Yes i also remember the first australian wine to sell over $20 was either the 1983 vintage of Penfolds grange or the grange that was released in 1983. How times and marketing have changed.

So imagen what that Henschke Hill of Grace Methuselah 1991 bottle will be worth in another 10 to 20 years time.

It would be a great investment for the private superfund if you could hide it somewhere and not be tempted to drink it.

Also the bigger the bottle the slower it matures so it would in theory still be drinking well till at least 2040 if cellared correctly.
