Don't the wine experts say that no bottle is worth more than $25? The rest is all marketing.
I heard something quite similar - beyond 25$ there's no further increasy in quality, you only pay for special or rare flavour (and big names, off course). Sometimes I think that is also true for most gear beyond a certain price limit...
There's something to be said about some of the high end Bordeaux first growths, or the finest of the Spanish Ribera del Dueros or Priorats, or the best of the Aussie stuff like Penfold's Grange, or the rare(r) California wines in good vintages.
They are all probably worth more than $25 (in that you simply cannot find an analog in a cheaper variant - not consistently, anyway).
That said, most probably aren't worth what they fetch now at wine auctions and en primeur sales. I would argue that a handful of wines might be worth $100/bottle, but it's unlikely to be "worth" $1,000 (or more).
Age helps with the big names, and that's something you pay for if you don't buy en primeur - "ex Chateau" vintage releases will be marked up because you're compensating them for the fact that they had to store it properly for years. Same goes for buying older vintages from respectable wine shops that have proper cellaring facilities.
There's a lot more to it than just marketing.
And, it's worth noting too, that the boxed wines of today are way better than the boxed wines of the past (although there's still plonk!"
Tetra-Pak type wine packaging is starting to catch on too!
Like with all luxury goods that gain value with age/rarity, production cost isn't a factor. I don't think that Neumann put 12.000$ worth of work/value into a single vintage U47
Yes, and it's marketing, too. All those pics of Frank Sinatra and The Beatles singing into them make a difference. There's no objective reason to think the U47 is the greatest mic ever made, or was even worth preserving after production ceased - only the subjective opinion that people like it. If it has been less popular among a certain group of very well funded recording artists, another mic would have held the same stature. It happened to be present during a growing and formative era, so it had a chance.
