JS James Suckling: 98 Points
Wonderful blackberry and blackcurrant aromas here with hints of mint and fresh sage. Some cassis. Wrought iron, too. Full-bodied, tight and elegant with lovely tension. Beautiful. Ends fine and focused. Drinkable now, but better after 2022.
WA The Wine Advocate: 97 Points
A blend of 64% Cabernet Sauvignon, 18% Cabernet Franc, 9% Petit Verdot and 9% Merlot, the deep garnet-purple 2017 Proprietary Red soars out of the glass with notions of baked blueberries, plum preserves and blackcurrant cordial, backed up by nuances of chocolate mint, wild sage, violets and pencil shavings, plus an earthy hint of Chinese five spice. The rich, seductive, full-bodied palate is jam-packed with spicy black fruit preserves, framed by wonderfully plush tannins and a lively backbone, finishing long and opulent.
