The grapes to produce the “Diana Madeline” Wilyabrup Cullen were hand picked and carefully sorted. Each variety was fermented separately with indigenous yeasts. Fermentation time ranged from 10 – 29 days, before the wine was gently basket-pressed to barrel. It matured for 15 months in French oak, of which 45% was new, in a mixture of biodynamic barriques and puncheons.
Located in Wilyabrup, 20 kilometres north of Margaret River township, the soils at the Cullen vineyard are old granite and gravelly, sandy loam, overlaying lateric subsoils. Planted in 1971, the Cabernet Sauvignon comprises 11.33 hectares, while the Merlot was planted in 1976 and covers 1.76 hectares. The conversion to biodynamic viticulture is believed to have produced better fruit, the character of which is preserved during the winemaking process.
