No lineup of autochthonous varieties has seen such international success as those from Sicily. Cultivated in a variety of soil types and microclimates, these indigenous grapes are the backbone to some of the wine world's most versatile, food-friendly, and easy-drinking wines, and though other viticultural zones are also home to a plethora of native grapes, few regions – if any – have seen the market domination that Sicily has. Nine industry professionals have some hunches as to why.

Numerous professionals agree that the wanderlust aspect of Sicily has played a large role in consumer attraction towards its indigenous wines. Charlotte Berdensey, ex-beverage director at Momofuku and currently of Skurnik Wine and Spirits, notes that Italy as a whole has a strong intrinsic lure in terms of history, food, travel, and wine.
