Wine Advocate-Parker :
The 2006 Brut Millésimé spent nine years on the lees and was disgorged in 2017 with ten grams per liter dosage. The wine expresses the sunny vintage, exhibiting generous aromas of mirabelle plum, crisp yellow orchard fruit, confit citrus, toasted nuts and dried white flowers. On the palate, the wine is full-bodied, ample and mouthfilling, with a youthfully boisterous but elegant mousse, a fleshy core of fruit and a rich, expansive finish. This is a gourmand vintage of Heidsieck's vintage Brut, and it will be best enjoyed at table; it will age more on its concentration and extract than its acidity. The blend is a classic 59% Pinot Noir and 41% Chardonnay.
