Lucky you to get such a pristine bottle. I had an utterly dead '88 version of this over lunch early December 2007:
1988 Nuits St Georges “Les Lavieres” by Leroy > - From Bernie. Murky with worrisome pungent sherry wrapping its decayed Burgundy bouquet. A quick sip revealed a souring finish. Clearly over oxidized, but we decided to keep it decanted and on the table, hoping against hope, just in case.
I kept coming back to it every so often, but it never revived itself. Too bad.
Luckily, a '88 Meo Camuzet Clos de Vougeot, '96 Comte Armand Pommard Clos des Epeneaux and '89 Ostertag Gewurztraminer SGN saved that lunch.
