d'Arenberg is McLaren Vale's most colorful winery, a fourth-generation family estate famed for eccentric wine names like The Dead Arm Shiraz and The Laughing Magpie — and for the d'Arenberg Cube, chief winemaker Chester Osborn's five-story Rubik's-cube-inspired tasting monument. Behind the theatrics lie serious old-vine Shiraz and Grenache from some of Australia's oldest plantings.
