The historical site at Caversham in Swan Valley, was acquired by the Erceg family from the Roe family, who had owned the land since settlement in the 1840s. Originally granted to the Swan River Colonies First Surveyor General, John Septimus Roe, it was always the intention of the new proprietors to preserve the cultural and historical heritage of the property, as well as to realize the full potential of Swan Valley as a world class winegrowing region.
Mandoon's focus is on producing a boutique range of premium wines from an inventory of closely husbanded, low yielding single vineyard sites in the Swan Valley and other prominent Western Australian regions, by employing traditional practices that articulate fully, the varietal expression of a great viticultural region.
