De Bortoli is Australia's third-largest family-owned winery, established by Italian immigrants Vittorio and Giuseppina De Bortoli in Bilbul, NSW. Now in its fourth generation of family ownership, the company produces a wide range of wines across multiple regions including the Yarra Valley, Riverina, and Hunter Valley, with notable brands including Noble One, Deen Vat Series, and La Bohème. The company remains fully independent and Australian family-owned, a rarity among major Australian wine producers.
