Actually, that's not true. The common misconception is that the older the wine, the better, and the more people will pay for it. True, there are vintage wines that have a hefty price tag, but some ''old'' wines are just that; OLD. Your whites, ie. chardonnay's, tend to 'turn', or go bad, after a small number of years (3-6). Then you're stuck with a bottle of vinegar.
Also, even, for example, a vintage red, such as a Cabernet Sauvignon, can go bad prematurely if the cork is bad, or the bottle is not stored correctly.
So, in other words, if someone's holding on to an old bottle of wine because they're gonna cash in when it's 20 years old...most likely you can use it to cook with tonight. Bon Apetit.
