Halliday Wine Companion - 97 Points

Diana Madeline. The name evokes a lot of emotions, for what the woman stood for then and what the wine stands for now. The 2021 vintage equals 50 years of cabernet sauvignon plantings at Cullen. When released in early 2023, it was on what would have been her 100th birthday. It’s a wine that can come from nowhere else, so strong is its sense of place. Expect to swoon over aromas of roses, violets and mulberries doused in baking spices, a ferruginous quality as much as detailed if persuasive tannins. It’s complex, complete and structured. Gosh, what a wine. What a woman. The perfect combination. Jane Faulkner

Tasting Notes

• Aroma: Cassis, violet, and blackberry interwoven with cedar, graphite, and fine spice.

• Palate: Intense yet graceful with layers of dark berry fruit, cocoa, and savoury herbs framed by fine-grained tannins and precise acidity.

• Finish: Long, elegant, and mineral, lingering with notes of blackcurrant, bay leaf, and forest floor.

Food Pairing / Serving Suggestions

An exceptional match for roast lamb, venison, or beef fillet. Also superb with truffled dishes or hard cheeses like aged Comté or cheddar. Decant before serving to allow the full aromatic spectrum to unfold.
