A subsidiary of Accolade Wines, the company operates four of Western Australia's largest vineyards at Moondah Brook (145 hectares), Pemberton (92 hectares), Mount Barker (74 hectares) and Frankland River (89 hectares), and sources fruit from Margaret River, Harvey and the Ferguson Valley. Expansion into the Western Australian South West and the Great Southern wine region led to the establishment of a winery, located at Nannup in the Blackwood Valley. In 2019 Houghton divested itself of its wine producing facilities and vineyards in the Swan Valley.
