Hi, I just wanted to share my experience with this wine. It's expensive stuff which I felt lucky to get for $185 a bottle. I recently decanted one (my first of two bottles) for about an hour and a half and would say that it may be the best red I have ever tasted.
I've had the good fortune of trying some very high end wines (62 la tache, 55 grange, 53 vega sicilia) as well as many 82 bordeaux and a smattering of other decent burgundies, and while I didn't have any immediate comparison with the Gaja, I really think it would compete with or surpass any of those. Of course it is very expensive but I have to say, if you're going to blow some cash on a big bottle, try the 97 Sperss if you can find it. It's too easy to spend big $$$ just to end up disappointed so I wanted to pass this on.
