Heidsieck Cuvee Rare is a blend of 17 crus which were aged for over seven years in the House’s cellars. The blend is 70% Chardonnay and 30% Pinot Noir, both from Montagne de Reims. The appearance is a dazzling, crystal-clear, citrine yellow gold enlivened by a delicate, shimmering effervescence. The fruit emerges as delicate and golden, with muted exotic fruits (mango and kiwi) and notes of hazelnut, almond and fig. Mild spices (white pepper, smoked tea and cocoa) reflect the wine’s depth but are honed, precise, and in harmony. The palate is voluptuous, with meringue-like delicacy, while nuances of mint tea, lime, kumquat, pineapple and candied ginger evoke distant lands.
