James Suckling gives the wine an excellent review with a score of 94, noting "Wild berries, blackberries and nuts with wood and herbal undertones on the nose. It’s full-bodied with firm, grainy tannins. Savory and well balanced on the palate with a chewy, flavorful finish" (jamessuckling.com).

Jeff Leve from TheWineCellarInsider.com mentions a family resemblance to the Grand Vin, noting it is "lighter, closer to ready to drink and softer for sure" with a "black raspberry and currant profile, coupled with round tannins, a fruit-filled, supple textured finish and hints of tobacco." He scores it a 91 (TheWineCellarInsider.com).

Lastly, Wine Spectator describes the wine as "Reserved in style, but very sleek, with a hint of iron running just under the cover of dark plum and cassis notes. The finish is tightly-grained and focused, with a flash of charcoal at the very end," giving it a score of 91 (Wine Spectator).
