Civilization was built on the discovery that sparks fly when two hard surfaces such as flint and steel are struck against one another. Our wine, drawn from top Napa Valley vineyards, exemplifies the crisp elegant flint and steel characteristics coveted in sauvignon blanc. Chill until you see the orange spark, then enjoy! - Derek Benham, Proprietor. FlintandSteelWines.com. Alc. 13.8% by vol. Cellared & bottled by Flint & Steel Wines, Graton, Sonoma County, CA.
