Jack Mann is the patron saint of West Australian viticulture, the creator of Houghton White Burgundy and architect of the state's greatest editions. Jack's son was also a winemaker, he advised Swan Valley based Sandalford to establish vineyards in the nascent Margaret River region. Arguably Western Australia's finest and most enduring Verdelho, Sandalford is crafted from fruit grown primarily to these forty year old, dry grown Wilyabrup vines inspired by Dorham Mann.

Western Australia's first Surveyor General, John Septimus Roe established Sandalford in 1840. The estate formed part of the second land title in all of Western Australia. In 1972 Sandalford developed a major vineyard along Margaret River, now one of the oldest and largest, covering six hundred acres. Verdelho grapes are harvested throughout the cool of night across several different dates. Grapes are immediately crushed, chilled and pressed, only the cleanest free run juices are retained. Following clarification and inoculation to a choice strain of yeast, the wine is treated to a long and slow vinification until dryness, followed by assemblage and stabilization, filtration and early bottling.
