Family run Champagne house with Grand Cru Chardonnay, Coteaux Sézannais Pinot Noir, and a Special Club bottling.
The producer
Champagne Pertois-Moriset was founded in 1951 when Yves Pertois and Janine Moriset married and created an estate in Mesnil-sur-Oger. Their granddaughter Cécile Bauchet now manages the family run, independent house with her husband Vincent. The vineyard covers 20.70 hectares across the Côte des Blancs and Coteaux Sézannais. Chardonnay is planted as 100% Grand Cru in the former, while the latter holds Pinot Noir and Chardonnay. A 2009 pressing center uses stainless steel membrane presses, and the cellar often blocks malolactic fermentation.

The story
A Marriage Became A House
In 1951, Yves Pertois and Janine Moriset married and decided to create their own estate in Mesnil-sur-Oger. The marriage united two historic Côte des Blancs winemaking families, bringing their family names into one Champagne house. Both surnames remain in the name Pertois-Moriset. Their granddaughter Cécile Bauchet currently manages the estate with her husband Vincent. The vineyard spans the Côte des Blancs and Coteaux Sézannais, with Grand Cru Chardonnay in the first area and Pinot Noir and Chardonnay in the second.

The Producer
When Yves Pertois and Janine Moriset married in 1951, they decided to create their own estate in Mesnil-sur-Oger. Their granddaughter Cécile Bauchet now manages the family run, independent house with her husband Vincent.
In the vineyards, Pertois-Moriset uses sexual confusion across all plots, a pest management method that disrupts mating cycles and reduces the need for chemical intervention. The estate also deployed the region's first 100% electric tractor for mechanical vineyard work. In the cellar, a pressing center installed in 2009 uses two stainless steel membrane presses.
Place
Chardonnay is the sole grape in the Côte des Blancs holdings, where 13.4 hectares are planted as 100% Grand Cru Chardonnay. Grand Cru is a Champagne vineyard classification, so the term describes the status of the source rather than a grape variety.
The Coteaux Sézannais area covers 7.3 hectares, planted with 60% Pinot Noir and 40% Chardonnay. Pinot Noir introduces a red grape to the vineyard composition, while Chardonnay is present in both terroirs. Mesnil-sur-Oger remains the home village of the house created by Yves Pertois and Janine Moriset.
Wines
The range draws on Chardonnay from the Côte des Blancs and on Pinot Noir and Chardonnay from the Coteaux Sézannais. It includes a Special Club bottling, a designation available to members of the Club des Trésors de Champagne.
Champagne gains its mousse through a second fermentation in bottle. Lees contact can add roundness and texture, while Pertois-Moriset often blocks malolactic fermentation, leaving more malic acidity in the wine and allowing extended bottle ageing.
Final Word
Pertois-Moriset rejoined the Club des Trésors de Champagne in 2015 and is one of only 28 grower producers authorized to make a Special Club bottling.
