Fruit is sourced from some of the oldest vineyards in the McLaren Vale to utalise the range of "terriors" that are located through out the region. Sandy soils provide lifted aromatics, and darker soils including 'Terra Rosa' types contribute to rich, bold tannins.

All the vineyards are managed to produce the highest quality possible with only the best parcels selected for Willunga 100. McLaren Vale has a warm Mediterranean climate with a strong influence from the gulf of St Vincent - giving cool maritime evenings perfect for ripening grapes.
