Cuvée 4.5

buy online

RSRV Cuvée 4.5 is a unique blend of five of Maison Mumm’s Grand Cru terroirs. Pinot Noir – from Verzenay, Aÿ and Bouzy – confers power and structure, as well as fresh, generous aromas. Chardonnay – from Cramant and Avize – lends elegance and liveliness, as well as tangy citrus notes.

The grapes are pressed and vinified separately before being blended with reserve wines. For the finishing touch, the dosage liqueur – a light dosage of 6 grams per liter – is sourced from these same Grand Cru terroirs.

Produced in limited quantities, this champagne ages for a minimum of four years in the cellars before it is ready to be enjoyed.

The specific shape of the bottle, with its slender neck, enhances the evolution and conservation of the wine.
