Decanter (Yohan Castaing) 95 points! "This 2004 constitutes only the fifth edition of this special bottling that has earned an outstanding reputation, coming after 1983, 1985, 1990 and the superlative 1995. The Chardonnay for this blanc de blancs comes from the five famous terroirs of the Côte des Blancs: Avize, Cramant, Oger, Le Mesnil-sur-Oger and Vertus. It has powerful aromatic complexity with minty, floral and mineral elements, while the dense, generous yet silky texture is supported by finely-judged acidity. This is a character-driven Champagne that should pair well with a poultry dish based on a creamy sauce."
Decanter (Christelle Guibert) 96 points! "The 2004 follows the legacy of the remarkable 1995. Grapes from four grands crus (Avize, Cramant, Oger, Mesnil-sur-Oger) and the premier cru Vertus. Purity, richness and tension too, with brioche and leesy characters and a hint of lemon. Dense and textured, yet elegant with a real taste of chalk and a very long finish. Spending 11 years on lees, it was disgorged in November 2016. Drinking well now, but one to leave in the cellar for some time."
Decanter (Michael Edwards) 97 points! "It says much that Charles Heidsieck went for the 2004, not the richer 2002, as the long-awaited successor to the epic 1995 Millenaires - the '04 has an admirable beauty and finesse in the classic mould that fits the style of this wine so well. It's an intriguing blend of great Chardonnays from Oger, Mesnil, Avize and Cramant, but also from Vertus, a premier cru punching above its weight. Vanilla and butter flatter this wine famously, but there's no oak. It has controlled richness, with precision and purity ruling over the green and tropical fruits. A magnificent champagne with impressively elegant acidity, a triumph now and for years to come. Disgorged in 2016."
