Old Mill Estate vineyards are owned and operated by Peter and Vicki Widdop. Previously the vineyard was the home of a mill which produced chaff from lucerne grown on the property. The vines were planted in 1993 after a flood inundated the property. Three varieties are grown: Cabernet Sauvignon, Shiraz and Touriga. The vineyard is located near the shores of Lake Alexandrina by the banks of the Bremer River in the well-known wine producing region of Langhorne Creek, approximately 75 kilometres south-east of Adelaide in South Australia
