The heir to the d'Arenberg wine dynasty is one of the most colourful characters in the Australian wine industry - but he has excelled himself with the new "cube" he is building in McLaren Vale, South Australia.
The high-tech new cellar door will open next year but Osborn has alread inveiled key details.
The five-storey $14 million glass-encased steel and concrete structure inspired by Rubik’s Cube is the realisation of a 13-year dream.
Osborn, 54, is the chief winemaker and futurist for the company his great grandfather Joseph Osborn founded 104 years ago but is equally well known for his love of art and his eclectic and eccentric collection of shirts.
His audacious Cube – an architectural puzzle four modules wide, four high and four deep – is already soaring above the surrounding vineyards in the heart of McLaren Vale, a 40km drive south of Adelaide.
Due to officially open in May 2017, the Cube promises to offer an assault on the senses of anyone who ventures inside.
It will be filled with art installations, a “wine fog room”, flagons connected to bicycle horns to ‘beep’ the smell, wine tasting rooms, a restaurant, and a top balcony made of two-tonne glass panels.
