I have some Moss Wood CS 2001 under SC, haven't tried it yet but I am 100 % confident that it is developing gracefully.
Also got a case of 2002 Kay Bros Old Block 6 shiraz under SC and had been told buy Colin Kay (Owner/wine maker) not to touch it until 2025.
So the Block 6 now needs 25 years to be approachable! Wow they used to drink well after 5+ years. Something sounds awry there in relation to the closure
My (limited) experience with aged screwcaps is that they do develop nicely in the bottle. I think the development is a bit slower, but not glacial compared to the same wine under cork. The big difference is that screwcaps are intended to put to the sword the old saying that there are no great old wines, only great old bottles. The screwcap does away with the variability of cork to a very large extent (I've had the rare dodgy screwcap) so that those bottles that begin to be affected by flaws in the cork (apart from TCA) get more and more affected as time goes on. Premature oxidation is probably the biggest example of what I mean.
Of course, you may get a wine that has been made magical over the decades due to the vagaries of the particular properties of the particular piece of tree bark used as a stopper. But few of us can afford to hold out for the diamond to shine through the dross and the semi-precious stones. I would rather drink six outstanding wines out of a six-pack than have one sink-job, two ordinary, two very good and one truly exceptional wine.
As for the prediction re the Block 6, it is hard to understand how Colin Kay would know how slowly his wine will age under screwcap. I accept he is the maker, but unless he has already done the experiment in cellaring wine of that standard for 20 years, it may be nothing more than a bit of hyperbole (I don't know Mr Kay, so this is pure speculation on my part, rather than an accusation).
I've had the Shiraz Mataro and the Cab Malbec from the 2011 Wendourees and these were fabulous drinking wines, to my taste, from the get-go. That, of course, is a function of the grapes and vintage, but clearly there was no retardation by the screwcaps in those cases.
I'm just thinking that there might be a confusion between longevity and pace of development. A wine can develop reasonably under screwcap, but hold its level of maximum pleasure for longer. I expect that the quality of the grapes, the cleanliness of the winemaking, the skill of the bottling and the cellaring conditions will have a much, much greater impact on how even Wendourees develop than the choice of screwcap vs non-faulty cork.
