What's the Big Deal about High-Altitude Wines?

There's a big deal? You’re kidding me? Take me higher!

There really is. But, much of the noise is spin. Unwittingly perhaps, certain wine regions, countries and even individual winemakers have developed a "mine's higher than yours" attitude when discussing vineyards' height above sea level. Wine publicists and geeks alike are lapping it up. So, it's important to go beyond the hype and find out what real high-altitude wine is.
