I find the '06 very under developed at this stage. Almost flabby with fruit and no crispness at all. I think the '02 has started now to come into its own and I like it better than the '04 right now. The '06 is going to be a keeper I think because with that much fruit intensity it will likely not diminish for a very long time.
Both of them are too young, I had the 97 at home the other day, and that could still do with some years in the cellar. I don't plan to open my '02s any time soon.
The difference between drinking in the air and on the ground is quite staggering.
