Our Wines, Our Terroir
The Côte des Blancs is the heartland of Chardonnay — and Le Mesnil-sur-Oger is its capital.
The Land
The Côte des Blancs
Stretching south from Épernay, the Côte des Blancs is a narrow escarpment of east-facing chalk slopes that catches the morning sun and drains quickly — creating ideal conditions for the Chardonnay grape.
At its southern tip sits Le Mesnil-sur-Oger — a village of barely 1,000 inhabitants that produces some of the most celebrated Chardonnay in the world. Delamotte has called this village home since 1760.
The chalk bedrock here is a unique geological formation — Belemnite chalk from the Cretaceous era — that gives the wines their characteristic mineral tension, salinity, and exceptional capacity to age.

GEOLOGY
THE CHALK BELOW
The Belemnite chalk beneath the Côte des Blancs is 70 million years old. It acts as a vast reservoir — absorbing winter rain and slowly releasing it through the growing season, keeping the vines under controlled hydric stress.
This geological gift is the source of the mineral character — the chalkiness, the saline finish, the electric freshness — that makes Delamotte Blanc de Blancs impossible to replicate anywhere else.
