All Cullen Wines are grown on a certified Biodynamic, Carbon Neutral and naturally powered estate. Grapes are harvested by hand on fruit and flower days according to the astrological calendar. The wines have no additions of yeast, acid or malolactic culture, and are in this sense natural wines which express the place and land on which they are grown, the vintage and the people.

Put bluntly, this is perhaps the finest young Australian Cabernet I can recall seeing. It is simply brilliant... There is immaculate balance and amazing intensity and yet the wine dances with freshness and energy. The image that keeps appearing here is Muhammad Ali at his peak, dancing with grace. The more time in the glass or in an open bottle you can give it, the more rewards will come. Surely one of the greatest Cabernets made in this country, perhaps Vanya’s best ever, and it confirms that 2023 in Margaret River, a region of seemingly endless fine vintages – is truly special. Why not 100? I do feel it deserves it, but I simply do not trust Vanya not to come up with something even better next vintage. Rating: 99 Points; Ken Gargett

The 2023 Diana Madeline is an exciting wine. The 2023 season was mild, dry and quite spectacular. There was some rain at the very end of the red harvest, and this was a very site-specific thing, not widespread over the region. Aromatically, the wine is intensely perfumed: graphite and pressed lavender, wet rose petals, raspberry pip, licorice, concrete and summer rain. This gives everything that I could hope for in an early-release Cabernet: dark fruit and exotic spice, mineral detail and more. The chalky and fine tannins shape the palate and spool out long over the finish. Is this the finest and best Diana Madeline made to date? Perhaps! What a wine. Highly recommended. It's the perfect example of great Australian Cabernet: power without weight. Look no further. 13.7% alcohol, sealed under screw cap.

This Diana Madeline delights as soon as it's poured. A deep, dark purple-red and so vibrant. Ah the aromas next – all cedar wood, oak spices and warm earth with fresh mulberries and blackberry essence. It has concentrated, fabulous fruit on the fuller-bodied palate yet there’s a fineness, too, with supple tannins enmeshed in lively acidity. It’s a gorgeous drink. Too young now as it’s still showing off its youthful exuberance. Give this a few more years in the cellar to build more complexity and detail; it's guaranteed to age beautifully for another two or so decades.

Very deep, saturated, inky purple colour. Superb aromas of cedar, sandalwood, blackberry and mulberry, all this translating well to the palate which is very intense, bright, very firm and boldly youthful. A very young wine of enormous potential. I'd cellar it at least four years before broaching it.
