Cullen are driven by a passion for purity of fruit and perfect balance in the finished wine. Grapes are picked by hand off vines grown to a strict environmentally friendly philosophy. All wines produced at Cullen are certified as biodynamic, carbon neutral and naturally powered. Cullen vary the ratio of Sauvignon Blanc to Semillon with each vintage according to how the varietals perform. Grapes are individually sorted and fermented to indigenous yeasts, with no acid additions and limited fining, permitting the expression of terroir to have a stronger voice in the glass.

A pure, single vineyard wine. Fruit is picked over three weeks at optimal baumes to ensure that the wine would possess a desired combination of richness and fresh. The complexity of this famous style is also attributable to the marked differences between the characteristics of Sauvignon Blanc produced by seven unique blocks which reflect subtle differences in soil structure and composition. A component is barrel fermented in new French oak before being treated to several months maturation. As with all Cullen wines, the fruit is completely dry farmed, hand picked and sorted before vinification to natural yeasts without the requirement of any acid adjustment.
