Notably ...
Ditto for the 1999.The Sandeman web site wrote: "Sandeman Porto Vau Vintage 2003 is a Vintage Porto of exceptional quality and modern style that may be enjoyed while still young or after ageing...".
For some reason there's nothing on the 2011 Vau, but my understanding is that it has the same aim.
I've done quite a bit of searching, but have, as yet, been unable to find out exactly what they do differently, or what is different, such that these wines "... may be enjoyed while still young".
I'm betting someone here (quite possibly everyone here) will be able to enlighten me, for which I thank them in advance.
