Champagnes
Mercier Blanc de Noir is described as the house's iconic champagne. It contains only Pinot Noir (80%) and Pinot Menunier (20%), hence the name.
Mercier Brut contains 20% Chardonnay and a relatively high proportion of Pinot Meunier, which prevents the champagne from aging optimally. This champagne is sold young and should be consumed quickly.
Mercier Brut Millésimé contains 50% Chardonnay, primarily from the Montagne de Reims. The grapes used are from a single vintage.
Mercier Brut Rosé, a rosé champagne, is made of 60% Pinot Noir and 40% Pinot Meunier.
Mercier Cuvée Boulle d'Or is the prestige cuvée. Formerly sold under the name Réserve de l'Émpereur, this champagne, which is only produced in small quantities, contains 60% Chardonnay. The bottle bears no vintage.
Pinot Meunier produces a lively, fresh, and floral champagne. The vine is winter-hardy, and the grape ripens early in the autumn, increasing the chances of a good harvest in the northern Champagne region. The fact that the wine from this grape doesn't age as well isn't a problem for a house like Mercier; they prefer an accessible, fresh, and affordable champagne.[2]
