De Iuliis is located in the Hunter Valley, New South Wales, where cool-climate conditions shape distinctive wines from classic Australian varieties. The winery's Single Vineyard Sémillon demonstrates the region's particular affinity for this white grape, delivering the mineral precision and age-worthiness that define Hunter Valley Sémillon at its best. Alongside this flagship white, De Iuliis produces Shiraz wines—including the Steven Vineyard expression—that reflect the valley's capacity for structured, complex reds. The winery's portfolio has attracted attention from major international critics including Wine Advocate, Wine Spectator, Wine Enthusiast, Decanter, and Falstaff, reflecting the quality of its core range.
