If you're looking for a light, slightly fizzy, and fun white wine, look for the Broadbent Vinho Verde. This Portuguese white wine is lower in alcohol than typical white wines, and is bottled with a little added carbon dioxide to give that characteristic spritz. The name Vinho Verde literally means "green wine," but fear not: this wine is white in color. The name refers to the youthfulness of the wine; you want to make sure to drink the freshest, most recent vintage. (Often you have to look at the back label to find this information.) Enjoy this wine with light seafood dishes, especially ceviche.
Other producers make fine versions of this style of wine as well. Please note that Vinho Verde is a region that produces more than just the light, spritzy white wine I have described. I contacted the Viticultural Comission of the Vinho Verde Region and received clarification from Marketing Director Carla Cunha, who stated: "In fact the Vinho Verde Region produces several styles of wine: single varietal or blended, dry or semi-dry, with or without gas, more floral or fruity, sparkling or brandy, white, rosé or red. You will find some white wines with a spritz and others without it but they all share the some freshness and lightness naturally produced in this region."
