Of the 17 wines in the ‘Exceptional’ category of Langon’s Classification of Australian Wines only four are cabernets. Cullen Wines’ Diana Madeline Cabernet Merlot shares the stage with another Margaret River icon, the Moss Wood Cabernet Sauvignon. Indeed, both wines reflect their respective winemakers’ uncompromising approach to quality and obsessive attention to detail. No wonder these superior talents have lifted their wines to world-class status in a remarkably short period of time!

The results of this conversion (the vineyard was certified biodynamic in 2003 and the winery in 2008) is clearly demonstrated in the fresh, elegant style of the Diana Madeline. As a result of the use of biodynamic viticulture, Cullen has seen a marked improvement in the structure and oxygenation of the soil, which in turn has enhanced the tannin ripening of the fruit. Consequently, the grapes can be harvested earlier at lower sugar levels and higher acidity.

Indeed, Lisa Perrotti-Brown of the Wine Advocate cites the 2008 Diana Madeline as “another example of Cullen’s emerging ability to achieve physiological ripeness at lower alcohols … Read the rest
