Vintage Charts should be used for a generalized guide in lieu of specific knowledge about a bottle or producer.  The better wines from a vintage will generally have longer lives and cellar better.  The ratings are as follows:

RATING:

95-100 Spectacular.  Most producers made very good wines at all levels
90-94   Excellent.  The best wines should be great.  Consistency throughout the vintage.
85-89  Very Good.  The best producers made top wines.  Inconsistent thru the lower levels.
80-86  Good.  Many producers made good wines with some inconsistency at the bottom.
75-79  Middling.  Choose your producers carefully. Only the best may have made a top wine. 
70-74  Below Average.  Tough vintage to make good wines.
Under 70  A Poor vintage.  Spend your money very carefully.
