About this WINE
Winemaker and environmentalist Vanya Cullen, a strong believer in biodynamic viticulture, has harnessed the rhythms of the cosmos, Earth’s energy and vitality to ‘achieve greater individuality of site through working with nature rather than against it’. In 1966 her parents Dr Kevin and Diana Cullen planted a trial one-acre (0.4-hectare) vineyard on their sheep and cattle property at Wilyabrup in the Margaret River.
A new vineyard was planted in 1971 with further plantings in 1976 and 1988. The low-cropping, 28-hectare, dry-grown estate is a riot of colour and biodiversity. Vanya Cullen is convinced that biodynamic principles have shaped the quality, character and consistency of the fruit. Her devotion to ‘quality, integrity and sustainability’ in vineyards and winery have resulted in something extraordinary and special. The Diana Madeline Cabernet Merlot is all about vineyard character, finesse, flavour and longevity.
The hand-harvested grapes are picked when the fruit has achieved optimum tannin ripeness, flavour development and acid balance, usually when the moon is running high. The introduction of sorting tables and minimal handling has further improved quality. Between 10 and 50% of the wine is partially barrel fermented; the rest is given extended maceration before further maturation in 30% new, tightly-grained French oak
Located on the most south-westerly point of Australia, three hours’ drive south of Perth, the Margaret River region sprang to life during the 1960s and 1970s as a result of Professor Harold Olmo’s and Dr John Gladstone’s research into the region’s viticultural potential. Consequently Vasse Felix was planted in 1967, Moss Wood in 1970 and Cullen in 1971. Since then the plantings have grown exponentially, while the number of wineries has increased six-fold. This explosion of wineries has perhaps been to the detriment of the wine quality.
Bounded to the west by the Indian Ocean and the 90km Cape Naturaliste to Cape Leeuwin promontory, the region enjoys a benign if damp maritime climate in which the vines rarely shut down, causing disrupted flowering (exacerbated by strong, westerly sea winds). Over the growing season it’s 16 percent hotter than in Coonawarra and 7% than the Médoc.
The Cape ridge is made up of lateritic clay topsoils over weathered granite and gneiss, giving fruit with a relatively high pH. Cabernet Sauvignon is the most fancied variety,producing a lush, early drinking style, followed by Shiraz, Chardonnay and Sémillon.
The main grape for Sauternes and particularly successfully grown in Australia's Hunter Valley. Hunter Valley Sémillon is one of Australia’s iconic and unique wines, totally unlike any wine produced elsewhere in the world from the same grape variety.
In youth the wines are quite citrusy and fresh, but are generally perceived to gain hugely in complexity as they age and are deemed to be best drunk when at least 5 years old, frequently lasting for 10 or more years. Unusually for Australia, the alcohol levels rarely exceed 11.5%.
In Bordeaux it is the most widely planted white grape and is blended with Sauvignon Blanc to produce the great long-lived dry whites of Graves as well as the great sweet wines of Sauternes. It is high in alcohol and extract and relatively low in aroma and acidity. Its thin skin makes it very susceptible to botrytis which is prerequisite for the making of Sauternes. It responds well to oak ageing and, while having a lightly lemony aroma when young develops lanolin flavours which some describe as "waxy", as well as a rich, creamy, intense, texture and a deep golden colour.
