50 to 79 is just passable to fine. A wine that is not faulty.
80 to 84 is good. An every day drinking type of wine.
85 to 89 is very good. A wine that is something better than every day drinking.
90 to 94 is extremely good. A wine that has something quite special about it.
95 and above is outstanding. An amazing wine to treasure.
The commentary is more important than the score.
