Near Perfect bottle of 1978 La Tache from JK cellar was, in a word:  Kaleidoscopic (right out of the cellar).

The 1991 La Tache is a phenom powerhouse — one of the great LTs — but still needs a 1-2-3 hours of air time — in a wide mouth decanter.  Also from the JK cellar.

The 1989 DRC Montrachet:  incredible butter and pain grille with resolved tannins and just enough acid to hold it all together (who knows how much longer?) — elegant and especially voluptuous.  From the JL cellar.
