The Weather Channel's George Zaidan talks about how Ice Wine is made.

When the thermometer hits seven or eight degrees below zero, the winemaker rushes out to the vineyard, picks the grapes by hand, rushes back to the winery and presses them while they're still frozen. Why do they need to be frozen? Well, the answer lies in my favorite subject, chemistry.

A grape is mostly water, sugar, and flavors... kind of like my stomach on a Friday night, but that's not important. What matters is that water has a dirty little secret. In its liquid form, water is like a public golf course. Anyone is allowed to play. Sugar, salt, acids, bases, what have you. But, when water freezes, it turns into an exclusive country club, thumbing its nose at those other molecules. Only H2O is allowed in.
