Making wine on Europe's largest active volcano doesn't come easy. Frequent changes in topography, elevation, and weather influence each vintage and every winemaker has an interpretation of the evolving volcanic landscape.

Today, the UNESCO Heritage Site is a destination for the world. American wine expert Benjamin Spencer goes beyond the vines to explore the history and rebirth of the region that has everyone talking about Sicily.
