1997

Turning to vinegar as WW says would be the result if left too long. Turning Leaf should probably be consumed within a year of purchase (once the vintage is released to stores).
If you want to add red burgundies to your collection, 1999 was a good year and some of the 99's are still available (2000 is starting to appear also). Good village wines such as Gevrey-Chambertin or Chambolle-
Musigny might be found for under $30. Premier crus wines such as Morey-St.-Denis
Millandes or Volnay 1er Cru might be available for $30-50 a bottle. Many of the 99's are enjoyable now but could age for another decade and perhaps develop more complexity as they mature.
