This wine should really be called Volteo Blanco, since it's a Spanish white wine blend. I'm assuming that the three grapes used to make it are in the name because most Europeans think that Americans only buy wine that has the varietals in the name. That most of us have no idea what viura or viogner are probably never occurred to the folks behind Volteo ($10, purchased).
Having said that, it's quite well made and (with its tempranillo cousin) was in consideration for the 2011 $10 Hall of Fame. That it didn't get in speaks more to its newness; this is one of the first vintages, and I'd like to see what happens next before I elevate it to the Hall.
Viura is a traditional Spanish grape used to make just this kind of wine. Look for a crisp, fresh, clean effort with a bit of lemon fruit and Spanish minerality and acid. Don't expect a New World citrusy wine -- the Volteo is much more balanced. Serve this with salads, almost any kind of grilled fish, and even boiled shrimp. And, like the tempranillo, it has the "Smart Label:" A blue frame appears around the label illustration when the wine is at the correct serving temperature. Which actually did work.
