Delinquente operates in the Riverland, South Australia's warm inland region known for fruit-forward wines and experimental viticulture. The winery's portfolio centers on Italian varieties, particularly Vermentino—a white grape prized for its aromatic profile and natural acidity. Weeping Juan Petillant Naturel, a Vermentino made in the pét-nat style, and Screaming Betty Vermentino represent the winery's focus on this varietal. The range extends to Montepulciano, the Tuscan red, as seen in Roko Il Vagabondo. These wines have been assessed by Wine Enthusiast and Decanter. The Riverland's warm days and cool nights create conditions suited to both traditional and unconventional winemaking approaches, a character reflected in Delinquente's selection of Italian grapes and natural winemaking methods.
