For me I do two ratings of a btl. The current and the potential. When i say a wine is 100 pts it is strictly based on me drinking it at that point. it depends on evolution of btl. I should add the 61 margaux was drunk 10 yrs ago and the 66 fonseca 2 years ago.
When drunk at that time they were perfect. Ive had some of the wines on your list napa
Ill use the 2002 Shafer. A very very lovely wine but it still has too much tannins at this stage last year for me to consider it perfect but i could certainly see it getting there. I would probably still give it a 100 pts for potential but its not there yet. My worry is that it might turn out like the 2002 maya dalle valle which got strangely flabby 3 years ago
