2020 Cullen Diana Madeline Cabernet, Margaret River

A perfumed bouquet, the purity of the fruit in a cassis/redcurrant/blueberry spectrum. The small berries of a quasi-drought summer might have imposed awkward tannins, but the medium-bodied palate is so perfectly balanced it has a drinking span of 30 years and counting.

98 points Halliday's Top 100 Nov 2022

Has the usual estate blend of cabernet sauvignon, merlot, cabernet franc and malbec (92/4/3/1%), the grapes hand picked on fruit days between early February and early March, the components matured in French oak (50% new) for 13 months. The perfumed bouquet has already soaked up the new oak, the purity of the fruit in a cassis-redcurrant-blueberry spectrum. The small berries of a quasi-drought summer might have imposed awkward tannins, but the medium-bodied palate is so perfectly balanced it has a drinking span of 30 years and counting.

Dark, deep and a really youthful purple colour in the glass. Lifted and complex aromas of cedar, graphite, blackberry, brambles, violets and a briary underbrush edge. Full, rich, layered and complex, lashings of mulberry and blackcurranty fruit, firm, granular, textured tannins and lively acidity. Just beginning its journey and what a journey it shall be.
