Willunga 100 is in McLaren Vale, south of Adelaide.
The grapes for the Willunga wines come from a range of selected vineyards in McLaren Vale and Adelaide Hills, including some over 50 years old.
Wines were made by Steve Pannell and Kate Day up to 2010 and now by Tim James and Kate Day.
They use modern equipment alongside traditional winemaking techniques, including open-top fermenters, to ferment the small parcels of fruit arriving at the winery.
Willunga 100 aims to produce unique and distinctive wines which capture the essence of the region.
