Which wine (NOT a specific vintage) would you like to drink sometime?
Producer and maybe special cuvee, cru or vineyard … but not a special (great) vintage - so 1945 Mouton does not qualify.
My choice: Henri Jayer Vosne Romanee Cros Parantoux
I had Cros Parantoux by Meo-Camuzet and Emmanuel Rouget before, but not by HJ.
Kebir-Impérial from Frédric Lung.
Flawed question. There’s no good wines only good bottles from good vintages. 84 Jayer Cros - yummm. 
Ok, flawed question, so forget it …
(self-evidently everybody prefers a sound bottle from a good vintage)
Sparkling Chambertin or Clos Vougeot, which used to exist.
I’ve actually seen a photo from a CV-sparkling bottle but of course never tasted one …
I’ve had a sparkling red village Gevrey from Bouchard. Nothing to write home about… (or drink 
).
You should read Jacky Rigaud’s Henri Jayer book. Henri rates vintages and you might be surprised by some of his opinions, not always in line with what you think you know. It doesn’t negate the point that vintage matters, of course, only that there’s more to it than popular pronouncements.

Leflaive Montrachet. It’s the only “great” which I’ve never even sipped from any vintage.

A few Aussies, that either through generally low production, or lack of exports, are rarely if ever seen over here e.g. Seppelts Drumborg riesling, Brown Brother Shiraz, Mondeuse, Cabernet Sauvignon (a wine that sounds most unlike their better known varietal range, and one reputed to cellar well) and Wendouree (I’m not entirely sure I’d like them, but have always wanted to find out, with the Shiraz Mataro/Mourvedre appealing most).
Edit: One more, and this arguably more of an icon wine. Seppelts(field) Para port. There’s something very special to my mind, that a producer might make a barrel of wine, and then set it aside intentionally for 100 years, before releasing it when all involved in it’s production are long dead.
That would be on my list as well along with D’Auvenay Chevy. Both very hard to find in any circle.

The Henri Jayer I had was a 1986 Vosne-R Village - a vintage I usually avoid because I find most wines overal acidic and lacking fruit - but this Jayer was simply stunning (so far about mean vintages!)
I had Leflaive Montrachet once, the 1996 vintage, and it was quite disapointing 
- it was totally closed (in about 2009/10), there was the feel of power, but not much else, neither in the nose nor at the palate - the two other wines besides it completely stole the show (M. Amiot 1999, Laguiche 2000). No idea how it would perform today - 
Definitely one to search out - I had about 10 bottles, all outstanding to simply great
Pretty much anything that @Francois_Audouze is opening 
A Fred Arterberry wine from the ‘80s. This option hasn’t yet presented itself for me.
