(Winemag) - There’s more to this easy-drinking, effervescent Portuguese white wine than meets the eye. Learn about the subregions and grapes of Vinho Verde, and what wines to watch for.

If you make a habit of drinking outdoors in the summer, you’re probably familiar with the white wines of Vinho Verde. These slender bottles generally clock in around $15, and stay in the neighborhood of 10–12% alcohol by volume (abv).

Vinho Verde usually has a bit of spritz. Carbon dioxide (CO2) sometimes occurs naturally, but more often, it’s added during bottling. The style also brings ample acidity, making it one of the more refreshing wine options. While value and refreshment are excellent reasons to drink Vinho Verde, there’s more to this Portuguese region than even the savviest wine lover may know.
