The historic Turkey Flat property, located within Section One of the Hundred of Moorooroo, is planted to rich, alluvial soils, adjacent to Bethany Creek at Tanunda. The site was sold to Gottlieb Ernst Schulz in 1865, a successful butcher who established a thriving retail business among the vines. Butchering developed into dairying, but the vineyards were always kept, until Peter and Christie Schulz made the transition from fruit growing to winemaking. The distinctive script on the Ancestor label is drafted from the 1888 Schulz family butchers ledger, discovered while restoring the Turkey Flat property in 1992.
