, and the US--including reds, white and a great rosé (Las Rocas!). This prize, awarded to one randomly selected participant with a correct quiz, is generously donated by Wine Discount Center, 1826½ N. Elston Avenue, Chicago, IL 60622. Second (and third and fourth prize): Shafer Vineyards has compiled ten years of their witty newsletters in the excellent volume, Line on Wine. And the Essential Wine Guide, a discrete and compact guide of bite-sized but essential notes for wine tasting. Three of these sets are available to randomly selected winners. These prizes are generously donated by Shafer Vineyards and the Essential Wine Tasting Guide respectively. All submissions must be received by January 3, 2005. Winners will be drawn from the best scores at random.

Ready, set, corkscrew, go.
