There is a huge difference between the 95, 96 and 97.
The 95 (and earlier) has loads of American Oak, was a huge wine with an old fashioned feel to it that took years to peak.
The 96 used a French Oak component, the wine has far finer tannins, was ready to drink on release, was technicially perfect and almost elegant by comparison to the 95.
The 97 has a great mouth feel with smooth tannins but the fruit is much bigger and more obvious than the 96 and a bit jammy.
Just a few that comes to mind off the top of my head.
