Grapes for Diana Madeline are grown to the most fastidious biodynamic farming principles, crucial for optimising quality of fruit and intensity of flavour while infusing the wine with velvety structure and ultra high quality tannins. The vines were originally planted to granitic soils in the central Willyabrup subregionb by Di Cullen in 1971, the meagre yields of two tons per acre sublimate into harvests of the most concentrated fruit. Grapes are picked at baumes ranging from 12Ëš to 13.8Ëš, gently handled and sorted with great care. Varietal components are inoculated to natural yeasts and separately vinified. The finished wine was matured fourteen months in a selection of the highest quality French oak barriques.
