You can't buy this, so it's more of a progress report than a review. Possibly it's a taunt even.
I've had this a few times now, I've got a small, and thus inadequate, personal stock and it's been on tasting at the Marius harvest at least once. Unfortunately I never tasted it when it was newly released, and the only reason that is unfortunate is that I cannot compare it to the current excellent 2010 release.
What I can say is that, right now, tonight, I think this may be the most enjoyable wine I have ever had. Many years to go.
That's a personal opinion of course, and I have certainly had wines with more wow factor, but there is something immensely satisfying to me in this one. Complexity, intensity, depth, breadth, length, balance, all of the boxes are not only ticked but the words are also circled and underlined.
I had a bottle of the 2010 recently, because I can't leave it alone - and it's likely still available because I am ahead of the curve, so I feel safe-ish that I can restock. Who knows if the 2010 will end up as good as the 06 at the same age, but I reckon it's an even safer bet than Black Caviar.
