The Rileys carefully tend the vineyard themselves, applying a minimal amount of water at critical times to produce grapes with superb characteristics for wine production. Each year parcels of grapes are selected for processing in the winery. The production is under guidance by winemaker, Jo Irvine, (Barossa Winemaker of the Year, 2009) to ensure that Rileys of Eden Valley wines are of the highest quality.
The 12ha vineyard is planted on typical Eden Valley soils ranging from deep sands to sandy loams over sandy clays. Originally the vineyard was to be a part time venture but the success of the vineyard soon grew. In 1998 , Terry retired from his position of Professor of Mechanical Engineering at the University of South Australia to concentrate full time on the vineyard and later the winemaking activities.
