In the early 1960's detailed climatic studies of various regions in Southwestern Australia revealed that during the winegrowing season, Margaret River's climate was similar to that of Bordeaux, particularly Pomerol. The conclusion that Margaret River was ideal for viticulture was first tested in Wilyabrup in 1966, when Diana and Kevin Cullen planted a trial acre of vines. The encouraging results led to the couple planting 18 acres of vines on their sheep and cattle farm in 1971.
Cullen Wines while remaining family owned has since evolved making quality wine from biodynamically grown grapes sourced exclusively from The Cullen Estate Vineyard and Mangan Vineyard
In his book 'Wisdom of the West' Bertrand Russell states that "Philosophy is as the Greeks put it a kind of adventure undertaken for its own sake."
The vineyard site at Cullens was carefully chosen for its potential to produce great wine, and in particular red wine.
The philosophy of Cullen Wines is to search for the best quality expression of the vineyard in the wine. The maritime climate, rocky soils, dry farming, and biodynamic practices all help to create individual and diverse winestyles which are unique to Cullen.
