Langton's Exceptional Classification. Diana Madeline is one of Australia's great icon wines, crafted from fruit grown to one of Margaret River's earliest sites. The vines, planted in 1971, provide a scant two tons per acre, yielding grapes of amazing concentration. Cullen have returned to the old world practice of basket pressing. To their delight, they have found that this leads to the extraction of only the finest tannins. A stately construct in statuesque Bordeaux styling, deeply coloured, the extraordinary depth of flavour reflects an outstanding quality of fruit.

In accordance with biodynamic principles, all fruit is hand harvested from vines up to forty years of age. A patented Mistral® apparatus removes the leaf material and infertile berries from the vineyard, providing cleaner bunches. A luxurious cepage of Cabernet Sauvignon and Franc, Malbec, Merlot and Petit Verdot, the grapes are carefully sorted before fermentation to indigenous yeasts and malolactic bacteria. No acid or cultured yeasts are added, achieving a wine with a sense of place through a completely natural process. Components are separately vinified before being treated to nineteen months maturation in a selection of new and seasoned French oak barriques.
