Well, if you had bought one, there’d be some return on investment:
Interesting that Wine Searcher’s algorithm rates it as “one of the most popular wines from Barossa Valley.” Some new definition of “popular”, surely.
Of course, it’s all an enormous exercise in willy-waving. All of the fluff about flying out the winemaker, tungsten tipped bottle openers and silver tastevins - it’s not a wine designed ever to be drunk. Merely possessing a bottle expresses your power and influence (or something like that ). Actually opening it would destroy its value. Of course, you could argue that doing so would show you’ve got the biggest willy of all.
