For thousands of years nearly everyone has tried to conquer Sicily, and nearly everyone has left something in their wake. The Phoenicians left vineyards. The Greeks left temples. The Arabs left agriculture.
It's an island that is by technical terms Italian but ask anyone who lives here how they identify this mosaic of cultures and the answer you'll get is that it is distinctly Sicilian — end stop. Likewise, all of these populations have touched viticulture in their own way, resulting in a rich winemaking ethos entirely unique to this ancient island in the Mediterranean.
