Italy 11 products.

With more than 350 authorised indigenous varieties and an uninterrupted viticultural presence since Magna Graecia, Italy is the world's largest wine producer by volume in most years. The twenty administrative regions host twenty-four DOCGs and more than three hundred DOCs, alongside a growing number of IGTs that since the nineteen-eighties have provided the framework for significant stylistic innovation.

The classification system combines geographical denomination with variety and production style. The DOCG is the legal apex, although it does not in itself guarantee higher quality than a DOC or an IGT — wines such as Sassicaia or Ornellaia appeared for decades as Vino da Tavola. The major reference regions are Piemonte (Nebbiolo, Barbera, Dolcetto), Toscana (Sangiovese) and the Veneto (Corvina, Garganega, Glera), although international interest has extended to Sicily, Sardinia and Campania over the past two decades.
